During spontaneous breathing trial, low-pressure support is thought to compensate for endotracheal tube resistance, but it actually should provide overassistance. Automatic tube compensation is an option available in the ventilator to compensate for flow-resistance of endotracheal tube. Its effects on patient effort have been poorly investigated. We aimed to compare the effects of low-pressure support and automatic tube compensation during spontaneous breathing trial on breathing power and lung ventilation distribution. We performed a randomized crossover study in 20 patients ready to wean. Each patient received both methods for 30 min separated by baseline ventilation: pressure support 0 cmH2O and automatic tube compensation 100% in one period and pressure support 7 cmH2O without automatic tube compensation in the other period, a 4 cmH2O positive end-expiratory pressure being applied in each. Same ventilator brand (Evita XL, Draeger, Germany) was used. Breathing power was assessed from Campbell diagram

BackgroundMechanical ventilation causes ventilator-induced lung injury in animals and humans. Mitogen-activated protein kinases have been implicated in ventilator-induced lung injury though their functional significance remains incomplete. We characterize the role of p38 mitogen-activated protein kinase/mitogen activated protein kinase kinase-3 and c-Jun-NH2-terminal kinase-1 in ventilator-induced lung injury and investigate novel independent mechanisms contributing to lung injury during mechanical ventilation.Methodology and Principle FindingsC57/BL6 wild-type mice and mice genetically deleted for mitogen-activated protein kinase kinase-3 (mkk-3−/−) or c-Jun-NH2-terminal kinase-1 (jnk1−/−) were ventilated, and lung injury parameters were assessed. We demonstrate that mkk3−/− or jnk1−/− mice displayed significantly reduced inflammatory lung injury and apoptosis relative to wild-type mice. Since jnk1−/− mice were highly resistant to ventilator-induced lung injury, we performed

Ventilator-associated lung injury (VALI) is an acute lung injury that develops during mechanical ventilation and is termed ventilator-induced lung injury (VILI) if it can be proven that the mechanical ventilation caused the acute lung injury. In contrast, ventilator-associated lung injury (VALI) exists if the cause cannot be proven. VALI is the appropriate term in most situations because it is virtually impossible to prove what actually caused the lung injury in the hospital. It is generally regarded, based on animal models and human studies, that volutrauma is the most harmful aspect of mechanical ventilation. This may be regarded as the over-stretching of the airways and alveoli. During mechanical ventilation, the flow of gas into the lung will take the path of least resistance. Areas of the lung that are collapsed (atelectasis) or filled with secretions will be underinflated, while those areas that are relatively normal will be overinflated. These areas will become over distended and injured. ...

Objective To investigate whether tracheostomy placement in infants requiring high ventilator pressure is safe and effective. Study Design Case series with chart review. Setting Tertiary childrens hospital. Methods Fifty ventilator-dependent neonatal intensive care unit patients who underwent tracheotomy from 2009 to 2018 were included. Patients requiring high ventilator pressures were compared to those requiring low ventilator pressures. Demographics, comorbidities, and surgical and clinical data were recorded. Results Thirty-two percent (n = 16) had low ventilator settings at the time of tracheostomy tube placement, and 68% (n = 34) had high ventilator settings. The median peak inspiratory pressure of the high ventilator group was 29.5 cm H2O, positive end-expiratory pressure (PEEP) was 8 cm H2O, mean airway pressure was 13 cm H2O, pressure support (PS) was 14 cm H2O, PS above PEEP was 6 cm H2O, and inspiratory time was 0.65 seconds. The high ventilator cohort had a higher median age at the time of

BACKGROUND Aerosolized medications that have been used in infants receiving ventilatory support have not been shown to be effective clinically among the smallest patients.

Background: Ventilator-associated pneumonia is a major cause of morbidity and mortality for patients in an intensive care unit. Once present, ventilator-associated pneumonia is known to increase the duration of mechanical ventilation, time in the intensive care unit, and length of hospital stay. Patients with acquired brain injury are commonly admitted to the intensive care unit and considered to be at a high risk for the development of respiratory complications such as ventilator-associated pneumonia, which could potentially impact on the intensive care unit costs and outcomes. Respiratory physiotherapy is often provided to prevent and/or treat ventilator-associated pneumonia in patients with acquired brain injury. The theoretical rationale of the respiratory physiotherapy is to improve airway clearance and enhance ventilation which may reduce the incidence of pulmonary infections and thus ventilator-associated pneumonia, and may in turn decrease the duration of mechanical ventilation, prevent ...

