Summary

The purpose of this study is to investigate the clinical application value of inverse ratio ventilation in obese patients during induction of general anesthesia by studying the effect of inverse ratio ventilation on the safe apnea time.

Conditions

Interventions

OTHER

Inspiratory-to-expiratory (I : E) ratio of 1:2

After preoxygenation and induction of anesthesia, noninvasive positive pressure ventilation with inspiratory-to-expiratory (I : E) ratio of 1:2 for 5 min before endotracheal intubation.

OTHER

Inspiratory-to-expiratory (I : E) ratio of 2:1

After preoxygenation and induction of anesthesian, noninvasive positive pressure ventilation with inspiratory-to-expiratory (I : E) ratio of 2:1 for 5 min before endotracheal intubation.
