Comparison of four methods for assessing airway sealing pressure with the laryngeal mask airway in adult patients. (1/122)

We have compared four tests for assessing airway sealing pressure with the laryngeal mask airway (LMA) to test the hypothesis that airway sealing pressure and inter-observer reliability differ between tests. We studied 80 paralysed, anaesthetized adult patients. Four different airway sealing pressure tests were performed in random order on each patient by two observers blinded to each other's measurements: test 1 involved detection of an audible noise; test 2 was detection of end-tidal carbon dioxide in the oral cavity; test 3 was observation of the aneroid manometer dial as the pressure increased to note the airway pressure at which the dial reached stability; and test 4 was detection of an audible noise by neck auscultation. Mean airway sealing pressure ranged from 19.5 to 21.3 cm H2O and intra-class correlation coefficient was 0.95-0.99. Inter-observer reliability of all tests was classed as excellent. The manometric stability test had a higher mean airway sealing pressure (P < 0.0001) and better inter-observer reliability (P < 0.0001) compared with the three other tests. We conclude that for clinical purposes all four tests are excellent, but that the manometric stability test may be more appropriate for researchers comparing airway sealing pressures.  (+info)

Volumetric capnography in patients with acute lung injury: effects of positive end-expiratory pressure. (2/122)

The aim of the study was to analyse the effects of positive end-expiratory pressure (PEEP) on volumetric capnography and respiratory system mechanics in mechanically ventilated patients. Eight normal subjects (control group), nine patients with moderate acute lung injury (ALI group) and eight patients with acute respiratory distress syndrome (ARDS group) were studied. Respiratory system mechanics, alveolar ejection volume as a fraction of tidal volume (VAE/VT), phase III slopes of expired CO2 beyond VAE and Bohr's dead space (VD/VT(Bohr)) at different levels of PEEP were measured. No differences in respiratory system resistances were found between the ALI and ARDS groups. VD/VT(Bohr) and expired CO2 slope beyond VAE were higher in ALI patients (0.52+/-0.01 and 13.9+/-0.7 mmHg x L(-1), respectively) compared with control patients (0.46+/-0.01 and 7.7+/-0.4 mmHg x L(-1), p<0.01, respectively) and in ARDS patients (0.61+/-0.02 and 24.9+/-1.6 mmHg x L(-1), p<0.01, respectively) compared with ALI patients. VAE/VT differed similarly (0.6+/-0.01 in control group, 0.43+/-0.01 in ALI group and 0.31+/-0.01 in ARDS group, p<0.01). PEEP had no effect on VAE/VT, expired CO2 slope beyond VAE and VD/VT(Bohr) in any group. A significant correlation (p<0.01) was found between VAE/VT and expired CO2 slope beyond VAE and lung injury score at zero PEEP. Indices of volumetric capnography are affected by the severity of the lung injury, but are unmodified by the application of positive end-expiratory pressure.  (+info)

Oxygenator exhaust capnography as an index of arterial carbon dioxide tension during cardiopulmonary bypass using a membrane oxygenator. (3/122)

We have studied the relationship between the partial pressure of carbon dioxide in oxygenator exhaust gas (PECO2) and arterial carbon dioxide tension (PaCO2) during hypothermic cardiopulmonary bypass with non-pulsatile flow and a membrane oxygenator. A total of 172 paired measurements were made in 32 patients, 5 min after starting cardiopulmonary bypass and then at 15-min intervals. Additional measurements were made at 34 degrees C during rewarming. The degree of agreement between paired measurements (PaCO2 and PECO2) at each time was calculated. Mean difference (d) was 0.9 kPa (SD 0.99 kPa). Results were analysed further during stable hypothermia (n = 30, d = 1.88, SD = 0.69), rewarming at 34 degrees C (n = 22, d = 0, SD = 0.84), rewarming at normothermia (n = 48, d = 0.15, SD = 0.69) and with (n = 78, d = 0.62, SD = 0.99) or without (n = 91, d = 1.07, SD = 0.9) carbon dioxide being added to the oxygenator gas. The difference between the two measurements varied in relation to nasopharyngeal temperature if PaCO2 was not corrected for temperature (r2 = 0.343, P = < 0.001). However, if PaCO2 was corrected for temperature, the difference between PaCO2 and PECO2 was not related to temperature, and there was no relationship with either pump blood flow or oxygenator gas flow. We found that measurement of carbon dioxide partial pressure in exhaust gases from a membrane oxygenator during cardiopulmonary bypass was not a useful method for estimating PaCO2.  (+info)

In vitro and in vivo assessment of the Ventrak 1550/Capnogard 1265 for single breath carbon dioxide analysis in neonates. (4/122)

The Ventrak 1550/Capnogard 1265 (V&C) enables deadspace (VD) measurements to be made in neonates. The aim of our studies was to validate the V&C device for VD measurement in vitro (lung model) and in vivo (adult rabbits). Methods of measurement of VD using the V&C (automatic computation, interactive carbon dioxide-volume plot analysis, Bohr equation) were tested by comparing known added deadspace volumes (VDadd) with calculated VDadd. After producing a change in alveolar (VDalv) and physiological (VDphys) deadspace by in vivo broncho-alveolar lavage, VDalv and VDphys computed automatically were compared with values calculated by the Bohr-Enghoff equations. VDadd was slightly underestimated (absolute error in mean: automatically -0.61 ml; interactively -0.55 ml; Bohr -0.54 ml). The higher the VDadd, the lower the absolute errors and coefficients of variation (cv). The highest cv occurred for automatic analysis (approximately 11%) compared with < 6% for interactive analysis or the Bohr equation. Average differences between results calculated automatically and by the Bohr-Enghoff equation were -0.79 ml for VDalv (95% confidence interval -2.02 to 0.44 ml) and -0.23 ml for VDphys (-0.6 to 0.14 ml). We conclude that the V&C can be used in newborn infants undergoing mechanical ventilation, if changes in VD are < 5 ml, interactive analysis or the Bohr equation should be used.  (+info)

