简要总结
The purpose of this study is to compare the effect of the 25° head-up position versus the 55° head-up position on tolerable apneic time (TAT) in bariatric patients scheduled for laparoscopic adjustable gastric band surgery following maximum preoxygenation and rapid-sequence induction (RSI) of anesthesia.

结局指标
主要结局
Tolerable Apneic Time (TAT)
时间窗: Time between start of induction of general anesthesia (SpO2 100%) to decline of SpO2 94%, up to eight minutes
Measure of the TAT between groups to determine if the TAT is a function of the participant's position.
次要结局
- Peripheral arterial hemoglobin oxygen saturation (SpO2) trough(Time until SpO2 decreased to 92%, up to 8 minutes)
- Length of time to intubation (TTI)(Time between start of the tracheal intubation procedure to completion of tracheal intubation, up to 2 minutes)