A liquid ventilator is similar to a medical ventilator except that it should be able to ensure reliable total liquid ventilation with a breatheable liquid (a perfluorocarbon) · . Liquid ventilators are prototypes that may have been used for animal experimentations but experts recommend continued development of a liquid ventilator toward clinical applications. In total liquid ventilation (TLV), the lungs are completely filled with a perfluorocarbon (PFC) liquid while the liquid ventilator renews the tidal volume of PFC. The liquid ventilator operates in mandatory mode: it must force the PFC in and out of the lungs with a pumping system. During the inspiratory phase, the pump generates a positive driving pressure in the trachea to ensure the PFC insertion of the tidal volume. During the expiratory phase, the pump generates a negative driving pressure in the trachea to ensure PFC withdrawal of the tidal volume. The pumping system is either a peristaltic pump (in the simplest liquid ventilators) or ...

Mechanical ventilation (MV) can provoke oxidative stress and an inflammatory response, and subsequently cause ventilator-induced lung injury (VILI), a major cause of mortality and morbidity of patients in the intensive care unit. Inhaled hydrogen can act as an antioxidant and may be useful as a novel therapeutic gas. We hypothesized that, owing to its antioxidant and anti-inflammatory properties, inhaled hydrogen therapy could ameliorate VILI. VILI was generated in male C57BL6 mice by performing a tracheostomy and placing the mice on a mechanical ventilator (tidal volume of 30 ml/kg without positive end-expiratory pressure, FiO(2) 0.21). The mice were randomly assigned to treatment groups and subjected to VILI with delivery of either 2% nitrogen or 2% hydrogen in air. Sham animals were given same gas treatments for two hours (n = 8 for each group). The effects of VILI induced by less invasive and longer exposure to MV (tidal volume of 10 ml/kg, 5 hours, FiO(2) 0.21) were also investigated (n = 6 ...

INTRODUCTION: Ventilators possess an anti-asphyxia valve that allows spontaneous breathing of ambient air during ventilator failure. This study examined the imposed work of breathing and pressure-time product of 8 critical care and 9 portable ventilators, using a laboratory simulation of spontaneous breathing during ventilator failure. METHODS: A test lung was modified to simulate spontaneous breathing with a tidal volume of 0.5 L and peak inspiratory flow of 60 L/min. A pneumotachograph and pressure tap were placed at the proximal airway between the breathing circuit and endotracheal tube. Flow was derived from the pressure drop across the pneumotachograph. Signals were amplified, integrated, and saved to a spreadsheet program, and imposed work of breathing and pressure-time product were calculated. Also measured were the inspiratory pressure required to open the anti-asphyxia valve (cracking pressure), time to cracking pressure, maximum negative inspiratory pressure, and time to maximum ...

Mechanical stress induced by injurious ventilation leads to pro-inflammatory cytokine production and lung injury. The extracellular-signal-regulated-kinase, ERK1/2, participates in the signaling pathways activated upon mechanical stress in the lungs to promote the inflammatory response. Tumor progression locus 2 (Tpl2) is a MAP3kinase that activates ERK1/2 upon cytokine or TLR signaling, to induce pro-inflammatory cytokine production. The role of Tpl2 in lung inflammation, and specifically in the one caused by mechanical stress has not been investigated. The aim of the study was to examine if genetic or pharmacologic inhibition of Tpl2 could ameliorate ventilator-induced lung injury. Adult male wild-type and Tpl2-deficient mice were ventilated with normal or high tidal volume for 4 h. Additional wild-type mice were treated with a Tpl2 inhibitor either before or 30 min after initiation of high tidal ventilation. Non-ventilated mice of both genotypes served as controls. The development of lung injury was