Measurement of carbon dioxide production in very low birth weight babies. (5/122)

BACKGROUND: CO2 production is most commonly measured by using indirect calorimetry to quantify elimination of CO(2) in breath (VCO2). An alternative is to measure the rate at which CO2 appears in the body pool (RaCO2) by infusing a (13)C labelled bicarbonate tracer. VCO2 and RaCO2 generally differ but are related by c, a factor that adjusts for the incomplete recovery of infused tracer in the breath. The literature relating to human studies cites a wide range of values for c but the only neonatal study to determine c empirically estimated a mean value of 0.77. AIM: To estimate fractional recovery rate, c, in very low birthweight babies, and assess the feasibility of using the isotopic technique to measure CO2 production during mechanical ventilation. METHOD: Eleven spontaneously breathing, continuously fed, very low birthweight infants (median birth weight 1060 g, median gestational age 29 weeks) were studied. RESULTS: Mean (SD) VCO2 was 9.0 (2.0) ml/min (standard temperature and pressure dry, STPD) and mean (SD) RaCO2 was 9.6 (2.1) ml/min (STPD). The mean (SD) value of c was estimated as 0.95 (0.13). The 95% confidence intervals of the mean were 0.87-1.03. CONCLUSIONS: The results emphasise the importance of measuring c for a given study population rather than assuming a value based on adult studies. The close approximation of RaCO2 and VCO2 in this group of babies implies that the labelled bicarbonate infusion technique could be used to measure simply CO2 production during mechanical ventilation.  (+info)

Breath interval as a measure of dynamic opioid effect. (6/122)

We measured breath interval to characterize the time course of opioid effect in anaesthetized patients breathing spontaneously during knee replacement surgery with concurrent regional nerve blockade. Breath interval was recorded before and after a single dose of fentanyl 0.75 microgram kg-1 i.v. Breath interval was measured between the start of successive inspirations, identified by a decrease in carbon dioxide concentration, sampled at the laryngeal mask connection. Nineteen patients were admitted to the study, of whom nine were withdrawn (there was a recording failure for one patient, five patients had inadequate block and three were excessively depressed by the fentanyl). Using MKMODEL software, the mean (SD) dynamic elimination half-life and dynamic mean brain residence time of fentanyl were 15.3 (7.8) and 24.1 (8.1) min, respectively. The times to detection of change from baseline, and peak effect of fentanyl on breath interval were 0.9 (0.6) and 5.2 (1.4) min, respectively. Breath interval increased from 2.9 (1.0) s to a maximum of 9.0 (5.7) s. There were no differences between the time course of changes in breath interval and end-tidal carbon dioxide concentrations. End-tidal carbon dioxide concentrations increased from a baseline of 6.6 (0.9)% to a peak of 8.2 (0.8)%. Breath interval was a useful and reproducible method of monitoring the duration of opioid effect in anaesthetized patients breathing spontaneously when surgical stimulation was not affecting the CNS. The data provide information on the duration of action of fentanyl and could guide dosage.  (+info)

Arterial to end-tidal carbon dioxide pressure difference during laparoscopic surgery in pregnancy. (7/122)

BACKGROUND: There is controversy about whether capnography is adequate to monitor pulmonary ventilation to reduce the risk of significant respiratory acidosis in pregnant patients undergoing laparoscopic surgery. In this prospective study, changes in arterial to end-tidal carbon dioxide pressure difference (PaCO2--PetCO2), induced by carbon dioxide pneumoperitoneum, were determined in pregnant patients undergoing laparoscopic cholecystectomy. METHODS: Eight pregnant women underwent general anesthesia at 17-30 weeks of gestation. Carbon dioxide pnueumoperitoneum was initiated after obtaining arterial blood for gas analysis. Pulmonary ventilation was adjusted to maintain PetCO2 around 32 mmHg during the procedure. Arterial blood gas analysis was performed during insufflation, after the termination of insufflation, after extubation, and in the postoperative period. RESULTS: The mean +/- SD for PaCO2--PetCO2 was 2.4 +/- 1.5 before carbon dioxide pneumoperitoneum, 2.6 +/- 1.2 during, and 1.9 +/- 1.4 mmHg after termination of pneumoperitoneum. PaCO2 and pH during pneumoperitoneum were 35 +/- 1.7 mmHg and 7.41 +/- 0.02, respectively. There were no significant differences in either mean PaCO2--PetCO2 or PaCO2 and pH during various phases of laparoscopy. CONCLUSIONS: Capnography is adequate to guide ventilation during laparoscopic surgery in pregnant patients. Respiratory acidosis did not occur when PetCO2 was maintained at 32 mmHg during carbon dioxide pneumoperitoneum.  (+info)

Non-invasive respiratory monitoring in paediatric intensive care unit. (8/122)

