This study looks at how a special breathing technique, called an *alveolar recruitment maneuver*, can help lungs bounce back after laparoscopic gynaecologic surgery. This surgery is done with small cuts and uses gas to inflate the belly, which can make breathing harder. Pneumoperitoneum is when CO2 gas is used to create space in the belly for surgery. This can push on the lungs and make it tough to breathe. The study aims to see if using a breathing technique after the gas is let out can help the lungs work better again.

Key Points:

• The study involves patients aged 18 and above having surgery longer than 90 minutes.
• The breathing technique is used after pneumoperitoneum to help lungs recover.
• People with certain lung problems or high BMI might not be able to join.
