Design outcomes

Primary

MeasureTime frame
Arterial PCO2 in the recovery phase (last 90 min of the study) measured using arterial blood gas at specific time points in the recovery phase

Secondary

MeasureTime frame
The occurrence of a respiratory event as defined by: 1. Respiratory rate =5 breaths/min for = 3 min; 2. Oxygen saturation = 85% for = 3 min; 3. End-tidal PCO2 = 2 kPa or = 8 kPa for = 3 min; 4. Apnea for at least 30 s; 5. Any other respiratory event; all measured using a continuous flowsensor, gas analyzer, and custom made software to identify the respiratory rate 6. The comparison of arterial vs venous vs end-tidal PCO2 measured using the custom made software, gas analyzer and flowsensor in combination with the arterial blood gas with the blood gas analyzer
