Different Preoxygenation Methods In Cesarean Section

Assessment of Different Preoxygenation Methods With Oxygen Reserve Index In Cesarean Section

The study aimed to evaluate different preoxygenation methods (tidal volume for 3 minutes and 4 deep breaths) in pregnant women with oxygen reserve index (ORI).

After the routine monitoring of healthy ASA II pregnant patients between the ages of 18-45, different preoxygenation methods will be applied, and the oxygen status of the patients will be compared with ORI monitoring.
