📈 Mean Pulmonary Artery Pressure (mPAP)

UseWhen to use: RHC / PA catheter waveforms when a catheter-averaged mean is not displayed.

Loading calculator…

StrataElevated mPAP is a PH hemodynamic cue — always phenotype with PAWP and PVR.

LimitsWhen not to use: severe PR / damping. · Pitfall: echo PASP ≠ cath mPAP. · Thresholds are era-dependent.

(PASP+2×PADP)/3.

When to use

When to use: RHC / PA catheter waveforms when a catheter-averaged mean is not displayed.

How it works

mPAP = (PASP + 2×PADP) / 3.

Key points

  • (PASP+2×PADP)/3.
  • Prefer averaged mean.
  • Next: PAWP / PVR.

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.

PA systolic (PASP)35 mmHg
PA diastolic (PADP)18 mmHg

→mPAP23.7mmHg

  • PA pulse pressure：17.0 mmHg
  • Cue：>20 mmHg — elevated mPAP band (PH definitions are guideline-era dependent)

FAQ

Frequently asked questions

Does Mean Pulmonary Artery Pressure (mPAP) 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 Mean Pulmonary Artery Pressure (mPAP) calculated in practice? Can you show a worked example?
Inputs: PA systolic (PASP) 35 mmHg, PA diastolic (PADP) 18 mmHg → Result: mPAP 23.7 mmHg（PA pulse pressure: 17.0 mmHg, Cue: >20 mmHg — elevated mPAP band (PH definitions are guideline-era dependent)）
