Design outcomes

Primary

Measure	Time frame
To compare the efficacy of volume-controlled vs pressure-controlled modes in obese patients undergoing laparoscopic cholecystectomies by comparing lung ultrasound scores(LUS scores) in both groupsTimepoint: Lung ultrasound scores T0 scan will be done before induction of anaesthesia T1 scan will be done 15 minutes after creation of pneumoperitoneum T2 T3 T4 T5 and T6 scans will be done at 15 minute intervals until the completion of surgery Tex scan will be done just before extubation Tpacu will be done after 1 hour of shifting in post anaesthesia recovery unit T24h scan will be done after 24 hours in the ward	—
