RESPIRATORY MUSCLE contraction during INHALATION. The work is accomplished in three phases: LUNG COMPLIANCE work, that required to expand the LUNGS against its elastic forces; tissue resistance work, that required to overcome the viscosity of the lung and chest wall structures; and AIRWAY RESISTANCE work, that required to overcome airway resistance during the movement of air into the lungs. Work of breathing does not refer to expiration, which is entirely a passive process caused by elastic recoil of the lung and chest cage. (Guyton, Textbook of Medical Physiology, 8th ed, p406)

Changes in occlusion pressure (P0.1) and breathing pattern during pressure support ventilation. (1/415)

BACKGROUND: The purpose of this study was to investigate changes in breathing pattern, neuromuscular drive (P0.1), and activity of the sternocleidomastoid muscles (SCM) during a gradual reduction in pressure support ventilation (PSV) in patients being weaned off controlled mechanical ventilation. METHODS: Eight non-COPD patients recovering from acute respiratory failure were included in this prospective interventional study. All patients were unable to tolerate discontinuation from mechanical ventilation. Each patient was evaluated during a period of spontaneous breathing and during PSV. Four successive levels of PSV were assessed in the following order: 20 cm H2O (PS20), 15 cm H2O (PS15), 10 cm H2O (PS10), and 5 cm H2O (PS5). RESULTS: When pressure support was reduced from PS20 to PS10 the respiratory rate (f) and the rapid shallow breathing index (f/VT) significantly increased and tidal volume (VT) significantly decreased. These parameters did not vary when pressure support was reduced from PS10 to PS5. Conversely, P0.1 varied negligibly between PS20 and PS15 but increased significantly at low PSV levels. P0.1 values were always greater than 2.9 cm H2O (4.1 (1.1) cm H2O) when SCM activity was present. When contraction of the SCM muscles reappeared the P0.1 was the only parameter that changed significantly. CONCLUSIONS: In postoperative septic patients the value of P0.1 seems to be more useful than breathing pattern parameters for setting the optimal level of pressure assistance during PSV.  (+info)

Clinical evaluation of a computer-controlled pressure support mode. (2/415)

We have designed a computerized system providing closed-loop control of the level of pressure support ventilation (PSV). The system sets itself at the lowest level of PSV that maintains respiratory rate (RR), tidal volume (VT), and end-tidal CO(2) pressure (PET(CO(2))) within predetermined ranges defining acceptable ventilation (i.e., 12 < RR < 28 cycles/min, VT > 300 ml [> 250 if weight < 55 kg], and PET(CO(2)) < 55 mm Hg [< 65 mm Hg if chronic CO(2) retention]). Ten patients received computer-controlled (automatic) PSV and physician-controlled (standard) PSV, in random order, during 24 h for each mode. An estimation of occlusion pressure (P(0.1)) was recorded continuously. The average time spent with acceptable ventilation as previously defined was 66 +/- 24% of the total ventilation time with standard PSV versus 93 +/- 8% with automatic PSV (p < 0.05), whereas the level of PSV was similar during the two periods (17 +/- 4 cm H(2)O versus 19 +/- 6 cm H(2)O). The time spent with an estimated P(0.1) above 4 cm H(2)O was 34 +/- 35% of the standard PSV time versus only 11 +/- 17% of the automatic PSV time (p < 0.01). Automatic PSV increased the time spent within desired ventilation parameter ranges and apparently reduced periods of excessive workload.  (+info)

A single-center 8-year experience with percutaneous dilational tracheostomy. (3/415)

OBJECTIVE: To determine surgical, postoperative, and postdischarge complications associated with percutaneous dilational tracheostomy (PDT) in an 8-year experience at the University of Kentucky. SUMMARY BACKGROUND DATA: There are known risks associated with the transport of critically ill patients to the operating room for elective tracheostomy, and less-than-optimal conditions may interfere with open bedside tracheostomy. PDT has been introduced as an alternative to open tracheostomy. Despite information supporting its safety and utility, the technique has been criticized because advocates had not provided sufficient information regarding complications. METHODS: A prospective database was initiated on all patients who underwent PDT between September 1990 and May 1998. The database provided indication, procedure time, duration of intubation before PDT, and intraoperative and postoperative complications. Retrospective review of medical records and phone interviews provided long-term follow-up information. RESULTS: In the 8-year period, 827 PDTs were performed in 824 patients. Two patients were excluded because PDT could not be completed for technical reasons. There were 519 male and 305 female patients. Mean age was 56 years. Prolonged mechanical ventilatory support was the most common indication. Mean procedure time was 15 minutes, and the average duration of intubation before PDT was 10 days. The intraoperative complication rate was 6%, with premature extubation the most common complication. The procedure-related death rate was 0.6%. Postoperative complications were found in 5%, with bleeding the most common. With a mean follow-up of greater than 1 year, the tracheal stenosis rate was 1.6%. CONCLUSIONS: On the basis of this large, single-center study, the authors conclude that when performed by experienced surgeons, PDT is a safe and effective alternative to open surgical tracheostomy for intubated patients who require elective tracheostomy.  (+info)

Predictors of weaning outcome in chronic obstructive pulmonary disease patients. (4/415)

