Inclusion criteria

Inclusion criteria: Patients over 50 years old who scheduled to discharge the recovery room after general anesthesia at Samsung Medical Center

Exclusion criteria

Exclusion criteria: Patients who are scheduled to discharge to intensive care unit after surgery (high-risk surgery and patient group) Patients who need to apply unilateral lung ventilation Head and neck surgery (because of various postoperative respiratory management) Patients who cannot be performed postoperative lung ultrasonography (the site of operation)

Design outcomes

Primary

Measure	Time frame
lung ultrasonography (Each of the 12 quandrants was assigned a score of 0-3, total score 0~36);lung ultrasonography (Significant atelectasis was defined as a consolidation score = 2)	—

Secondary

Measure	Time frame
Peripheral Oxygen Saturation (SpO2) Levels Measured After recovery room;the frequency of Peripheral Oxygen Saturation (SpO2 <95%);the incidence of oxygen supply needed at time of discharge from recovery room;the incidence of oxygen supply needed at postoperative 1 day;Peripheral Oxygen Saturation (SpO2) in Room Air;postoperative pulmonary complication (diagnosed by Melbourne score);the duration of hospital stay;postoperative nausea/vomiting;chest X-ray;the frequncy of FiO2 change;Lowest Peripheral Oxygen Saturation (SpO2) Levels During Surgery;postoperative wound problem	—
