Atelectasis evaluation with lung ultrasound is performe and score in 6 different areas before and after High flow nasal cannula oxygen. Pulmonary function tests and blood gas parameters are compared.During the procedure, the patient's blood pressure, heart rate, oxygen saturation, any complications that may develop will be recorded.Induction of anesthesia; difficult airway management, difficult mask and / or difficult intubation incidence, Mallampati scores, the use of one of the difficult intubation techniques during intubation, perioperative mechanical ventilation parameters (ventilation mode, tidal volume, respiratory frequency, end of tidal CO2 (carbon dioxide) pressure, PEEP usage, SpO2 (saturation oxygen), airway peak pressure, urine volume, arterial blood gas parameters are recorded.

Apply preoxygenation with facemask. Prior to induction of general anesthesia, preoxygenation will be applied with an oxygen supplement of 5 l / min to an endtidal O2\> 90%.Atelectasis evaluation with lung ultrasound is performe and score in 6 different areas before and after preoxygenation.