Several threshold values for predicting weaning outcome from mechanical ventilation have been proposed. These values, however, have been obtained in nonhomogeneous patient populations. The aim of the present study was to determine the threshold values in chronic obstructive pulmonary disease (COPD) patients and compare them to those reported for nonhomogeneous patient populations. The initial weaning trial included 81 COPD patients. Fifty-three of them underwent a successful weaning trial, whereas 28 failed it. The latter were enrolled into the present investigation, and were restudied during a subsequent successful trial. The weaning indices used were those reported in the literature. The threshold values obtained were within 10% of those reported for a nonhomogeneous patients population only for tidal volume and effective compliance. The classification error was <20% for maximal inspiratory pressure (MIP), occluded inspiratory pressure swing (deltaPI)/MIP, rapid and shallow breathing (respiratory frequency/tidal volume), and compliance, rate, oxygenation, pressure index (CROP), whereas the area under the receiver operating characteristic curves was >0.9 only for deltaPI/MIP and CROP. In conclusion, the threshold values obtained in chronic obstructive pulmonary disease patients who failed the first weaning attempt differed from those previously reported. Although a gold standard weaning index is not available for chronic obstructive pulmonary disease patients, the occluded inspiratory pressure swing/ maximal inspiratory pressure and compliance, rate, oxygenation, pressure index may be candidates for such a role.  (+info)

Comparison of the pressure time product during synchronous intermittent mandatory ventilation and continuous positive airway pressure. (5/415)

OBJECTIVE: To compare the effect of continuous positive airway pressure (CPAP) with synchronous intermittent mandatory ventilation (SIMV) during weaning, by measurement of the pressure time product (PTP). The PTP is an estimate of the metabolic work or oxygen consumption of the respiratory muscles. PATIENTS: Forty children, median age 14 months (range 1 month to 17 years) were studied immediately prior to extubation. METHODS: The PTP, derived from airway pressure changes, was measured while the child received SIMV (with or without pressure support) and then CPAP. A pneumotachograph was placed between the endotracheal tube and ventilator circuit. Its flow signal was used to indicate the beginning and end of inspiration. Airway pressure was measured from the pneumotachograph and the area subtended by the pressure curve (PTP) calculated using a modified Labview programme. RESULTS: The median PTP was significantly lower on SIMV (17.1 cm H(2)O/sec/min, range 0.4 to 60. 5) compared to on CPAP (32.6 cm H(2)O/sec/min, range 0.1 to 116.7), p < 0.001. CONCLUSION: These results suggest SIMV, rather than CPAP, may be the more efficacious weaning mode in children, and that the time spent on CPAP during weaning should be minimised.  (+info)

Respiratory effects of dexmedetomidine in the surgical patient requiring intensive care. (6/415)

STATEMENT OF FINDINGS: The respiratory effects of dexmedetomidine were retrospectively examined in 33 postsurgical patients involved in a randomised, placebo-controlled trial after extubation in the intensive care unit (ICU). Morphine requirements were reduced by over 50% in patients receiving dexmedetomidine. There were no differences in respiratory rates, oxygen saturations, arterial pH and arterial partial carbon dioxide tension (PaCO2) between the groups. Interestingly the arterial partial oxygen tension (PaO2) : fractional inspired oxygen (FIO2) ratios were statistically significantly higher in the dexmedetomidine group. Dexmedetomidine provides important postsurgical analgesia and appears to have no clinically important adverse effects on respiration in the surgical patient who requires intensive care.  (+info)

Weaning from mechanical ventilation. (7/415)

Practice guidelines on weaning should be based on the results of several well-designed randomized studies performed over the last decade. One of those studies demonstrated that immediate extubation after successful trials of spontaneous breathing expedites weaning and reduces the duration of mechanical ventilation as compared with a more gradual discontinuation of ventilatory support. Two other studies showed that the ability to breathe spontaneously can be adequately tested by performing a trial with either T-tube or pressure support of 7 cmH2O lasting either 30 or 120 min. In patients with unsuccessful weaning trials, a gradual withdrawal for mechanical ventilation can be attempted while factors responsible for the ventilatory dependence are corrected. Two randomized studies found that, in difficult-to-wean patients, synchronized intermittent mandatory ventilation (SIMV) is the most ineffective [corrected] method of weaning.  (+info)

Carbon dioxide kinetics and capnography during critical care. (8/415)

Greater understanding of the pathophysiology of carbon dioxide kinetics during steady and nonsteady state should improve, we believe, clinical care during intensive care treatment. Capnography and the measurement of end-tidal partial pressure of carbon dioxide (PETCO2) will gradually be augmented by relatively new measurement methodology, including the volume of carbon dioxide exhaled per breath (VCO2,br) and average alveolar expired PCO2. Future directions include the study of oxygen kinetics.  (+info)

Objectives: To compare and to analyze whether the values of rapid shallow breathing index (RSBI) determined by a ventilator display and a digital ventilometer were correlated. Methods: Twenty-two adult patients (17 males and 5 females) in the postoperative period of cardiac surgery and in mechanical ventilation were studied. Prior to the data collection, each patient was evaluated, received physical therapy, in order to promote bronchial hygiene and pulmonary reexpansion, and was positioned in elevated dorsal recumbent at 45°. After these procedures, minute ventilation (MV) and respiratory rate (RR) obtained from mechanical ventilator display and digital ventilometer were recorded. The RSBI was calculated by the ratio of RR and tidal volume (VT). Paired t-test was used to compare related variables. The intra-class correlation coefficients (ICCs) were used to measure the reproducibility of the scores. Results: A significant difference was found between the RSBI obtained from the ventilator and ...

