|Actual Study Completion Date :||March 2011|
Active Comparator: A - 25° head-up position
Participants will be positioned at 25° angle for procedure.
Other: 25° head-up position
Participant will be positioned at 25° angle for procedure.
Active Comparator: B - 55° head-up position
Participants will be positioned at 55° angle for procedure.
Other: 55° head-up position
Participant will be positioned at 55° angle for procedure.
- Tolerable Apnea Time (TAT) [ Time Frame: 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.
- 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 [ Time Frame: Time until SpO2 decreased to 92%, up to 8 minutes ]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.