Monitoring respiratory function is important in a Paediatrics Intensive Care Unit (PICU), as majority of patients have cardio-respiratory problems. Non-invasive monitoring is convenient, accurate, and has minimal complications. Along with clinical monitoring, oxygen saturation using pulse oximetry, transcutaneous oxygenation (PtcO2) and transcutaneous PCO2 (PtcCO2) using transcutaneous monitors and end-tidal CO2 using capnography are important and routine measurements done in most PICUs. Considering the financial and maintenance constraints pulse oximetry with end tidal CO2 monitoring can be considered as most feasible.  (+info)

Use of capnography to monitor CPR quality and detect ROSC should be done initially by attaching an EtCO2 monitoring device to the bag-valve-mask device. Once an advanced airway is placed, capnography serves the added purpose of assuring that the airway remains in place.. Resuscitation involves maximal patient movement and offers considerable opportunity for airway displacement. In fact, the degree of patient movement seen in any patient transport, both in and outside the hospital, is significant enough to cause unrecognized airway displacement. Continuous waveform capnography is a standard of care in any patient transport environment.[8]. The utility of capnography in detecting ROSC serves an added purpose of monitoring perfusion and metabolism post-arrest. Once ROSC is achieved, capnography provides the earliest indicator of deterioration in perfusion. A falling EtCO2 signals the resuscitation team that the patient is re-arresting.. TBI and EtCO2. Capnography serves an additional role of ...
I grabbed two capnography cannulas from the storeroom today and tossed them in the bag without looking at them. We were called for a diabetic and found an 79 year old female quite anxious stating that her blood sugar was over 400 and she felt very dizzy and had a headache. I tossed her on the capnography and got a reading around 35 with a good wave form everything quite normal. I asked my partner to attach the oxygen tubing to hook it up to the cannula port on the capnography cannula, but then we realized this batch of cannulas lacked an 02 extension, so we had to put an 02 cannula on the woman in addition to the capnography cannula. I noticed her ETCO2 started to go down and I at first thought it was because she was hyperventilating. It went all the way down to 17. And then I thought maybe the oxygen cannula has something to do with it. The moment I took the oxygen cannula off, her ETCO2 went right back up to 35. The oxygen cannula was obviously diluting the carbon dioxide sample. Heres the ...

In emergency settings, verification of endotracheal tube (ETT) location is important for critically ill patients. Ignorance of oesophageal intubation can be disastrous. Many methods are used for verification of the endotracheal tube location; none are ideal. Quantitative waveform capnography is considered the standard of care for this purpose but is not always available and is expensive. Therefore, this feasibility study is conducted to compare a cheaper alternative, bedside upper airway ultrasonography to waveform capnography, for verification of endotracheal tube location after intubation. This was a prospective, single-centre, observational study, conducted at the HRPB, Ipoh. It included patients who were intubated in the emergency department from 28 March 2012 to 17 August 2012. A waiver of consent had been obtained from the Medical Research Ethics Committee. Bedside upper airway ultrasonography was performed after intubation and compared to waveform capnography.

Background: Misplacement of airway devices inserted by Emergency Medical Services (EMS) personnel during out-of-hospital cardiac arrest (OHCA) remains a life-threatening problem. Although the manual use of colorimetric end-tidal carbon dioxide (etCO2) detectors or real time capnography has reduced the incidence of misplaced airways, the validation process is cumbersome.. Objective: To validate the performance of a defibrillator-based capnogram (CO2) analysis program to provide an automated airway placement check that can be initiated immediately after airway placement and following any patient transfer.. Methods: Recordings from 210 OHCA patients with capnogram waveforms were collected from 2008 to 2010 in two EMS agencies based in Oregon&Texas. The capnogram files were extracted from storage cards of Philips HeartStart MRx defibrillators. Five-hundred (n=500) representative 20-second segments were selected and annotated as either success (n=344) or failure (n=156) by two emergency physicians ...

An end tidal carbon dioxide addition device coupling to a nasal cannula used on patients under general anesthesia or sedated, to continuously measure the carbon dioxide content of the expired breath. A first embodiment device has a body a pair of nasal ducts with clips to attach to a nasal cannula. A pair of oral ducts collects exhaled oral gases which are combined with the nasal gasses to be analyzed for tidal carbon dioxide content. A pair of posts adjacent the oral ducts stabilize the device on a sedated patient. A second embodiment integrates a nasal cannula with the body to provide an economical disposable device and substitutes a flattened region with an array of apertures for the oral ducts.
I did a presumption involving a fresh death and questionable DNR detailed in the story Understand. I had never used capnography before on a presumption, but ever the field scientist, tried it(putting a capnography cannula on the patient): 1) to document the apnea, 2)to give myself some time to think of what I was going to say about the unusual circumstances surrounding the case when I called in for permission to not begin CPR, and 3) out of pure curiousity. I immediately saw the flat line of apnea, but then a few minutes later was startled by the appearence of the number 7 in the capnometer without a wave form. I figured later that the 7 probably came from a stomach hiccup or some type of passive gas escape. Heres the trend summary ...
End-tidal capnography has gained momentum over the years as a standard for monitoring patients undergoing procedural sedation in the emergency department, with a level B recommendation coming out of ACEPs clinical policy regarding procedural sedation in 2014. It can identify hypoventilation earlier than other monitoring tools we have at our disposal in the emergency department, but its utility doesnt end there. It can quickly and efficiently answer clinical questions beyond that of sufficient ventilation. Are the chest compressions being performed on your cardiac arrest inadequate? Should you stop resuscitation efforts? Is your hyperglycemic diabetic in diabetic ketoacidosis (DKA)? Is that nasogastric tube in the stomach? End-tidal capnography can lend insight to these questions that emergency physicians encounter on a daily basis. End-tidal carbon dioxide (EtCO2) sensibly correlates with the pathophysiology of those and many other disease processes and can help guide decision making on your ...
In the American Heart Association (AHA) 2015 Guidelines, continuous waveform capnography is a Class I, LOE A recommendation for confirming and monitoring correct placement of an endotracheal tube.1. Because a sustained increase in PETCO2 during CPR is an indicator of return of spontaneous circulation (ROSC), the AHA Guidelines also recommend using capnography in intubated patients to monitor CPR quality, optimize chest compressions, and detect ROSC during chest compressions or when the rhythm check reveals an organized rhythm (Class IIb, LOE C).1 ...

