\[RVSW=(MPAP-CVP)*SV*0.0136\]
Variables
RVSWright ventricular stroke work (g·m/beat)
MPAPmean pulmonary artery pressure (mmHg)
CVPcentral venous pressure (mmHg)
SVstroke volume (mL/beat)
Description
What is this formula?
Right Ventricular Stroke Work (RVSW) estimates the mechanical work performed by the right ventricle during a single heartbeat. It reflects the energy required to pump blood through the pulmonary circulation.
When to use it
Use this formula in pulmonary hypertension assessment, right ventricular failure evaluation, cardiac surgery, and advanced hemodynamic monitoring.
Example
Data:
MPAP = 25 mmHg
CVP = 5 mmHg
SV = 75 mL/beat
Formula:
RVSW = (MPAP − CVP) × SV × 0.0136
Substitution:
RVSW = (25 − 5) × 75 × 0.0136
Result:
RVSW = 20.40 g·m/beat
