Actual (reported)The purpose of this study is to evaluate the relationship between the time needed to raise the oxygen concentration in patient's blood to 90% and his/or her body mass index. The prevalence of obesity in our society continues to rise. No studies have shown the time required for preoxygenation (oxygen given) in relation to body mass index (body weight in kg/height in meter2).

Actual (reported)Time to reach 90% end tidal oxygen saturation using monitor and stop watch
Using monitors on the anesthesia machine, we recorded the end tidal oxygen saturation value and also recorded the time at which the end tidal oxygen was recorded. From the information collected the relationship between BMI and gender with the time to 90% end tidal oxygen saturation will be evaluated.
1 to 10 minutes
Patients with BMI values between 18.5-24.9
Patients with BMI values between 25-29.9
Patients with BMI values between 30-49.9
The study population will consist of 100 subjects between the ages of 18-50 classified as ASA 1 or 2 with no limitations as to gender or race that are scheduled for elective surgery at Cedars-Sinai Medical Center. There are changes to lung functioning as functional residual capacity (FRC), closing capacity, and lung volume after age 50; therefore, the age limitation is set to age 50. Changes in lung and chest wall compliance necessitate the exclusion of anyone over the age of 50. Minors are also excluded as there is difficulty fitting the face mask due to a smaller physiology.