Will You Do an Elective GA Case with No Capnograph Available? "Yes, Scheduled Anesthesia Services May Be Continued In Circumstances Where Capnography Becomes Unavailable Because of Equipment Failure" by Hugh C. Gilbert, M.D. Capnography has become an important aspect of intraoperative monitoring. Its value in assessing the appropriate placement of an endotracheal tube during the induction of general anesthesia has been strongly encouraged by the House of Delegates of the American Society of Anesthesiologists, and many departments of anesthesiology require continuous capnography as part of their rules of conduct for intraoperative care. Insurance carriers have embraced capnography as one of the important factors on which reductions in the cost of medical liability insurance coverage can be based. The issue before us is not the value of capnography as a monitor for ensuring the adequacy of ventilation in patients undergoing anesthesia care, but whether an entire list of scheduled procedures should ...

Capgnography is the monitoring of the concentration or partial pressure of carbon dioxide in the expired respiratory gases; as such, it is a non-invasive monitoring technique which allows fast and reliable insight into ventilation, circulation and metabolism. Capnography has proven to be more effective than clinical judgement alone in the early detection of adverse respiratory events. The shape of a capnogram is identical in all humans with healthy lungs; any deviations in shape must be investigated to determine a physiological or a pathological cause of the abnormality.. Data from a previous pilot study yielded two major findings:. ...

OBJECTIVE: To examine the feasibility of using expiratory capnography as an indicator of airway obstruction in non-intubated resuscitation room patients. METHODS: Patients with potential respiratory compromise admitted to the resuscitation room were assessed for widespread expiratory wheeze. This was taken as clinical evidence of airways obstruction. Expiratory capnograms of these patients and patients who had no wheeze were obtained. The traces were analysed for basic morphology and where appropriate the slope ratio (SR) between phase 1 (S1) and phase 2 (S2) of the trace was obtained ...
Capnography monitoring as a standard of care is growing, but it requires an investment in monitors and sampling lines. Portable monitors can range from $3,750-5,400 and sampling lines from $10-15.

VAISALA has a new versatile solution for the measurement of carbon dioxide (CO2) in demanding applications. The GMM220 series OEM CO2 module is the latest addition to the range of Vaisala CO2 transmitters.
BACKGROUND: In spontaneously breathing patients, the differences between arterial PaCO2 and end-tidal CO2 (EtCO2) and the influence of bronchial obstruction have not clearly established.. MATERIAL/METHODS: This was a prospective observational study. Patients (n=120) were classified according to spirometric criteria into groups with normal, mild, moderate, and severe obstruction. Arterial blood gases and capnography were performed in two ways: with a tidal volume (Vt) and a non-forced maximal expiration maneuver. Pearson correlation coefficients (r) between PaCO2 and capnographic values were determined for the entire cohort and the subgroups. A concordance study was performed with Bland-Altman analysis.. RESULTS: Comparison of PaCO2 and EtCO2 measured at Vt showed a significant correlation (r=0.722, p,0.01) for the entire cohort, but with a significant mean infra-estimation: P(a-et)CO2=5.2+/-4.4 mmHg, p,0.05. Analysis of subgroups: At Vt, P(a-et)CO2 was 1.7+/-2.9 mmHg (p=ns) in patients with ...
Literature Review: The capnograph represents continuous monitoring of the partial pressure of CO2 in a circuit and has four main phases [1]. The first phase (phase 1) represents the end of a breath; this is dead-space ventilation, meaning air that did not participate in gas exchange is cleared from the airways. Phase 2 is a rapid up-tick in the amount of CO2 measured which represents the first gas that is being sampled from the alveoli, i.e. initial exhalation. Phase 3 is known as the "alveolar plateau". It represents the amount of CO2 in all the alveoli, on average. This plateau should have a slightly positive inclination due to the continuous excretion of CO2 into the alveoli becoming progressively smaller and the late emptying alveoli with a low V/Q ratio containing a relatively higher concentration of CO2. The value displayed on the monitor is equal to the end-tidal CO2 measured at the end of Phase 3. This is when the CO2 concentration reaches a maximum at the end of exhalation and reflects ...
Normal respiration is driven by CO2 levels in the blood stimulating respiratory centers in the brain. Many of the drugs that we use in anesthesia suppress this phenomenon. Patients are often unable to compensate for anesthetic related hypoventilation for example. As patients emerge from anesthesia, the respiratory drive becomes even more important because if it remains suppressed the elimination of inhalant is delayed. Some degree of hypercapnia during anesthesia may be tolerated in a spontaneously breathing patient without underlying disease (up to of 60mmHg). Manually ventilating too often in order to achieve a "normal" capnograph reading can cause the patient to rely on the anesthetist for ventilation. Assisting ventilation too aggressively will drive the PaCO2 down to a point where the patient will stop spontaneous ventilation. We do this intentionally sometimes in order to capture respirations when putting a patient on a mechanical ventilator or to stop the motion of breathing during ...
Background: Bronchopulmonary dysplasia (BPD) is characterized by structural lung changes which may affect ventilation distribution. Volumetric capnography (VC) has been used in adults to provide information on ventilation homogeneity and ventilation-over-perfusion status. The aim of this study was to assess the value of VC in assessing ventilation homogeneity in infants with BPD.. Methods: Lung function (tidal breathing - multiple breath washout) parameters from 132 healthy infants (94 term, 38 preterm) and 66 infants with moderate or severe BPD were compared. Expiratory capnograms were obtained by mainstream capnography over 100 tidal breaths. The slopes of phases II (SII) and III (SIII) were calculated by linear regression on emprirically chosen intervals as follows: For SII between 5 and 60% of the end-expiratory CO2 fraction and for SIII between 40, 50, or 60 and 95% of the expiratory volume. The correlation between these indices and lung clearence index (LCI) was also assessed.. Results: ...