The primary endpoint of this study will be the reduction in the days spent on MV. Other outcomes measured will be mortality, extubation and success rate, time to weaning of MV, length of ICU stay and incidence of tracheostomy. ...
Post-extubation respiratory failure causes between 5-30% of patients to require reintubation, which is associated with increased mortality. Spontaneous breathing trials aim to evaluate when a patient is ready for extubation and involves a trial of T-tube, low level pressure support or continuous positive airway pressure for varying durations ranging from 30 to 120 minutes. It was hypothesised that a rest period after a spontaneous breathing trial will improve extubation rates.. Method. A parallel, two-arm, prospective, randomised controlled trial in 17 Spanish Medical-Surgical ICUs aimed to test this hypothesis. From October 2013 to January 2015, 470 mechanically ventilated patients who had been receiving Mechanical Ventilation for at least 12 hours were enrolled.. If spontaneous breathing trial (SBT) was successful they were either extubated immediately (Control group) or reconnected to the ventilator with the previous ventilator parameters for 1 hour of rest and then extubated (Rest ...
Among 60 patients, 29 cases developed respiratory failure within 48 h, and 14 cases were re-intubated or died within 1 week, respectively. Multivariate logistic regression analysis showed that E/Ea (average) after SBT [odds ratio (OR) 1.450, 95% confidence intervals (CI) 1.092-1.926, P = 0.01] and left ventricular ejection fraction were associated with respiratory failure. The AUC of E/Ea (average) after SBT was 0.789, and a cut-off value ≥ 12.5 showed the highest diagnostic accuracy with a sensitivity and specificity of 72.4% and 77.4%, respectively. Furthermore, in the respiratory failure subgroup only DE (average) after SBT was associated with re-intubation (OR 0.690, CI 0.499-0.953, P = 0.024). The AUC of DE (average) after SBT was 0.805, and a cut-off value ≤ 12.6 mm showed the highest diagnostic accuracy with a sensitivity and specificity of 80% and 68.4%, respectively.. CONCLUSIONS ...

Unnecessary delays in removing patients from mechanical ventilation increase morbidity, mortality, and cost. According to recently published guidelines, the current standard of care for weaning involves the daily assessment of patients while they are breathing spontaneously, also known as spontaneous breathing trials (SBT). While there are important data to support a daily cessation of sedatives and analgesics to the point of patient awakening, the benefit of combining such a daily spontaneous awakening trial (SAT) and an SBT is not known.. This multi-center, randomized controlled trial will test whether a 2-step process of weaning that combines a daily awakening trial (achieved by stopping all sedatives and narcotics every morning) with a daily spontaneous breathing trial is superior to the current standard of care.. The number of days the patient is able to live off the ventilator is the primary question being studied. The secondary questions include the number of days the patient is in ...
With that clarification out of the way its time for me to update an old post which summarized recommendations on this topic. That post presented an evidence based method for daily extubation assessment of mechanically ventilated patients, focusing on the spontaneous breathing trial (SBT). Although I stand by the premise of that post it needs updating in light of this study which looked at integrating the daily SBT with a daily spontaneous awakening trial (SAT) as a protocol. Given that daily SATs (sedation interruptions) and SBTs are commonplace (or should be) in mechanically ventilated patients whats so new and different about this? I dont know for sure, but when those two procedures were organized in the form of an explicit protocol they out performed usual care in several metrics including mortality (NNT=7!). So what was usual care? Surprisingly it looked pretty evidence based---it employed the daily spontaneous breathing trial. But, apparently, in the usual care group, given that the SATs ...

An interesting study by Tulaimat and Mokhlesi1 regarding the accuracy and reliability of extubation decisions that recently appeared in the Journal merits additional comment. The implicit study question is whether an informed decision to extubate following a successful spontaneous breathing trial is any better than random chance. By study design, the clinical vignettes were selected so that, if a decision to extubate was made by coin flip, without any clinical information, the sensitivity and specificity (as defined in the study) would be expected to reach 50%. It was disappointing that, overall, experienced clinicians performed marginally better than a coin flip in predicting extubation success (ie, 57% sensitivity), but they were highly inaccurate in predicting weaning failure (ie, 31% specificity).. In a post hoc analysis, clinicians whose extubation decision-making was relatively aggressive achieved a higher sensitivity (62%), whereas clinicians whose extubation decision-making was ...
BACKGROUND: The quest to obtain an accurate way to predict success when weaning a patient from mechanical ventilation continues. The established parameters such as tidal volume (Vt), respiratory rate (f), negative inspiratory force (NIF), vital capacity (VC), and minute ventilation (V) have not predicted weaning accurately. The frequency-to-tidal volume ratio (f/Vt), or rapid shallow breathing index (RSBI) is a good predictor of weaning success if the value is low, but not when the value approximates 105. Because of the aforementioned, we decided to add 2 corrective factors to the RSBI. The first one was elastance index (EI = peak pressure/NIF) and the second one, the ventilatory demand index (VDI = minute ventilation/10). The result of the product of the RSBI × EI × VDI was called the weaning index (WI).. METHODS: In order to assess the discriminatory power of WI, we obtained weaning parameters and calculated WI for 59 patients in our intensive care unit and extubated them if RSBI was ≤105. ...
Twenty four patients were included, the following data were assessed: spontaneous respiratory frequency [/], spontaneous tidal volume [VT], peak inspiratory pressure [PIP], plateau airway pressure [P plat], maximum inspiratory pressure [PImax], rapid shallow breathing index [RSBI], dynamic compliance [Cdyn], static compliance [Cst], alveolar-arterial oxygen gradient [[A-a] O [2] and], minute ventilation [VE], shunt fraction and arterial to inspired oxygen ratio [PaO [2] /FIO2]. Eighteen patients were successfully weaned [GI] and six failed the T-piece trial [Gil]. Significant differences were found between both groups as regards RSBI, Cst, Cdyn, shunt fraction, p [A-a] O [2] Pplat and PaO2/FIO [2] [ ...

