- Primary Outcome Measures
Name Time Method Absolute differences between arterial partial pressure of carbon dioxide (PaCO2) and EtCO2. Delta EtCO2 of ventilator side= absolute differences between PaCO2 and EtCO2 measured on the ventilator side of the HME filter. Delta EtCO2 of patient side= absolute differences between PaCO2 and EtCO2 measured on the patient side of the HME filter.