Capnography may be used as an adjunct to pulse oximetry and clinical assessment to detect hypoventilation and apnea earlier than pulse oximetry and/or clinical assessment alone. However, there is a lack of evidence that capnography reduces the incidence of serious adverse events (neurologic injury caused by hypoxia, aspiration, death) (ACEP Level B). [1] ...

EMERYVILLE, Calif.-With a half-million-dollar National Science Foundation (NSF) grant in hand, nanotechnology developer Nanomix Inc. is moving its disposable capnography sensor for anesthesia monitoring into clinical testing. Capnography is the measurement of carbon dioxide concentration in human respiration, and is a standard of care during administration of anesthesia.. The prototype device, fabricated at Nanomixs Emeryville cleanroom, uses carbon nanotubes as the active sensing element. The nanotubes, says Nanomix, are individual molecules to which electrical leads can be attached. Electrical properties of the molecules are monitored macroscopically as they respond to chemical changes at the molecular level. The company says its nanotube sensors are highly sensitive over a broad range of environments, and that multiple nanosensors can be integrated on one chip, with minimal power and space requirements.. "Physicians will be equipped to significantly improve monitoring of patients, especially ...
An adaptor (10) is used to convert an oxygen face mask (50) for capnography. The adaptor (10) comprises a body (12) with a first connector (14), a second connector (16) and a passageway (18) extending therebetween. The first connector (14) is configured to engage a respiratory gas (C02) monitoring line (not shown). The second connector (16) has a substantially tapering profile, with its cross-section decreasing with increasing distance from the first connector (14). The substantially tapering profile of the second connector (16) is made up of a plurality of annular ribs (24), separated by annular grooves (26), forming a graduated or stepped configuration. Such a configuration is helpful for securely engaging any one of a number of apertures of different sizes when converting the oxygen face mask (50) for capnography.

Breathing retraining (BR) improves symptoms, psychological well-being and quality of life in adults with asthma; but there remains uncertainty as to mechanism of effect. One of the intuitively logical theories is that BR works through altering breathing pattern. There is currently no evidence, however, that BR does result in measurable changes in breathing pattern. In this case report we describe the effects of physiotherapy BR on a 57-year-old female with a 10-year history of asthma. Data were collected before and after a physiotherapy BR program comprising three sessions over 18 weeks: breathing pattern (respiratory inductive plethysmography (RIP); physiology (end tidal carbon dioxide (ETCO2), heart rate, oxygen saturations, spirometric lung function); questionnaires (Asthma Control Questionnaire (ACQ), Hospital Anxiety and Depression Score, Nijmegen Questionnaire); and medication usage ...

We support availability of capnography for all paramedics.. These stories illustrate the benefits of broader use of gas analysers:. Pre-oxygenation by the Emergency Physician. After 5 minutes of pre-oxygenation the emergency physician was unable to intubate. She was surprised just how quickly the patient desaturated and felt the stress this caused clouded her judgement. The patient eventually obtained a surgical airway.. The emergency physician later noticed the bag valve mask used for pre-oxygenation wasnt connected to an oxygen source.. An anaesthetist who attended couldnt help thinking how end-tidal oxygen monitoring would have helped assess pre-oxygenation effectiveness.. The patients carotid artery was severed performing the surgical airway and he died 4 days later.. Night registrar on the ward. A junior registrar was called to review a patient whod desaturated on the ward. The combination of sedative medications with a morphine PCA had led to the patients deterioration.. The registrar ...
Introduction: Although metabolic problems after cardiac arrest (CA) have been postulated, the actual measurement of metabolic alterations after CA remain undescribed. The measurement of oxygen extraction (VCO2), carbon dioxide excretion (VCO2), and respiratory quotient (RQ), reflect the energy metabolism and may provide insight into the post-arrest metabolism.. Objective: To investigate metabolism alterations after CA, which may be detected via changes in VCO2, VO2, and RQ. Secondarily to test whether it is affected by therapeutic temperature management (TTM). Methods: Sixteen male rats underwent a protocol for 10 minutes of asphyxial CA and return of spontaneous circulation (ROSC). Three groups were compared: Group1: controls (no-CA, n=5), group2: CA (n=6), and group3: CA with TTM (n=5). Within the TTM group, the body was cooled to 33 °C. Capnography was recorded and O2 extraction was measured for 120min to measure VCO2 and VO2. RQ was the ratio of VCO2/VO2.. Results: The post arrest VCO2 was ...
I believe this problem is under appreciated in the use of the external (transcutaneous) pacer. Ineffective pacemaker discharges create an electrical artifact. As the deflection returns to baseline it resembles a QRS complex (false capture). To complicate things further, the skeletal muscle twitch caused by the pacers impulse may be mistaken for a pulse. Heres a post from EMS 12-Lead which illustrates a case of false capture and provides some troubleshooting tips. Heres another post (from the 12-Lead ECG blog) which adds another troubleshooting tip: using capnography! ...

