Precise Control of End-tidal Carbon Dioxide Levels Using Sequential Rebreathing Circuits

End-tidal carbon dioxide monitoring.

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...

End-tidal Carbon Dioxide Measurements in Unintentional Non-Fire-Related Carbon Monoxide Poisoning

Background: Poisoning with carbon monoxide occurs occasionally worldwide, and the gold diagnostic standard is to measure carboxyhemoglobin level in the blood. This study investigated the correlation between carboxyhemoglobin and the end-tidal carbon dioxide levels in 50 patients with carbon monoxide poisoning. Methods: We recruited 50 volunteer patients who had been admitted to the Emergency S...

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...