Home Mechanical Ventilation in Europe started as tracheostomy ventilation in the late 1970s1; it remained under-utilized and restricted to specialized centres in France.. Due to the transition to non-invasive ventilator support, patients under Home Mechanical Ventilation (HMV) have grown worldwide.2. Indeed, HMV became widespread in Europe and a survey (Eurovent) presenting data from 2001 to 2002 in 16 European countries (including a total of 483 centres), showed a global prevalence of 6.6 per 100,000 with a wide variation between countries.3. In 2010, the European COPD audit (surveying 13 countries), showed that although a majority of centres offered invasive and noninvasive ventilation, 40.5% of centres declared not to have the capacity to ventilate at home all eligible patients.4. In fact, organization varies widely in Europe, in countries like Denmark, where patients are referred to only 2 respiratory care units (RCU)5 or Sweden where there are a wide number of outpatient clinics that take ...

Heat and moisture exchangers (HMEs) have been increasingly used for humidification during mechanical ventilation in pediatric patients [1]. However, efficacy of HMEs in the pediatric population has not yet been fully evaluated and there is limited information in the literature regarding the effects of ventilator settings and endotracheal tube (ETT) leakage on the humidification performance of HMEs.. Chikata et al. [2] tested ten pediatric HMEs in a model lung, measuring performance under different respiratory rates, tidal volumes TVs (achieved with different pressure control levels), and leakage conditions. They found that eight of the ten HMEs maintained absolute humidity (AH) at more than 30 mg/L, the minimum level recommended by the American Association for Respiratory Care (AARC). With a small leak, AH decreased below 30 mg/L (26.6 to 29.5 mg/L), decreasing further (19.7 to 27.3 mg/L) with a larger leak. Pressure control (tidal volume) level did not statistically significantly affect AH ...

Ventilator-associated pneumonia (VAP) in a critically ill patient significantly increases risk of mortality and, at a minimum, increases ventilator time, length of stay, and cost of care. It is a complex condition not only to diagnose but also to treat, thus prevention is extremely important. Many hospitals have achieved significant reductions in VAP rates in their critical care units, some even reaching zero by taking a comprehensive and multidisciplinary approach to ventilator care. The IHI Ventilator Bundle - a grouping of best practices that, when applied together, may result in substantially greater improvement - has been implemented in many ICUs, along with teamwork and communication strategies such as structured multidisciplinary rounds and daily goal setting, to wean and remove patients from ventilators as quickly as possible, while providing evidence-based care. ...

Acute lung injury patients on ventilators who require a feeding tube have a similar number of ventilator-free hospital days and similar mortality rates if they receive a low-calorie feeding program initially followed by a full-calorie program compared to a full-calorie program right away. These results are part of a new clinical study funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health.. The patients in the low-calorie, or delayed, feeding program received about 400 calories per day for the first six days before advancing to a full feeding program. The patients enrolled in the full feeding program were advanced as quickly as they could tolerate to a full daily calorie and protein goal based on weight (averaging about 1,300 calories per day).. The appropriate feeding protocol for mechanically ventilated patients is an important practical question that has been debated in intensive care units for decades, said Susan B. Shurin, M.D., acting ...

When hospital patients need assistance breathing and are placed on a mechanical ventilator for days at a time, their lungs react to the pressure generated by the ventilator with an out-of-control immune response that can lead to excessive inflammation, new research suggests.. While learning that lungs perceive the ventilation as an infection, researchers also discovered potential drug targets that might reduce the resulting inflammation - a tiny piece of RNA and two proteins that have roles in the immune response.. Using human cell cultures, Ohio State University researchers determined that mechanical pressures trigger an innate immune response - the same immune response that the body launches to begin its fight against any kind of infection.. The rhythmic pressure of ventilation stimulated the production of pro-inflammatory chemicals by activating proteins called toll-like receptors (TLRs) in lung cells, the research showed.. We showed that these cells respond to a mechanical force, pressure, ...