A respiration pattern of a number of respiration cycles is detected and breath intervals (BI) and tidal volume (TVOL) measurements of each of the respiration cycles are respectively determined. An unevenly sampled instantaneous minute ventilation (iMV) signal is produced using the BI and TVOL measurements, and an evenly sampled iMV signal (resampled iMV signal) is produced using the unevenly sampled iMV signal. Disordered breathing is detected based on a comparison between a baseline threshold and the resampled iMV signal.
TY - JOUR. T1 - Alveolar dead space as a predictor of severity of pulmonary embolism. AU - Kline, Jeffrey A.. AU - Kubin, Anita K.. AU - Patel, Manish M.. AU - Easton, Edward J.. AU - Seupal, Rawle A.. PY - 2000/6. Y1 - 2000/6. N2 - Objective: To determine whether the alveolar dead space volume (V(D)alv), expressed as a percentage of the alveolar tidal volume (V(D)alv/V(T)alv), can predict the degree of vascular occlusion caused by pulmonary embolism (PE). Methods: Fifty-three subjects with suspected PE were prospectively studied. Pulmonary embolism was diagnosed in 33 by high- probability ventilation/perfusion (V/Q) scan (n = 19) or by pulmonary arteriography (PAG, n = 14). Pulmonary embolism was excluded by PAG in 20 subjects. The V(D)alv/V(T)alv was determined from volumetric capnography and arterial blood gas analysis, which permits measurement of the physiologic dead space, V(D)phys (mL) = [(PaCO2 - PeCO2)/PaCO2] · tidal volume. Airway dead space (V(D)aw) was subtracted to yield the ...
Her early clinical research focused on the use of bedside technology, including capnography, portable spirometry and bedside ultrasonography to improve the accuracy of patient care in the emergency department. She then began honing in on capnography, assessing its use to monitor ventilation in patients with acute asthma exacerbations, altered mental status, procedural sedation and endotracheal intubation, as well as assessing the utilization of capnography in different patient care areas. Melissas focus is now on translational research, and improving the dissemination and implementation of research into practice. She has explored the barriers and facilitators to the implementation of technology into acute care settings. Dr. Langhan has now incorporated this data into the development of a pilot study to improve use of these capnography in the emergency department for critically ill patients. Her overarching goal is to reduce adverse events and improve quality of care among this vulnerable ...
Physiological Dead Space ( Total Dead Space ) = Conducting airways (Anatomic Dead Space) + Pulmonary capillaries (Alveolar Dead Space).
This study introduces a new equal area method for the calculation, representation, and visualization of physiologic dead space based on a principle similar to the Fowler equal area method. The new method is analytically identical to the Bohr-Enghoff equation and yields numerical results that do not differ significantly from those calculated directly by the Bohr-Enghoff equation. Advantages of this new method include the following: (1) the graphical representation on a linear scale of the relations between all of the dead space volumes and fractions, including Vdanat, Vdalv, Vdphys, Vt, Vdanat/Vt, Vdalv/Vt, Vdphys/Vt, and Vdalv/Vtalv, which is especially helpful for the visualization of dead spaces during bedside monitoring of patients; (2) the use of a principle similar to that used in the Fowler equal area method, which makes the calculation of anatomical and physiologic dead spaces on the carbon dioxide expirogram consistent; (3) the use of a more straightforward method than the partitioning ...
The subjects wore a nasal mask (Respironics Inc, Murrayville, Pennsylvania, USA) connected to a heated pneumotachometer (Hans Rudolph Inc, Kansas City, Missouri, USA) and a differential pressure transducer (Validyne Corp, Northbridge, California, USA) calibrated with a rotameter for measurement of airflow. Inspiratory (Ti) and expiratory (Te) times were determined from this signal and it was electronically integrated for calculation of tidal volume (Vt). Minute ventilation (VE) was calculated as the sum of all Vt per minute. The duty cycle (Ti/Ttot) was also calculated for each breath. End-tidal carbon dioxide tension (Petco2) was measured from expired air within the nostril using a calibrated infrared CO2 analyser (Capnograph/Oximeter Monitor, BCI, Waukesha, Wisconsin, USA) while arterial oxygen saturation (Sao2) was measured using a pulse oximeter probe attached to the index finger (Capnograph/Oximeter Monitor).

