Correlation of End-Tidal Carbon Dioxide with Arterial Carbon Dioxide in Mechanically Ventilated Patients

BACKGROUND Patients undergone mechanical ventilation need rapid and reliable evaluation of their respiratory status. Monitoring of End-tidal carbon dioxide (ETCO2) as a surrogate, noninvasive measurement of arterial carbon dioxide (PaCO2) is one of the methods used for this purpose in intubated patients. OBJECTIVES The aim of the present trial was to study the relationship between end-tidal C...

Investigating the Relationship Between End Tidal Carbon Dioxide and Arterial Carbon Dioxide Pressure in Patients With Respiratory Distress Referred to the Emergency Room of Hazrat Rasool Akram Hospital

Background: Measuring End-Tidal Carbon Dioxide (ETCO-2) can be a non-invasive, fast, and reliable method to predict partial pressure of carbon dioxide (PaCO2) in patients with respiratory distress. This method, which can be a suitable substitute to measure PaCO2, is being used in many emergency rooms and operating rooms in developed countries, but its exact relationship with PaCO2 has not been ...

End-tidal carbon dioxide monitoring.

Monitoring carbon dioxide in mechanically ventilated patients during hyperbaric treatment.

BACKGROUND Measurement of the arterial carbon dioxide (P(a)CO(2)) is an established part of the monitoring of mechanically ventilated patients. Other ways to get information about carbon dioxide in the patient are measurement of end-tidal carbon dioxide (P(ET)CO(2)) and transcutaneous carbon dioxide (PTCCO2). Carbon dioxide in the blood and cerebral tissue has great influence on vasoactivity an...

The relationship between end tidal carbon dioxide and arterial carbon dioxide during controlled hypotensive anaesthesia.

OBJECTIVES To prospectively assess the magnitude of changes in the arterial-to-end tidal carbon dioxide gradient [P(a-ET)CO2] as well as in the ratio of physiological dead space to tidal volume (Vdphys/Vt) during controlled hypotensive anaesthesia, and to evaluate whether or not ventilatory requirements remain unaltered during this procedure. SUBJECTS AND METHODS Twelve adult patients with Am...

Disparity between mainstream and sidestream end-tidal carbon dioxide values and arterial carbon dioxide levels.

BACKGROUND Measuring and monitoring end-tidal carbon dioxide (PETCO2) is an important aspect of caring for critically ill patients. The 2 methods used for PETCO2 measurement are the mainstream and sidestream methods. OBJECTIVE To assess the agreement between PETCO2 measurements performed by mainstream and sidestream methods with the PaCO2 values. METHODS This was a prospective observational...
