BAP-65 Score for Acute COPD Exacerbation

Stratifies risk of in-hospital mortality and need for mechanical ventilation in acute COPD exacerbation.

B — BUN ≥ 8.9 mmol/L (≥ 25 mg/dL)?

A — Altered mental status?

P — Pulse > 100 bpm?

Age ≥ 65 years?

BAP-65 Score (Class I)/ 3

Class I — Very low risk

Estimated in-hospital mortality: ~0.3%. Standard ward management appropriate. Optimise bronchodilators (SABA + SAMA), controlled oxygen therapy (target SpO₂ 88–92%), and systemic corticosteroids (prednisolone 30–40 mg for 5 days). Antibiotics if purulent sputum or clinical signs of infection.

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.

RespSTOP-BANG

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