The rapid spread of SARS-CoV2 throughout the world has put an unimaginable strain on the healthcare system. Patients are at risk of facing the consequences of not enough ventilators, which in dealing with respiratory failure is fatal. This is a last resort, emergency-only device for use if ever faced with a critical shortage of ventilators. The concept of ventilator sharing to our knowledge was first written by Dr. Neyman and Dr. Irvin in 2006 (Ac Emergency Medicine 2006). They demonstrated that by using T-tubes and adapters, a ventilator circuit could be divided such that four simulated patients could share a single ventilator in emergency circumstances. Although only simulated in the original article, this technique was successfully used by Dr. Menes in the 2017 Las Vegas shooting mass casualty incident. This technique saved the lives of patients, buying time until more ventilators could arrive. Some hospitals do not have the T-tubes or other parts readily available to setup a ventilator for ...

The mechanisms by which conventional MV exacerbates lung injury and inflammation are of considerable clinical significance. Redox imbalance has been postulated, among other mechanisms, to enhance/perpetuate susceptibility to VILI. A better understanding of these pathologic mechanisms will help not only in alleviating the side effects of mechanical forces but also in the development of new therapeutic strategies.

Objective: Lung-recruited Ly6C monocytes had been shown to be involved in ventilator-induced lung injury (VILI). Our present study aimed to investigate whether the COX-2 inhibition modulates the function of lung-recruited Ly6C monocytes in a mouse model of VILI. Methods: Mice were exposed to lipopolysaccharide (LPS; 20 ng) intraperitoneally prior to injurious mechanical ventilation (Vt = 30 ml/kg, PEEP = 0 cmH2O). A subgroup of mice was treated with intravenous parecoxib (30 mg/kg), a COX-2 inhibitor, 1 hour prior to ventilation. Control mice received saline and were not ventilated. At the end of the experiment, blood gas analysis was performed and lung tissue was collected for histological assessment. Flow cytometry was employed to quantify the different populations of lung monocytes/macrophages and their function. Isolated Ly6C cells were used to measure the intracellular concentrations of reactive oxygen species (ROS) and nitric oxide (NO) by fluorescent probes, and cytokine production by ...

Patients under NIV for hypercapnic COPD have several reasons to develop patient-ventilatory asynchrony: delayed cycling, and insufficient expiratory time may induce progressive dynamic hyperinflation, and increase intrinsic positive end-expiratory pressure (PEEPi); too high levels of pressure support may also contribute to dynamic hyperinflation. Increase in PEEPi is associated with two respiratory events: unrewarded inspiratory efforts, and auto-triggering.. Our hypotheses are: 1/that these events occur frequently in COPD under NIV and that they are not detected by medical history or usual monitoring tools (SpO2; PtcCO2); 2/ that they can be easily detected by polysomnography; 3/ that simple adjustments of ventilator parameters aiming to reduce dynamic hyperinflation and unrewarded inspiratory efforts may improve efficacy of ventilation, quality of sleep and comfort of treatment.. The present study compares the results of two consecutive sleep studies: 1.PSG under NIV in severe stable COPD ...

Mechanical ventilation is an important life support treatment of critically ill patients, and air pressure dynamics of human lung affect ventilation treatment effects. In this paper, in order to obtain the influences of seven key parameters of mechanical ventilation system on the pressure dynamics of human lung, firstly, mechanical ventilation system was considered as a pure pneumatic system, and then its mathematical model was set up. Furthermore, to verify the mathematical model, a prototype mechanical ventilation system of a lung simulator was proposed for experimental study. Last, simulation and experimental studies on the air flow dynamic of the mechanical ventilation system were done, and then the pressure dynamic characteristics of the mechanical system were obtained. The study can be referred to in the pulmonary diagnostics, treatment, and design of various medical devices or diagnostic systems.

MONDAY, April 13, 2020 (HealthDay News) -- With a sudden need for more ventilators due to the coronavirus pandemic, researchers have been busy trying to come up with alternatives to a standard ventilator. Engineers from Georgia Tech and Emory University in Atlanta think they may have developed such a device. Theyve created a simple, low-cost ventilator that builds on the widely used resuscitation bags found in ambulances and emergency departments everywhere. The COVID-19 infection has an alarmingly high rate of respiratory distress associated with it, especially in certain vulnerable populations. The need for critical care beds, which are beds with ventilators, is acute, and health systems are not scaled up for the number of patients that will need mechanical ventilation support in this country and globally, explained Susan Margulies, chair of biomedical engineering at Georgia Tech and Emory University. Margulies said her team thought the fastest way to have an impact would be to look at ...

