Transpulmonary & Diastolic Pressure Gradient
Transpulmonary (mean PAP − PCWP) and diastolic (PA diastolic − PCWP) pressure gradients (Naeije 2013); with PCWP > 15 mmHg a DPG ≥ 7 marks a combined pre-/post-capillary pulmonary-hypertension pattern.

Example
- Mean PA pressure
- 40 mmHg
- PA diastolic pressure
- 30 mmHg
- Mean PCWP
- 20 mmHg
Result: TPG 20, DPG 10 mmHg — with PCWP > 15, DPG ≥ 7 marks a combined pre-/post-capillary component.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Formulas
- TPG = mean PAP − PCWP; DPG = PA diastolic − PCWP.
- Classification
- TPG > 12 flags a pulmonary-vascular component; with PCWP > 15, DPG ≥ 7 marks combined pre-/post-capillary PH.
What you enter
- Mean PA pressure
- PA diastolic pressure
- Mean PCWP
