What STOP-BANG score is high risk for OSA?

STOP-BANG 5-8: high OSA risk (AHI >30 in 75% of patients). Score 3-4: intermediate risk. Score 0-2: low risk (NPV 90% for AHI >15). High-risk patients warrant overnight polysomnography before major surgery.

How does OSA risk affect perioperative management?

High STOP-BANG patients (5-8): increased risk of postoperative respiratory complications (OR 2.3 for desaturation, OR 1.8 for cardiac events). PACU monitoring extended, opioid-sparing analgesia preferred, CPAP continued perioperatively.

What AHI defines OSA severity?

AHI (apnea-hypopnea index per hour): mild 5-15, moderate 15-30, severe >30. Symptomatic OSA with AHI >5 or asymptomatic AHI >15 typically warrants CPAP. CPAP reduces cardiovascular risk, daytime sleepiness, and blood pressure.