Ventilator-associated pneumonia in critically ill or injured adults is an important cause of morbidity and mortality. This well-designed study adds to the evidence suggesting that local antibiotic decontamination of the oropharynx decreases ventilator-associated pneumonia in high-risk patients. However, no benefit was reported for the clinically important measures of mortality, duration of mechanical ventilation, or intensive care unit stay. Whether this reflects a true lack of benefit or an inadequate number of study subjects cannot be determined without a larger study. The benefit of oropharyngeal decontamination was independent of systemic prophylactic or therapeutic antibiotic therapy given to some patients. Group inequality in pneumonia resulting from aspiration of nasogastric tube feedings appeared an unlikely source of bias, because feedings were administered to a similar proportion of patients in each group, and the investigators did not observe any clinically apparent episodes of ...

Introduction. In 1997 it was published a paper concerning the use of intravenously (IV) cefuroxime prophylaxis against nosocomial pneumonia in intubated patients with structural coma.1 This randomized clinical trial (RCT) studied two groups of patients: one of them were administered two doses of IV cefuroxime upon intubation, and the other were administered no antibiotic prophylaxis. A 52% reduction was observed in ventilator-associated pneumonia (VAP) and 56% if early-onset ventilator-associated pneumonia (EO-VAP) is considered in the IV cefuroxime prophylaxis group. Since then, several research groups worldwide have followed this clinical practice on intubated patients with structural coma upon intubation. Now, literature is reviewed to check whether this measure is still appropriate twenty years later, and some criticism is also made regarding the inclusion of this preventive measure into international recommendations and guidelines for infection control of intubated patients in intensive ...

This study by Vallés and colleagues is one of the few randomized controlled trials suggesting the effectiveness of a preventive measure for ventilator-associated pneumonia, and the second trial dealing with subglottic secretions drainage (1, 2). This trial shows that continuous aspiration may reduce the incidence of ventilator-associated pneumonia by almost half or delay its onset. Although investigators were not blinded to treatment allocation and an intention-to-treat analysis was not done, one strength of this study is that the diagnosis of pneumonia was ascertained using specific sampling techniques. Similar to the results of many studies of selective digestive tract decontamination, however, none of the major outcome measures of prophylaxis was affected by the maneuver. These results contradict those from epidemiologic studies that showed increased mortality or length of stay in patients with nosocomial pneumonia. This lack of effect of continuous aspiration on outcome may be related to ...

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 ...

The Atlantis is the only FDA 510(k) cleared hyperbaric ventilator on the market. Other manufacturers may claim or imply that their ventilators are 510(k) cleared for use with a hyperbaric chamber, but they are not. Before the Atlantis received 510(k) clearance and was available on the market, hyperbaric practitioners and manufacturers were forced to modify existing ventilators for use with hyperbaric chambers. The use of a non-FDA cleared ventilator creates several medical and legal issues for hyperbaric practitioners and administrators such as performance reliability, insurance carrier notification requirements, trouble complying with accreditation standards and the obligation to meet enhanced standards for informed patient consent. These medical and legal issues associated with using a non-FDA 510(k) cleared medical device disappear when the Atlantis ventilator is used with a hyperbaric chamber. The Atlantis comes with a three year factory warranty. This warranty is renewable for additional ...

Heat and moisture exchanger (HME) filters are replacing heated humidifiers (HH) to promote humidification of inhaled air during mechanical ventilation. The argument is often that the HMEs are related to a lower incidence of VAP. On the other hand, a restriction to HMEs is that they are associated with an increased incidence of obstruction of the endotracheal tube. It is now known that the ventilator circuit and its accessories, including the humidification system, have very little impact on the incidence of VAP. The aspiration of contaminated secretions is the main determinant of this complication. The objective of this study was to compare the incidence of VAP in patients undergoing mechanical ventilation using HH versus HME filter. Secondarily, we analyzed the incidence of tracheal tube obstruction in both groups. ...

