The purpose of this study is to compare the effect of the 25° head-up position versus the 55° head-up position on tolerable apnea time (TAT) after induction of general anesthesia in patients with a body mass index (BMI) of 30-40.

Tolerable Apnea Time (TAT)
Measure of the TAT between groups to determine if the TAT is a function of the participant's position.
Time frame: Time between start of induction of general anesthesia (SpO2 100%) to decline of SpO2 94%, up to eight minutes
Length of time to intubation (TTI)
Time frame: Time between start of the tracheal intubation procedure to completion of tracheal intubation, up to 2 minutes
Peripheral arterial hemoglobin oxygen saturation (SpO2) trough
Measure of the rebound SpO2. It is the lowest SpO2 reading reached subsequent to start of mechanical ventilation at the SpO2 value of 94% and it represents final completion of SpO2 decline.
Time frame: Time until SpO2 decreased to 92%, up to 8 minutes
