📈 Transpulmonary & Diastolic Pressure Gradients
UseWhen to use: classifying pre- vs post-capillary PH components.
StrataDPG ≥7 mmHg often flags a pre-capillary component cue alongside PVR.
LimitsWhen not to use: poor PAWP quality. · Pitfall: TPG alone without PVR/CO. · Not a standalone PH diagnosis.

When to use
When to use: classifying pre- vs post-capillary PH components.
How it works
TPG = mPAP − PAWP; DPG = dPAP − PAWP.
Key points
- TPG & DPG.
- Pair with PVR.
- Next: PH workup.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Mean PA pressure (mPAP) | 35 mmHg |
|---|---|
| Diastolic PA pressure (dPAP) | 22 mmHg |
| PAWP / PCWP | 14 mmHg |
→TPG21.0mmHg
- DPG：8.0 mmHg
- Cue：DPG ≥7 — pre-capillary / combined PH cue (with mPAP/PAWP context)

FAQ
Frequently asked questions
- Does Transpulmonary & Diastolic Pressure Gradients upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Transpulmonary & Diastolic Pressure Gradients calculated in practice? Can you show a worked example?
- Inputs: Mean PA pressure (mPAP) 35 mmHg, Diastolic PA pressure (dPAP) 22 mmHg, PAWP / PCWP 14 mmHg → Result: TPG 21.0 mmHg（DPG: 8.0 mmHg, Cue: DPG ≥7 — pre-capillary / combined PH cue (with mPAP/PAWP context)）
