Correct answer: E — Continuous pulse oximetry for at least 24 hours postoperatively

Severe OSA (AHI >30): continuous pulse oximetry for ≥24 hours in a monitored bed (HDU/recovery). Risk of upper airway obstruction and central apnoea peaks in the first 24 hours, especially with opioid use. Minimise opioids, consider CPAP, position semi-upright.
