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 ...
Capnography is increasingly being used by EMS personnel to aid in their assessment and treatment of patients in the prehospital environment. These uses include verifying and monitoring the position of an endotracheal tube or a blind insertion airway device. A properly positioned tube in the trachea guards the patients airway and enables the paramedic to breathe for the patient. A misplaced tube in the esophagus will lead to the patients death if it goes undetected. A study in the March 2005 Annals of Emergency Medicine, comparing field intubations that used continuous capnography to confirm intubations versus non-use showed zero unrecognized misplaced intubations in the monitoring group versus 23% misplaced tubes in the unmonitored group. The American Heart Association (AHA) affirmed the importance of using capnography to verify tube placement in their 2005 CPR and Emergency Cardiovascular Care Guidelines. The AHA also notes in their new guidelines that capnography, which indirectly measures ...

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. Specificity, sensitivity, positive

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 ...

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 ...

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.