During the past year, 17 scientific publications, 3 case reports, 6 editorials, and 8 reviews were published, for a total of 33 papers on PubMed.. ADULT studies:. 1. NAVA vs. PAV vs. PSV in difficult to wean patients. In seventeen difficult to wean adult patients, Akoumianaki et al. (Respir Physiol & Neurobiology) compared physiologic parameters (Edi, Pes, Pdi, breathing pattern and arterial blood gases) during two 20-min periods of NAVA or PAV or PSV, without or with a respiratory challenge (added dead space or added load). The assist levels were set to obtain matching Pdi. Compared to PSV, both NAVA and PAV demonstrated proportionality between effort and VT, as well as improved variability in tidal volume. Trigger delays were significantly longer during PAV and PSV compared to NAVA.. 2. Patient-ventilator interaction in non-invasive ventilation (COPD). In the study of Doorduin et al (Crit Care), twelve COPD patients were ventilated with non-invasive NAVA (NIV-NAVA), PSV with a dedicated NIV ...
The value of an index for weaning from mechanical ventilation is its ability to predict respiratory endurance (1). Endurance reflects the ability of the respiratory capacity to meet the respiratory demands of resistive load from airways or endotracheal tube resistance, and elastic load from conditions that decrease compliance (e.g., fibrosis). Of the new indices that the authors present, the average VT and the ratio of respiratory frequency to tidal volume (f/VT) determined during a 1-minute bedside trial of spontaneous ventilation, are simple and warrant widespread consideration. 24 hours is a reasonable period of time to define successful liberation from mechanical ventilation but failures that occur shortly thereafter, often in less closely monitored environments, can have serious consequences. The f/VT index was the best predictor of successful weaning in this study. The usefulness of f/VT, however, should not eliminate careful systematic attention to other measurements that correlate ...

The first fundamental problem in weaning is deciding when to initiate the process. With widespread use of patient-assisted ventilatory modes, it is difficult to stipulate when mechanical ventilation changes from primary support to assistance in weaning. Nevertheless, delayed discontinuation of mechanical ventilation or repeated failed attempts at extubation could be avoided if there were criteria to predict weaning success or failure. The accuracy of these predictors of weaning outcome ( Table 2) are conflicting owing to differences in definitions, study methodologies, and cut-off values to separate success from failure. This is not surprising, given the many determinants of ventilator dependence. One proposed predictor, the ratio of frequency to tidal volume ( Yang„.a.nd..Tob.!0 1991), is simple to measure and is an index of rapid shallow breathing. Nonetheless, there is no consistent evidence to support the usefulness of any set of criteria to hasten the process of weaning ( Slutsky ...
If you starve yourself youre more likely to binge and not have energy to exercise.

In this group of patients a great number failed in the weaning process, showing, as expected, a higher mortality rate. Parameters most related to failure in the literature were higher age, longer length of ICU stay, mortality and f/VT. In this study, just the last parameter was sensitive principally in the 30th minute, and higher increase in f/VT (Δf/VT) during the test, demonstrating that patients with cardiac disease not fail more than others during the weaning process, as well as the efficiency of the test to predict success in weaning..

The authors didnt report the standard deviation (SD) for the primary outcome, the duration of mechanical ventilation, so we cant calculate a 95% confidence interval for the difference. (An aside: I know the authors of this trial and Im surprised they didnt report the 95% CI for the difference. I could estimate the SD from their Figure 2, if the data were normally distributed, but the distribution is highly skewed, so I dont want to commit a foundational error there.) A proportional outcome, the percentage successfully extubated was about 75% in each group and we dont need a SD for a proportion. The 95% CI for the difference in these proportions with 150 patients in each group is approximately -10% to +10%. Whether this is good enough for us, to conclude that a difference in successful weaning of 10% in either direction is negligible, I dont know ...

Identifying patients who are ready for weaning and liberation from veno-venous extracorporeal membrane oxygenation (ECMO) is challenging in clinical practice. Compared to the several trials addressing the safety and efficacy of ECMO in severe ARDS [1,2,3,4], the body of literature regarding ECMO weaning is remarkably scarce. Therefore, this essential component of the management of patients on ECMO is highly variable and often lacks of a systematic approach [5], analogously to the weaning protocols and spontaneous breathing trials used for liberation from mechanical ventilation [6].. The trajectory from ECMO cannulation to lung recovery and ECMO decannulation consists in the transition from a phase in which ECMO is essential to meet the patients metabolic needs (i.e. metabolic oxygen consumption and CO2 production) to a phase in which the native lung function has recovered to satisfy completely the metabolic demands, even if with a degree of ventilatory support considered safe. In between ...
Initial RSBI was similar in Extubation Success and Extubation Failure groups (77.0 ± 4.8, 77.0 ± 4.8, p = ns). Nevertheless, RSBI tended to remain unchanged or decreased in the Extubation Success group; in contrast RSBI tended to increase in the Extubation Failure group because of either increased RR and/or decreased VT (p , 0.001 for mean percent change RSBI over time), indicating worsening of the respiratory pattern. Quantitatively, only 7/63 subjects of the Extubation Success group demonstrated increased RSBI ≥20% at any time during the SBT. In contrast, in the Extubation Failure group, RSBI increased in all subjects during the SBT, and eight of nine subjects demonstrated an increase greater than 20%. Thus, with a 2-h SBT the optimal threshold was a 20% increase (sensitivity = 89%, specificity = 89%). Similar results were obtained at 30 min (threshold = 5% increase). Percent change of RSBI predicted successful extubation even when initial values were ≥105.. ...
To find out which ventilation mode or method your patient is receiving, check the ventilator itself or the respiratory flow sheet. The mode depends on patient variables, including the indication for mechanical ventilation.. Modes include those that provide specific amounts of TV during inspiration, such as assist-control (A/C) and synchronized intermittent mandatory ventilation (SIMV); and those that provide a preset level of pressure during inspiration, such as pressure support ventilation (PSV) and airway pressure release ventilation. PSV allows spontaneously breathing patients to take their own amount of TV at their own rate. A/C and continuous mandatory ventilation provide a set TV at a set respiratory rate. SIMV delivers a set volume at a set rate, but lets patients initiate their own breaths in synchrony with the ventilator.. Some patients may receive adjuvant therapy, such as positive end-expiratory pressure (PEEP). With PEEP, a small amount of continuous pressure (generally from +5 to ...
Press Release issued Jan 13, 2015: Ventilator is a life supporting healthcare device which regulates breathing of a patient during his treatment. Ventilators are used in the condition of serious lung disease or in other conditions which result in improper working of respiratory system. Ventilators help the patient to breathe easily. On the basis of type of product, ventilators may be classified into critical care ventilators, neonatal ventilators and transport and portable ventilators. On the basis of delivery of oxygen into the lungs, ventilators are of two types such as positive pressure mechanical ventilators and negative pressure mechanical ventilators. Ventilators are used generally used in hospitals. However, in conditions where patient needs long term care facilities and require ventilators for the rest of their lives, the ventilators can be used at home.
Objective To assess current ventilation practices in newborn infants. Study design We conducted a 2-point cross-sectional study in 173 European neonatal intensive care units, including 535 infants (mean gestational age 28 weeks and birth weight 1024 g). Patient characteristics, ventilator settings, and measurements were collected bedside from endotracheally ventilated infants. Results A total of 457 (85%) patients were conventionally ventilated. Time cycled pressure-limited ventilation was used in 59% of these patients, most often combined with synchronized intermittent mandatory ventilation (51%). Newer conventional ventilation modes like volume targeted and pressure support ventilation were used in, respectively, 9% and 7% of the patients. The mean tidal volume, measured in 84% of the conventionally ventilated patients, was 5.7 +/- 2.3 ml/kg. The mean positive end-expiratory pressure was 4.5 +/- 1.1 cmH(2)O and rarely exceeded 7 cmH(2)O. Conclusions Time cycled pressure-limited ventilation is ...

