简要总结
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.
详细描述
Criteria for inclusion in the study:
Planned elective bariatric surgery under general anesthesia ASA 1-2 class Between 20-50 years 50 patients
- Group: Patients undergoing CPAP (Continuous Positive Airway Pressure) during preoxygenation will be included.
- 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.

研究组 & 干预措施
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.
干预措施: CPAP preoxygenation (Other)
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.
