Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CPAP
During preoxygenation, the ventilator device will be placed in spontaneous mode and set as CPAP: 5 cmH2O. The process will continue until the end-tidal O2 concentration ≥ 90% is removed.
CPAP preoxygenation
During preoxygenation, the ventilator device will be placed in spontaneous mode and set as CPAP: 5 cmH2O.
standard preoxygenation
During the preoxygenation, the ventilator device will be put in spontaneous mode and the procedure will continue until the End-tidal O2 concentration ≥90% is removed without additional pressure.
