Peri - operative ultrasonography was used to evaluate the effects of protective lung ventilation on the postoperative lungs of obese patients.The purpose of this study was to apply ultrasound lung ventilation area score to the monitoring of pulmonary complications in patients with postoperative obesity.To verify the reliability and practicability of perioperative lung ultrasound quantitative scoring.


Ultrasound lung ventilation area score was applied to monitor the pulmonary complications of patients after obesity operation to verify the perioperative period.

The reliability and practicability of quantitative lung ultrasound score to clarify the effect of protective lung ventilation under perioperative pulmonary ultrasound monitoring on obesity patients.To guide the management of mechanical ventilation under general anesthesia and the prevention and treatment of postoperative pulmonary complications
