Postoperative pulmonary complications (PPCs)
Conditions
Interventions
Postoperative day 1
2. Stimulation Parameters:Pulse width: 200 µs
Frequency: 30 Hz
Current intensity:Initial ramp-up from 10 mA to a noxious threshold (defined as participant-reported "tingling/pain" within 20 seconds)
Subsequent adjustment to sub-threshold current levels (20–60 mA)
Postoperative day 1
2. Apply sham stimulation for 30 minutes each session: abort stimulation if the participant reports "tingling/pain"
