STOP-BANG Obstructive Sleep Apnoea Screening

Screens for moderate-severe obstructive sleep apnoea using 8 clinical variables. Score ≥3 warrants further evaluation; ≥5 has high sensitivity for severe OSA.

S — Do you Snore loudly (louder than talking or loud enough to be heard through closed doors)?

T — Do you often feel Tired, fatigued, or sleepy during the daytime (e.g. fall asleep while driving)?

O — Has anyone Observed you stop breathing or choking/gasping during your sleep?

P — Do you have or are you being treated for high blood Pressure?

B — BMI > 35 kg/m²?

A — Age > 50 years?

N — Neck circumference > 40 cm (measured at thyroid cartilage)?

G — Gender = Male?

STOP-BANG Score/ 8

Low risk for moderate-severe OSA

Estimated OSA risk: ~3–7%. Routine clinical follow-up is appropriate. No specific anaesthetic precautions mandated, but screen again if symptoms change. Polysomnography (PSG) referral is not routinely required at this risk level.

RespP/F Ratio

Key indicator of oxygenation failure severity. Berlin definition: mild ARDS < 300, moderate < 200, severe < 100.

RespA-a Gradient

Differentiates causes of hypoxaemia. Elevated gradient suggests V/Q mismatch, shunt or diffusion defect.

RespBODE Index

Predicts all-cause and respiratory mortality in COPD. Superior to FEV1 alone as a prognostic marker.

RespPSI/PORT Score

Stratifies CAP severity. Classes I-II: outpatient; Class III: short admission or observation; Classes IV-V: inpatient/ICU.