摘要：Transformer breathing system is an important auxiliary equipment of the transformer. However, in the daily operation process, due to the accidental airway blockage and other accidents, the transformer will be injected and the trip will stop running. Therefore, the transformer respiratory system needs to be the key in operation and maintenance management. One of the links of concern. Based on the practical application of actual substation on-site operation and maintenance management, this paper designs a maintenance-free transformer breathing system and applies the Internet of Things technology to monitor the respiratory system online, improving the ability to grasp the state of the respiratory system and further improving the safety of the substation. Reduce the workload of inspections and reduce the operation and maintenance costs of substations.更多还原 ...

John: Cochrane has several systematic reviews about the management of patients in intensive care units, covering a wide range of interventions, and the update of one of these in October 2016 brought together the latest evidence on the effects of oral hygiene care. Helen Worthington, one of the authors on the review and Co-ordinating Editor of the Cochrane Oral Health Group at the University of Manchester in the UK tells us more.. Helen: Many patients in intensive care units in hospital need mechanical ventilation because their ability to breathe unassisted is impaired by trauma, a medical condition or recent surgery. One of the complications that may develop is ventilator-associated pneumonia, which is generally defined as a pneumonia developing in a patient who has received mechanical ventilation for at least 48 hours. The incidence of ventilator associated pneumonia in these patients has been found to be as high as 52% in some studies ...

UTRECHT, The Netherlands - Oral swabbing with antiseptics may be an inexpensive and effective way to prevent bacterial pneumonia in patients on mechanical ventilators, according to a study here.

The process of getting a person off a ventilator is called weaning. Usually we will want to remove sedatives at this time to have you fully awake.We do this so we have your full cooperation and so we can assess your readiness for weaning. Usually we go through a series of tests, such as breathing tests. We will also want to make sure you do well in spontaneous mode. This will usually involve removing any support provided by the ventilator, other than the minimal support needed to make up for breathing through ventilator tubing ...

Among the nations seven most populous states, Texas ranks last in the number of long-term nursing facilities for adult patients who cant breathe on their own, and near the bottom in how much it will pay for their care. If (ventilators) were a real good business to be in, thered be a lot more people doing it, said Dr. Keith Rapp, whose group practice consists of medical directors of nursing homes in Houston. State Sen. Mike Moncrief, D-Fort Worth, said he will direct the Senate Health and Human Services Committee staff to do a careful and detailed evaluation of the situation to determine why homes do not want to take ventilator patients. Smaller nursing home companies with fewer assets attract fewer lawsuits, industry experts say. Patients mangled in car accidents, paralyzed by gunshot wounds or weakened by diseases such as post-polio syndrome may live for decades, alert and able to communicate, thanks to a ventilator. A look at reimbursement rates in other states, and the corresponding

Ventilator-associated pneumonia (VAP), a bacterial infection that develops after 48 hours or more of intubation, is associated with high morbidity and mortality. Rapid identification of VAP is required to improve survival and to reduce avoidable treatment-associated side effects. Procalcitonin (ProCT), a blood test, is a reasonably specific marker of bacterial infection and its level increases early in sepsis. In this study, a ProCT serum level will be measured in 50 patients with clinically suspected VAP. We aim to show that the ProCT level will be high early in VAP and will stay high in patients with poor prognosis. This will help to address the potential role of ProCT as part of early diagnosis and management of VAP ...

Hospital-acquired and ventilator-associated pneumonia (HAP/VAP) are often selected for randomized clinical trials (RCTs) aiming at new drug approval. Guidelines for the design of such RCTs have been repeatedly updated by regulatory agencies. We hypothesized that large variability in the enrolled populations, the endpoints assessed and the HAP/VAP definition criteria may impact the results of these studies, and addressed this through a systematic review of HAP/VAP RCTs. A search (Pubmed-Embase-ICAAC-ECCMID) of all RCTs published between 1994 and 2016 comparing antimicrobial treatment for HAP/VAP in the intensive care unit was conducted. The populations enrolled, inclusion/exclusion criteria, statistical design and endpoints assessed were recorded. All unpublished RCTs recorded on the ClinicalTrials.gov registry were also screened. From the 93 abstracts reviewed, 39 potentially relevant studies were inspected, leading to 27 studies being included. As expected, illness severity or the proportion with VAP