A hospital bed supported on a wheeled base, and a ventilator supported on a wheeled cart and docked to the base of the bed, the combination of ventilator and bed capable of being rolled as a single unit. The ventilator cart includes a wheeled base, and supports connected to the base for supporting a ventilator, with the supports providing for selective raising and lowering of the ventilator. The hospital bed base is wheeled and has a generally Y-shaped base frame. The outspread arms of the Y-shaped base frame receive the ventilator cart so that the two may be docked together. The ventilator when docked to the hospital bed base falls within the footprint of the bed as projected downwardly onto the floor. A latch secures the ventilator to the bed base. A disabling switch disables the high/low function of the bed preventing the bed from being lowered downwardly onto the ventilator. A power supply mounted to the bed base provides for uninterrupted operation of the ventilator. A care cart docks to the foot
Medical ventilator is a mechanical ventilator, its a machine designed or intended to move breathable air into and out of the lungs, to provide breathing for a patient who is physically not able to breath. In ventilators the air supply is pneumatically packed a few times each moment to convey room-air, or in most cases, an air/oxygen mixture to the patient. If a turbine is used, the turbine pushes air through the ventilator, with a flow valve adjusting pressure to meet patient-specific parameters.. The cutting edge ventilators are modernized ventilator machines, in which patients can be ventilated with a bag valve mask, a simple had operated bag valve mask, a basic hand worked sack valve veil. Modern positive pressure ventilator consisting of straight forward structure of a compressible air reservoir or turbine, air and oxygen supplies a set of valves and tubes, and a disposable or reusable patient circuit..

As soon as able wean the rate in steps of 5 breaths. Provided the patient is triggering breaths at or above the set rate then all you will be doing is swapping a big breath with a guaranteed Ti and tidal volume/Pressure for a smaller Pressure Support breath.. Once you have reached a rate of 5 breaths per minute the next step is to switch the patient to PS CPAP (the patient will already be mostly on PS CPAP as only 5 of their breaths will be big breaths and all other breaths will be PS breaths. When switching to PS CPAP, keep the pressure support and PEEP set the same as it was on the previous mode.. Wean the PS in steps of 2 till a pressure of 6 cmH2O is reached. Wean PEEP to 6 cmH2O. If the patient is stable on PS CPAP ON 6/6 (peak pressure of 12) and there are no contraindications a trial of extubation can be considered..

An Oscillating Ventilator is a very specialized high frequency ventilator that delivers breaths much faster than a conventional ventilator. Conventional ventilators may deliver about 20 to 60 breaths per minute, but an oscillating ventilator can deliver close to 1,000 breaths per minute. That may seem like a lot but very small or very sick premature babies have lungs that are easily damaged. The bigger slower breaths provided by a conventional ventilator can actually damage a sick newborns lungs and cause health conditions such a chronic lung disease..

And after about two weeks of getting prepared to make the switch, our Pedi tells me that my medication is perfectly safe while breastfeeding. I was so angry. Beyond angry. By then, he had adjusted to the bottle and I thought he was going to have a hard time coming back to the boob. Not my baby. He was so happy to be back. I could feel how relaxed he would get, he just sunk right in to my ...