We hypothesize that capnography could detect hypoventilation during induction of bronchoscopic sedation and starting bronchoscopy following hypoventilation, may decrease hypoxemia. Patients were randomized to: starting bronchoscopy when hypoventilation (hypopnea, two successive breaths of at least 50% reduction of the peak wave compared to baseline or apnea, no wave for 10 seconds) (Study group, n = 55), or when the Observer Assessment of Alertness and Sedation scale (OAAS) was less than 4 (Control group, n = 59). Propofol infusion was titrated to maintain stable vital signs and sedative levels. The hypoventilation during induction in the control group and the sedative outcome were recorded. The patient characteristics and procedures performed were similar. Hypoventilation was observed in 74.6% of the patients before achieving OAAS < 4 in the control group.

Results There were 106 patients with a diagnosis of obstructive or cardiac causes of dyspnoea that had prehospital ETCO2 levels measured during the study period. ETCO2 was significantly lower in patients diagnosed with CHF (31 mm Hg 95% CI 27 to 35) versus obstructive pulmonary disease (39 mm Hg 95% CI 35 to 42; p,0.001). Lower ETCO2 levels predicted CHF, with an area under the Receiver Operating Characteristics Curve of 0.70 (95% CI 0.60 to 0.81). Using ETCO2 ,40 mm Hg as a cut-off, the sensitivity for predicting heart failure was 93% (95% CI 88% to 98%), the specificity was 43% (95% CI 33% to 52%), the positive predictive value was 38% (95% CI 29% to 48%), and the negative predictive value was 94% (95% CI 89% to 99%).. ...

Several factors contribute to overall gas exchange in the lungs. Each breath (tidal volume) is composed of functional movement of air in and out of the alveolus and nonfunctional movement of air through bronchioles, bronchi, trachea, and nonperfused areas of lung (physiologic dead space). The physiologic dead space is approximately 30% of the tidal volume. The air remaining in the chest at the end of exhalation is referred to as the functional residual capacity. Dead space and the functional residual capacity do not contribute to gas exchange. The amount of air inhaled and exhaled in a minute is referred to as minute ventilation and is the product of the respiratory rate and tidal volume. Relatively small changes in the functional alveolar space demand large increases in the minute ventilation to maintain the same rate of gas exchange. Either raising the fraction of inspired oxygen (Fio2) or increasing the surface area or functional residual capacity of the lung can increase total alveolar ...
When more comprehensive forms of sedation are utilized like deep sedation or general anesthesia, you will be soundly sleeping through the entire procedure. You will enjoy an ultimate level of relaxation, without being disturbed by the sounds and sights of dental surgery. At the conclusion of your treatment, you will remember none of the procedure and you should expect to feel sleepy or somewhat groggy for a few hours.. With any type of sedation, a team of trained professionals will closely monitor your vital signs (heart rate, heart rhythm, oxygen saturation, blood pressure, end tidal carbon dioxide, and temperature) before, during, and after the procedure. Furthermore, you will be instructed to enlist the assistance of a responsible adult to see that you arrive home safely.. The details of the procedure for wisdom teeth extraction will be different for each patient. Your oral surgeon will discuss your main concerns and review your medical history to determine the method of sedation that is most ...

The measured values can be wirelessly transmitted or transmitted, via a cable, to a remote personal computer, a personal digital assistant (PDA), or other display devices such as digital watches or image projectors.
The management of patients suspected of having botulism consists of both supportive measures and antitoxin administration. Management is also complicated by the absence of a timely diagnostic biological marker to confirm the diagnosis and the time sensitive nature of treatment implementation to prevent further progression of illness.. In general, patients should be admitted to an appropriate area of the hospital for continuous monitoring of respiratory and neurological function. There is a risk of progressive muscle weakness and subsequent respiratory failure. Objective measures such as negative inspiratory force, pulse oximetry, and end-tidal capnography are often used to determine need for intubation and ventilator support.. Activated charcoal is generally administered to patients, if no contraindications exist. In vitro studies show that it absorbs serotype toxin A and it is suggested even after a substantial time delay as the bacteria and spores may still be present in the gastrointestinal ...
We coined the term relative [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] to indicate a quantitative value used to compare the relative oxygen delivery rates of the tested POCs. We do not have data to state how this relative [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] compares to actual [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] in a human. However, the steady-state oxygen reading inside the lung model should be quite close to the [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] for a given breath in a human, as the dilution of the oxygen pulse with room air in a single inspiration by a human should be the same as the steady-state dilution of oxygen delivered by the POC with the minute volume of air pumped by the lung simulator. The only difference would be that in a human the first portion of inspiration, from the anatomic dead space, would contain alveolar gas and thus have a slightly lower oxygen concentration than gas from the simulator that does not consume oxygen. ...

Lets run through a case example. Bear, is an aptly named healthy 6-year-old 33 kg chocolate Labrador retriever is premedicated with hydromorphone and dexmedetomidine, both IM. After Bear vomited and became sedate, a catheter is placed in his right cephalic vein and he is induced with midazolam and ketamine. He is intubated and placed on 2% isoflurane delivered in a circle system using 2 L/Min oxygen. He is clipped, prepped and received a morphine-saline epidural for his stifle surgery. He is moved and instrumented on the capnograph in the OR. There is no waveform, so his technician gives a breath, makes a nice "elephant holding the tail" waveform and the ETCO2 is 68 mm Hg. The seasoned staff reaches across and indicates that she should stop, because "he wont breath for himself if we keep breathing for him" so she stops. Because her employer is wonderful, and the patient is stable and large, she practices her art line skills on the tiny artery under the front paw and uses a point of care ...

