Summary

Before going off to sleep patients are given oxygen to saturate blood with oxygen to extend time before a decrease in the level of oxygen in the blood occurs. During this period, obese patients have a faster decrease in the level of oxygen in their blood. This study uses a device called "high-flow nasal cannula" (HFNC), which delivers humidified high-flow oxygen through 2 small plastic tubes placed just inside nostrils. In the intensive care unit settings this device has been used extensively and has become a standard practice. Purpose of this study is to determine whether these high-flow nasal cannula increase the time safely when going to sleep during elective surgery.
