Abstract

We conducted a systematic review of the literature to better understand whether preoxygenation in non-critically ill patients (i.e. elective surgery patients) should be recommended, as it lengthens safe apnea time (the time required to reach oxygen saturation 18 years) and non-emergent patients between 2008 and 2017 were deemed eligible. A total of 11 papers were included. Our review suggests that preoxygenation is a safe and efficient technique that allows for longer safe apneic periods in obese (BMI > 30) non-critically ill patients. Non-obese (<30 BMI) patients do not seem to benefit as much from this procedure. However, there is insufficient evidence in the literature to provide a clear recommendation. For all patients, the procedure wa...