  • Rate of reintubation in mechanically ventilated neurosurgical and neurologic patients: evaluation of a systematic approach to weaning and extubation. (
  • Patients who have low levels of adrenal are supposed to be weaned off early from ICU if they are given a supplement of hydrocortisone before extubation is attempted. (
  • Among the 20 patients with adequate adrenal reserves, 20 of 20 patients were taken off ventilator, but three failed after extubation . (
  • In addition, the investigators were wise to survey the intensivists who staff this ICU on their perceptions of the nurse-managed weaning protocol since they ultimately gave the "green light" to proceed with extubation. (
  • Thus, liberating the patient from the ventilator and removing the endotracheal tube (extubation) as soon as it is safe to do so are of extreme importance. (
  • 1 Choosing the appropriate time for weaning a patient from mechanical ventilation and extubation is crucial for reducing the risks of prolonged ventilatory support and premature weaning. (
  • Although no clear winner has emerged in the search for an optimal drug to facilitate extubation in the ICU, there is a strong consensus on the need for such weaning. (
  • An editorial written by him was published in the American Journal of Respiratory and Critical Care Medicine in 2012 titled, "Extubation and the myth of minimal ventilator settings. (
  • Our objective is to compare mechanical ventilation times, weaning success up to 48 hours after extubation, re-intubation rates between a group with computer driven weaning protocol (SmartCare) versus a weaning protocol with daily weaning screens and spontaneous breathing trials in ICU patients ventilated for more than 24 hours. (
  • MV and weaning time, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), vital capacity (VC), respiratory frequency to tidal volume ration (f/Vt), use of non-invasive ventilation (NIV) post extubation, and re-intubation rate we evaluated. (
  • The aim of this study was to assess the usefulness of noninvasive ventilation (NIV) as a systematic extubation and weaning technique to reduce the duration of ETMV in acute-on-chronic respiratory failure (ACRF). (
  • Conventional invasive pressure support ventilation (IPSV) was used as the control weaning technique in 16 patients (IPSV group), and NIV was applied immediately after extubation in 17 patients (NIV group). (
  • They are proposed as an alternative to nasal continuous positive airway pressure (NCPAP) in a variety of clinical situations, including post-extubation support, primary therapy from birth and 'weaning' from NCPAP. (
  • Twenty patients randomly received immediate NIV after early extubation or conventional weaning. (
  • Search themes will include: (1) BNP and (2) weaning, extubation and/or liberation from MV. Citation screening, selection, quality assessment and data abstraction will be performed in duplicate. (
  • Closed-loop modes and automated weaning procedures aim to set the most appropriate supporting pressure levels for the patient and promote early extubation, with conflicting results [ 5 - 8 ]. (
  • Mechanically ventilated patients should have a daily assessment relating to their ability to be weaned from ventilatory support. (
  • If the patient can maintain gas exchange at minimal levels of pressure support (usually 5 to 10 cm H2O) or when on the T-piece, the feasibility of weaning from mechanical ventilatory support can be assessed. (
  • Of the 76% of intensivists who completed the survey, their responses overall were a positive attitude toward the nurse-managed weaning protocol, including the earlier identification of patients ready to wean and the reduction in length of ventilatory support. (
  • The article by Danckers and colleagues reports on an innovative protocol that utilized the expertise of the ICU nursing staff to realize positive clinical outcomes for patients weaning from mechanical ventilatory support. (
  • Weaning can also be carried out by a process of progressive withdrawal in which ventilatory support is gradually withdrawn. (
  • Difficulty weaning from mechanical ventilation can be defined as failure to tolerate SBTs or failure to tolerate more systematic reduction in the level of ventilatory support. (
  • Weaning studies focus on finding methods to monitor and predict the outcome of mechanical ventilator weaning as well as finding ventilatory support techniques which will facilitate successful weaning. (
  • 10 , 15 , 16 Weaning patients from ventilatory support is a complex issue. (
  • In the present study, it was speculated whether the administration of low doses of glucocorticoids to patients with severe ventilator-associated pneumonia (VAP) would improve outcome in terms of increased survival and enhanced weaning from ventilatory support, and reduction of the severity of system organ dysfunction. (
  • In conclusion, NIV permits earlier removal of the endotracheal tube than with conventional IPSV, and reduces the duration of daily ventilatory support without increasing the risk of weaning failures. (
  • Our ventilator teams consist of board-certified pulmonologists, pulmonary program managers, advanced practice nurses, respiratory therapists, nursing and rehabilitation professionals, pharmacists and nutritionists. (
  • The two weaning groups were similar for type of chronic respiratory failure (CRF), pulmonary function data, age, Simplified Acute Physiology Score (SAPS II), and severity of ACRF on admission. (
  • Diagnostic efficacy of serum procalcitonin, C-reactive protein concentration and clinical pulmonary infection score in Ventilator-Associated Pneumonia. (
  • The aim of this study was to evaluate the diagnostic efficacy of serum procalcitonin (PCT), c-reactive protein (CRP) concentration and clinical pulmonary infection score(CPIS) in ventilator-associated. (
  • Lung damage that is caused by the adverse effects of PULMONARY VENTILATOR usage. (
  • The high frequency and tidal volumes produced by a mechanical ventilator can cause alveolar disruption and PULMONARY EDEMA. (
  • The aim of the present randomised controlled study was to test the hypothesis that weaning with ASV could reduce the weaning duration in patients with chronic obstructive pulmonary disease (COPD) when compared with PSV. (
  • Patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) often require either noninvasive mechanical ventilation (NIMV) or invasive mechanical ventilation (IMV) and prolonged weaning times [ 1 ]. (
  • These patients also experience more pulmonary complications and have more difficulty weaning from ventilation. (
  • On average, 70 percent of patients unable to breathe on their own in a traditional hospital are successfully weaned from a mechanical ventilator through our resource-intensive pulmonary program. (
  • Failure to recognize ventilator withdrawal potential may result in increased time on mechanical ventilation, length of stay, risk of complications such as ventilator associated pneumonia (VAP), mortality, and costs. (
  • The effect of reintubation on ventilator-associated pneumonia and mortality among mechanically ventilated patients with intubation: A systematic review and meta-analysis. (
  • Ventilator-associated pneumonia (VAP) is a relatively common complication in patients who receive prolonged mechanical ventilation. (
  • Incidence of and risk factors for ventilator-associated pneumonia in critically ill patients. (
  • Main outcomes for comparison included duration of mechanical ventilation (days), ICU length of stay, ventilator-associated pneumonia (VAP) rates, hospital mortality, and physician attitudes toward the nurse-managed protocol. (
  • This is known as ventilator-associated pneumonia (VAP).It is a leading cause of death in critically ill patients and can also increase the length of hospital stay and healthcare costs. (
  • These patients tend to develop cough problems and consequently mucus retention, atelectasis and ventilator-associated pneumonia. (
  • However, it is associated with several complications, such as ventilator-associated pneumonia and the increase of hospital morbidity and mortality. (
  • The purpose of this study is to test a new method for diagnosing and monitoring Ventilator-Associated Pneumonia, which is a major killer among ICU patients. (
  • Her research interests include improving outcomes in the mechanically ventilated adult critically ill patient population, prevention of ventilator-associated pneumonia, and positional therapy as an adjunct treatment for acute respiratory distress syndrome. (
  • One track is for patients who have the possibility of being weaned or who are difficult to wean and a second track is designed for patients that cannot be weaned and who will be cared for at home. (
  • Patients suffering from VIDD are more difficult to wean from the ventilator. (
  • NIV should be considered as a new and useful systematic approach to weaning in patients with ACRF who are difficult to wean. (
  • Efficacy and safety of a paired sedation and ventilator weaning protocol for mechanically ventilated patients in intensive care (Awakening and Breathing Controlled trial): a randomised controlled trial. (
  • Purpose of review: Guidelines for weaning from sedation and weaning from ventilator gained increasing interest in recent years. (
  • Gentle non-invasive ventilation (NIV) reduces the need for patient sedation and a separate NIV ventilator. (
  • Patients should be assessed daily for their readiness to be weaned from mechanical ventilation by withdrawing sedation and performing a spontaneous breathing trial. (
  • Recently, an argument has developed as to which weaning protocol would be more appropriated, and whether a computer driven weaning protocol could have better results than the conventional weaning protocols focusing on daily screening and daily interruption of sedation followed by a spontaneous breathing test. (

