Types of End Tidal CO2 Monitors Sidestream monitors rely on a separate monitor connected to the patient's airway by a tube. Gas samples are aspirated from exhaled gas flow via the ventilator circuit and are read at the monitor. Sidestream monitors can be used with non-invasive ventilation.

When is end tidal CO2 monitoring used?
End-tidal capnography provides reliable ventilatory monitoring for non-intubated patients presenting after sedative overdose to the emergency department. Emerg Med Australas 2020; 32:164. Fearon DM, Steele DW. End-tidal carbon dioxide predicts the presence and severity of acidosis in children with diabetes.Dec 14, 2020
When should you monitor capnography?
When is EtCO2 monitoring indicated? EtCO2 should be monitored (in addition to pulse oximetry) whenever respiratory depression is a possibility (examples: pain management and sedation issues, history of sleep apnea). If ETC02 is >50 mmHg or greater: (In addition to the interventions above) 1.
What is the difference between end tidal CO2 and capnography?
This is end-tidal CO2 (ETCO2) which is normally 35-45 mm Hg. The capnograph is the waveform that shows how much CO2 is present at each phase of the respiratory cycle, and it normally has a rectangular shape. Capnography also measures and displays the respiratory rate.Apr 27, 2015
What is the difference between capnography and capnometry?
Capnography is the continuous analysis and recording of the CO2 concentration in respiratory gas. Although the terms capnography and capnometry are sometimes considered synonymous, capnometry means only the measurement of CO2 in respiratory gas (ie, analysis alone), without a continuous written record or waveform.Apr 1, 2011
What is capnography used for?
Capnography is an effective method to diagnose early respiratory depression and airway disorders, especially during sedation, leading to a reduction in serious complications (23, 24). Capnography provided more safety in monitoring patients during sedation.Jan 15, 2018
What is the difference between CO2 and PaCO2?
BE Base excess (positive number) or base deficit (negative number)
----- ---------------------------------------------------------------
PCO2 Partial pressure of carbon dioxide
PaCO2 Partial pressure of carbon dioxide in arterial blood
PvCO2 Partial pressure of carbon dioxide in venous blood
SO2 Oxygen saturation
What is the difference between capnography and end tidal CO2?
Waveform capnography represents the amount of carbon dioxide (CO2) in exhaled air, which assesses ventilation. ... The number is capnometry, which is the partial pressure of CO2 detected at the end of exhalation. This is end-tidal CO2 (ETCO2) which is normally 35-45 mm Hg.Apr 27, 2015
What is the difference between mainstream and sidestream capnography?
Mainstream capnography is characterized as invasive and non-diverting, meaning that the measurement of the ETCO2 is done at the airway, or the sample site, thus providing a real-time measurement of the carbon dioxide pressure. Sidestream, on the other hand, is non-invasive and diverting.Oct 3, 2018
When is capnometry used?
Capnometry, as a non‐invasive method, offers fast and reliable insight into certain pathophysiological processes and aids in the clinical evaluation of critically ill patients, especially those in cardiac arrest and requiring cardiopulmonary resuscitation, and assists in the monitoring patients after endotracheal ...
What 2 things can quantitative capnography be used for?
The 2020 AHA Guidelines for ACLS recommend using quantitative waveform capnography in intubated patients during CPR. Waveform capnography allows providers to monitor CPR quality, optimize chest compressions, and detect ROSC (return of spontaneous circulationreturn of spontaneous circulationReturn of spontaneous circulation (ROSC) is the resumption of a sustained heart rhythm that perfuses the body after cardiac arrest. It is commonly associated with significant respiratory effort.https://en.wikipedia.org › Return_of_spontaneous_circulationReturn of spontaneous circulation - Wikipedia) during chest compressions.
What is the primary difference between mainstream and sidestream capnography?
For example, a mainstream capnograph may provide a shorter response time because the EtCO2 doesn't have to travel as far to reach the sensor, but a sidestream capnography monitor may be more comfortable for the patient because the thin tubing that is connected is lighter and less bulky than a mainstream version.