Background. Comparative cohort studies are often conducted to identify novel therapeutic strategies or prognostic factors for ventilator-associated pneumonia (VAP). We aimed to evaluate the power of such studies to provide clinically and statistically significant conclusions with regard to mortality differences.. Methods. We searched in PubMed and Scopus for comparative cohort studies that evaluated mortality in patients with VAP. We calculated the central estimates and corresponding 95% confidence intervals (CIs) for mortality differences between compared patient groups. We also calculated the statistical power of the included studies to detect a difference in mortality that corresponds to a risk ratio of 0.80.. Results. We identified 39 (20 prospective) comparative cohort studies on VAP as eligible for inclusion in this analysis. The median absolute risk difference in mortality between compared groups was 10% (interquartile range [IQR], 5%-18%), and the median width of the 95% CI of the ...

Data to date is far from sufficient to describe the recent epidemiology of ventilator-associated pneumonia (VAP) in mainland China. This study aimed to estimate the overall incidence of VAP, with a special focus on its temporal trend and associated factors. Meta-analyses of 195 studies published from 2010 to 2015 were conducted, followed by subgroup analyses by methodological quality, pre-defined setting characteristics and attributes of populations. The overall cumulative VAP incidence in mainland China was 23.8% (95% confidence interval (CI) 20.6-27.2%), with the results showing high heterogeneity. The pooled incidence densities were 24.14 (95% CI 21.19-27.51) episodes and 22.83 (95% CI 19.88-26.23) patients per 1000 ventilator-days. A decline in the cumulative incidence was observed from 2006 (49.5%, 95% CI 40.0-59.0%) to 2014 (19.6%, 95% CI 10.4-31.0%); differences in the incidence rates were also documented according to Chinese provinces and diagnostic criteria (p | 0.001). Older age (≥60 years),

Background: Over the past few weeks there has been a shift in the management of critically ill COVID-19 patients. Many seem to have moved away from an intubate early strategy to the use of high flow nasal cannula (HFNC) and noninvasive ventilation (NIV). HFNC and NIV may obviate the need for endotracheal intubation in patients with acute respiratory failure. Mechanical ventilation is not a benign intervention as it has a number of associated complications including ventilator associated pneumonia, excessive sedation, delirium, ICU acquired weakness, as well as ventilator induced lung injury (VILI). NIV can cause lung injury from excessive negative pressure forces. However, mechanical ventilation can cause VILI from excessive positive pressure forces. There is a fine balance of when to use which modality, and when to transition from one modality to another that requires frequent bedside monitoring. NIV has been used successfully for COPD exacerbations and cardiogenic pulmonary edema, but its use ...

Although we also performed a multivariate analysis in the CPAP group, we did not find statistically significant differences due to the small size of this subset of patients.. Discussion. Our analysis identified 2 important predictors of NIV failure. The first and most strongly correlated was age, which is consistent with previous studies.4,11 More specifically, we found that age less than 6 months predicted NIV failure. This could be explained by the anatomical and physiological characteristics of this age group, which would result in a higher incidence of severe respiratory failure. Furthermore, these children have apnoeic episodes more frequently,17 and those born preterm in particular are more likely to experience patient-ventilator asynchrony18 compared to patients aged more than 7 months.19 On the other hand, the technical limitations of the ventilators and interfaces used in this age group complicate the use of NIV.. Another important predictor identified in the total sample was initial ...

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. This cliche´ is oxymoronic, analogous to saying that a woman can be minimally pregnant. The increase in cardiorespiratory load engendered by a switch from pressure support of 5 cm H2O or CPAP 5cm H2O to zero assistance at the point of extubation is enough to precipitate a lethal cataclysm in some patients. Because it is difficult to foretell which patients will be unable to cope with an increased cardiorespiratory load after extubation, I check that patients are able to breathe without respiratory distress for about thirty minutes on a T-piece without CPAP before removing an endotracheal tube . (Although less than ideal, an equivalent assessment can be performed through the use of Flow-by-provided that pressure support and CPAP are both set at zero ...
