The Comparison of the Methods Applied in Bariatric Surgery in Terms of Preoxygenation Time

The aim of the study was to evaluate the preoxygenation time by observing patients undergoing preoxygenation with CPAP (Continuous Positive Airway Pressure) and Mask Ventilation in the clinic.

Criteria for inclusion in the study: Planned elective bariatric surgery under general anesthesia ASA 1-2 class Between 20-50 years 50 patients 1. Group: Patients undergoing CPAP (Continuous Positive Airway Pressure) during preoxygenation will be included. 2. Group: Patients undergoing preoxygenation without CPAP will be included In both groups, the time from the anesthesia device to the endtidal O2 90% and the endtidal CO2 value in this order will be recorded. Heart rate, blood pressure, endtidal O2 and CO2 values will be recorded during preoxygenation and after intubation.
