Design outcomes

Primary

MeasureTime frame
SNHAP, defined as the interval between the induction of anesthesia and the occurrence of oxygen saturation (SpO2) upto 92%. Timepoint: Outcome will be assessed within 10 minutes of intervention.—

Secondary

MeasureTime frame
1) the time to obtain a FetO2 of 0.90. 2) the proportion of patients that reached 0.90 of FetO2. 3) the maximal FetO2 during preoxygenation. 4) the time needed to return to a SpO2 of 97% after ventilation resumption. 5)the mean arterial pressure during the experimental period. Timepoint: The outcomes will be assessed within 10 minutes of intervention.—
