Sponsor's own description
After obtaining the approval of the hospital ethics committee, this prospective, observational study included written informed consent from 51 participants with 19\<BMI\<25 m/kg2 and 51 participants with BMI\>40 m/kg2 undergoing an elective surgical requiring endotracheal intubation. In addition to standard monitors, an oxygen reserve index (ORI) sensor was placed and baseline values were recorded. The participants were preoxygenated until end expiratory oxygen concentration (EtO2) is reached 90%. After anesthesia induction and endotracheal intubation, the breathing circuit was not connected endotracheal tube until the peripheral oxygen saturation (SpO2) decreased until 95%.ORİ and SpO2 values were continuously recorded. Time of tolerable apnea, ORI warning, SpO2 warning and added warning were also recorded.
