Cerebral and Peripheral Near Infrared Spectroscopy Monitoring in Low and High Flow Anaesthesia in Pediatric

"NIRS ,Ventilation parameters :~Until the patient is taken to the operating table and leaves the operating table routine monitoring parameters, BIS values ,cerebral and peripheral NIRS values, until the patient is intubated and extubated ventilation parameters These parameters; 0. min (before induction), 1. min after induction, pre-post intubation, 5. min, 10. min, 20. min, 30. min, 45. min, 60. min, 90. min after connecting to the ventilator. It will then be noted at 1 hour intervals, and finally at the 5th minute after extubation."

"Oxygen concentration :~Alarm limits appropriate to the patient's weight will be determined for all patients, the lower limit of inspired O2 will be set as 30%, the upper limit of inspired CO2 will be set as 5mmHg. If the inspired O2 value drops below 30%, the pulse oximeter peripheral SpO2 drops below 97, and the NIRS values drop by 20%, the oxygen concentration will be increased by 10%"
