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.