  • Using a new classification of weaning this group includes patients with difficult weaning (patient takes up to three SBTs or up to seven days from first SBT to be successfully extubated) and prolonged weaning (patient fails at least three SBTs or requires more than 7 days from the first SBT to be successfully extubated). (
  • This should be distinguished from simple weaning, where the patient tolerates the initial SBT and is successfully extubated. (
  • A patient with a rapid shallow breathing index (RSBI) of less than 105 has an approximately 80% chance of being successfully extubated, whereas an RSBI of greater than 105 virtually guarantees weaning failure. (
  • In the IPSV group, 12 of 16 patients (75%) were successfully weaned and extubated, versus 13 of 17 (76.5%) in the NIV group (p = NS). (
  • INTRODUCTION: Physiological determinants of weaning success and failure are usually studied in ventilator-supported patients, comparing those who failed a trial of spontaneous breathing with those who tolerated such a trial and were successfully extubated. (
  • Time to initiation of weaning trials was 2 ICU days in the nurse-driven protocol group, whereas it was 3 days in the physician group. (
  • Recently there has been an increased interest in automatic weaning trials, which consists of closed-loop ventilation, using ETCO2 monitoring during SBT [1, 2]. (

  • Implementation of a nurse-driven protocol for weaning patients resulted in shortened duration of mechanical ventilation, shorter ICU stays, and a higher rate of successful weaning, with ICU physicians reporting a generally positive attitude toward nurses being responsible for protocol-directed weaning. (
  • It is also associated with numerous complications that prolong the duration of time spent on the ventilator and increases mortality. (
  • METHODS: In 30 stable tracheotomised ventilator-dependent patients admitted to a weaning center inside a respiratory intensive care unit, we recorded the breathing pattern, respiratory mechanics, inspiratory muscle function, and tension-time index of diaphragm (TTdi = Pdisw/Pdimax [that is, tidal transdiaphragmatic pressure over maximum transdiaphragmatic pressure] x Ti/Ttot [that is, the inspiratory time over the total breath duration]) at the time of weaning failure (T0).

  • It, however, depends on whether their chest X-Ray is clear, if they are oxygenating their blood and vital organs, and if they can breathe by themselves with little support from the respirator/ventilator. (
  • Recognition of readiness for spontaneous breathing followed by timely SBTs, lasting from 30 to 120 minutes, and conducted on T-piece, CPAP, or low levels of pressure support (with or without automatic tube compensation), has become the preferred method of weaning. (
  • There are many different medical conditions that may require a patient to rely on a ventilator, for breathing assistance or life support, for a period of time. (
  • If a patient is receiving mechanical ventilator support using Airway Pressure Release Ventilation (APRV) or a related type of mechanical ventilation intermittently (that is, for less than an entire calendar day), how do I determine the daily minimum FiO2 and PEEP values? (
  • Some patients who are on the ventilator for an extended period of time may be on CPAP during the day, will full ventilator support at night so they can fully rest and continue to heal without being exhausted by the work of breathing. (
  • Servo ventilators allow you to detect risks early and support with timely and consistent implementation of your personalized ventilation strategies. (
  • The method of choice is minimal ventilator settings, such as a Peep of 5 and a Pressure Support (PS) of 10. (
  • The expression "minimal ventilator settings" has become a commonplace, suggesting that pressure support of 5 cm H2O or CPAP 5 cm H2O provides little assistance to a patient. (
  • If you create a situation from them where they have to work a little (such as would be the case breathing through the ETT with no support from the ventilator), and they do not fail, then you can feel pretty safe that patient won't require re-intubation. (
  • The Control group consisted of a daily weaning screen and SBT with pressure support ventilation. (
  • 2 ] compared short-term patient-ventilator interaction during NIV with pressure support (PS) and neurally adjusted ventilatory assist (NAVA). (

