Comparison of Apnea Tolerance in Two Positions of Patients With BMI 30-40

Comparison of Apnea Tolerance in Two Positions of Patients With Body Mass Index (BMI) 30-40

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.

Inclusion Criteria:

• American Society of Anesthesiologists (ASA) physical status I-III
• Body Mass Index (BMI) of 30-40
• Scheduled for an elective surgery that requires tracheal intubation

Exclusion Criteria:

• Patients with abnormalities of the upper airway that require awake tracheal intubation
• Asthma
• Chronic obstructive pulmonary disease
• Congestive heart failure
