Comparison of end-tidal CO2 measured by transportable capnometer (EMMA™ capnograph) and arterial pCO2 in general anesthesia

An end-tidal CO2 monitor (capnometer) is used most often as a noninvasive substitute for PaCO2 in anesthesia, anesthetic recovery, and intensive care. Additionally, the wide spread on-site use of portable capnometers in emergency and trauma situations is now observed. This study was conducted to compare PaCO2 measurement between the EMMA™ portable-capnometer and sidestream capnometry. End-tidal CO2 (portable capnometer: EMMA™ capnograph, side...