  • In patients with severe respiratory failure, either hypoxemic or hypercapnic, life support with mechanical ventilation alone can be insufficient to meet their needs, especially if one tries to avoid ventilator settings that can cause injury to the lungs. (
  • After that trial, a group in Italy 11 published their experience using ECMO support in 43 patients, in whom high positive end-expiratory pressure (PEEP) values (15-25 cmH 2 O), together with what they considered low peak pressures (35-45 cmH 2 O) and low RR (3-5 breaths/min), were applied with the rationale of reducing the lung injury caused by the ventilator. (
  • 2,3 If he or she passes the screen, you may consider adjusting the ventilator to provide no or reduced breathing support (less than 7 cmH 2 O inspiratory pressure), for example, via pressure support, continuous positive airway pressure (CPAP) or ventilation with a T-piece. (

  • We studied eleven patients during 14 attempts at weaning from mechanical ventilation to determine whether central ventilatory drive, measured as airway occlusion pressure 0.1 s after onset of inspiration (P 0.1 ), during spontaneous breathing before and during a brief hypercapnic challenge, could accurately predict the success or failure of the attempt. (
  • All patients were recovering from acute respiratory failure and could breath spontaneously for 20 minutes on a T-piece but were judged clinically to be marginal weaning candidates. (

  • Josh went into respiratory failure as a result of Graft versus host disease (GVHD) and was intubated and placed on a ventilator. (
  • The ventilator gently pushes air into the lungs and allows it to come back out, like the lungs would typically do when they are able. (
  • This is done because it can be upsetting and irritating to the patient to have an endotracheal tube in place and feel the ventilator pushing air into the lungs. (
  • The diagnostic effort is then extended to identify the underlying pathophysiologic cause for difficulty weaning from mechanical ventilation. (
  • The first is identifying the patients with difficulty weaning from mechanical ventilation. (
  • The second component is identifying why the patient is having difficulty weaning from mechanical ventilation. (
  • Mechanical ventilation is expensive and ventilator-associated complications can further increase the costs dramatically. (
  • It is however noteworthy that being weaned off a ventilator after 72 hours is a bit more difficult because the longer ventilation pressures and controlled breathing make the risk of complications higher. (
  • Background: Noninvasive ventilation has been studied as a means of reducing complications among patients being weaned from invasive mechanical ventilation. (
  • To avoid such complications, we need to wean these patients off the ventilator as soon as possible. (
  • For this reason, it is important to have a specific weaning protocol, which will reduce the time on mechanical ventilation, and avoiding the need for re-intubation and other complications. (

  • The present expansion study showed that, through simple bedside physical examinations, rehabilitation physicians could relatively easily predict diaphragm movement and respiratory function recovery, which showed significance with ventilator weaning in patients with high cervical SCI. (
  • CONCLUSIONS: The recovery of an inadequate inspiratory muscle force could be the major determinant of 'late' weaning success, since this allows the patients to breathe far below the diaphragm fatigue threshold. (
  • Since managing the protocol includes making changes to ventilator settings, he believes RTs are the safest clinicians to implement it as well. (
  • By applying it clinically, clinicians can select the earliest appropriate weaning time. (
  • Ventilation increased more during hypercapnic challenge in those patients whose weaning attempt was successful, but overlap of results between the two groups rendered this test inaccurate for predicting weaning success. (

  • Therefore, if a patient that is critically ill is stable and has the strength to breathe on their own, then there is no reason why they can't be taken off the ventilator after about a week. (
  • A ventilator, also known as a respirator or breathing machine, is a medical device that provides a patient with oxygen when they are unable to breathe on their own. (
  • There are also times when a ventilator is required after surgery, as the patient may not be able to breathe on their own immediately after the procedure. (
  • Once the anesthesia stops, the patient is able to breathe on their own and they are removed from the ventilator. (
  • A ventilator is necessary when the patient is unable to breathe well enough to provide oxygen to the brain and body. (
  • Some patients, due to injury or illness, cannot breathe well enough after surgery to be removed from the ventilator. (
  • A patient who is on the ventilator prior to surgery will likely remain on the ventilator after surgery until they recover enough to breathe well on their own. (
  • They are not given a drug to stop the anesthesia, rather it is allowed to wear off on its own, and the patient is removed from the ventilator when they are ready to breathe on their own. (
  • The goal is to keep the patient calm and comfortable without sedating them so much that they cannot breathe on their own and be removed from the ventilator. (
  • Patients who are not able to be removed from the ventilator immediately after surgery may require weaning, which is a process where the ventilator settings are adjusted to allow the patient to attempt to breathe on their own, or for the ventilator to do less work and the patient to do more. (
  • People on a ventilator who cannot tolerate independent breathing tend to breathe rapidly (high frequency) and shallowly (low tidal volume), and will therefore have a high RSBI. (
  • Patients are usually placed on ventilators when a condition makes it difficult for them to breathe on their own. (
  • The ventilator helps a person to breathe so his or her body can rest and heal. (

  • Equally important is communication with the bedside team at large to ensure that everyone is aware of the patient's progress or current status related to their ventilator liberation progress," Haas said. (
  • This process of liberation has been termed "weaning" and encompasses all efforts to free the patient from the ventilator. (
  • Our current policy, based on studies from about ten years ago, suggests that minimal ventilator settings are ideal to make up for resistance of the tubing and physiologic PEEP. (