The effects of carbon dioxide stimulation and resistance breathing are first considered, pooling measurements made in the control, relaxant, and recovery time periods, and values are given as medians and quartiles. Respiratory frequency, tidal volume, minute ventilation, and the pressure-time product were increased by carbon dioxide stimulation as expected. End-tidal carbon dioxide concentration increased from 5%(QV, 4.8-5.3%) to 6.5%(QV, 6.2-6.5%), and the change in end tidal carbon dioxide in individuals was 1.45%(QV, 1.2-1.6%). Minute ventilation increased from 6.9 l/min (QV, 6.5-7.7 l/min) to 16.6 l/min (QV, 14-18.7 l/min). These changes were accompanied by a reduction in airway resistance, from 1.2 (QV, 0.67-1.72) cm H2O [center dot] I sup -1 [center dot] s to 0.8 (QV, 0.46-1.33) cm H2O [center dot] I sup -1 [center dot] s. As expected, the pressure-time product increased, from 117 (QV, 83-138) cm H2O [center dot] s [center dot] min sup -1 to 275 (QV, 223-442) cm H2O [center dot] s [center ...
see Venous infarction. Venous air embolism (VAE) during an elective craniotomy for parasagittal meningioma resection. The surgery was done in the supine position with slightly elevated head position. VAE was provisionally diagnosed by sudden decreased in the end tidal carbon dioxide pressure from 34 to 18 mmHg, followed by marked hypotension and atrial fibrillation. Prompt central venous blood aspiration, aggressive resuscitation and inotropic support managed to stabilize the patient. Post operatively, he was admitted in neuro intensive care unit and made a good recovery without serious complications 15).. Intraoperative fatal pulmonary embolism 16).. Paraparesis can occur as a primary presentation of brain pathology at the motor strip along the parasagittal region.

Our study showed that using HFCWO for only 3 months produced a significant improvement in the feeling of breathlessness and increased cough at night. The increase in nocturnal cough may be an indication that HFCWO was effective for increasing secretion mobilization. Although there were no significant changes between the groups with respect to objective pulmonary function measures, peak expiratory flow increased in HFCWO users, whereas it decreased in nonusers (p = 0.179). The directional trend may be noteworthy.. The relentlessly progressive decline in respiratory muscle strength, as measured by FVC, oxygen saturation, and capnography continued despite treatment with HFCWO. However, we learned from this exploratory study which patients might benefit most from HFCWO use. First, our entry criteria were broad, allowing entry of patients with the most minimal symptoms of pulmonary dysfunction. These patients may have diluted therapeutic efficacy in our analysis of all participants. When only ...
Background. There may be significant difference between measurement of end-tidal carbon dioxide partial pressure (PetCO(2)) and arterial carbon dioxide partial pressure (PaCO2) during one-lung ventilation with low tidal volume for thoracic surgeries. Transcutaneous carbon dioxide partial pressure (PtcCO(2)) monitoring can be used continuously to evaluate PaCO2 in a noninvasive fashion. In this study, we compared the accuracy between PetCO(2) and PtcCO(2) in predicting PaCO2 during prolonged one-lung ventilation with low tidal volume for thoracic surgeries.. Methods. Eighteen adult patients who underwent thoracic surgeries with one-lung ventilation longer than two hours were included in this study. Their PetCO(2), PtcCO(2), and PaCO2 values were collected at five time points before and during one-lung ventilation. Agreement among measures was evaluated by Bland-Altman analysis.. Results. Ninety sample sets were obtained. The bias and precision when PtcCO(2) and PaCO2 were compared were 4.1 +/- ...
Chlamydia psittaci (Cp) is a respiratory pathogen capable of inducing acute pulmonary zoonotic disease (psittacosis) or persistent infection. To elucidate the pathogenesis of this infection, a translational large animal model was recently introduced by our group. This study aims at quantifying and differentiating pulmonary dysfunction and acid-base imbalances induced by Cp. Forty-two calves were grouped in (i) animals inoculated with Cp (n = 21) and (ii) controls sham-inoculated with uninfected cell culture (n = 21). For pulmonary function testing, impulse oscillometry, capnography, and FRC (functional residual capacity) measurement were applied to spontaneously breathing animals. Variables of acid-base status were assessed in venous blood using both (i) traditional Henderson-Hasselbalch and (ii) strong ion approach. Both obstructive and restrictive pulmonary disorders were induced in calves experimentally inoculated with Cp. Although disorders in respiratory mechanics lasted for 8-11 days, the pattern
Primary evaluation: In primary assessment of chest trauma patients the process of diagnosis and prompt treatment should be started simultaneously, searching and managing life-threatening lesions such as airway obstruction, tension pneumothorax, open pneumothorax, massive hemothorax, flail chest and cardiac tamponade. It is mandatory to monitor ECG, blood pressure, pulse oximetry and capnography. In this primary evaluation chest X-ray, ultrasound and blood gases are taken and decide whether to intubate the trachea, needle thorachostomy, chest tube thoracotomy in the emergency room, and/or pericardiocentesis. Secondary assessment: Once the life-threatening lesions are identified and treated a more extend and meticulous evaluation must be done. The first step is to make a complete and detailed review of the case. If there are relatives or friends we must obtain complete data of the patients medical history that can be relevant for the immediate comprehensive management: diabetes, hypertension, ...
