Calculates pulmonary artery pulse pressure from systolic and diastolic pulmonary artery pressures.
Overview
Calculates pulmonary artery pulse pressure from systolic and diastolic pulmonary artery pressures.
Clinical Significance
Describes pulmonary artery pulsatility and contributes to calculations of pulmonary compliance and right-heart performance.
When to Use
- Use when the required measurements are available, reliable and clinically relevant.
How It Is Calculated
- PAPP = PASP − PADP.
Interpretation
- Describes pulmonary artery pulsatility and contributes to calculations of pulmonary compliance and right-heart performance.
Worked Example
Enter valid values in the displayed units. MedicalC then applies: PAPP = PASP − PADP.
Limitations
- The result does not establish a diagnosis or mandate treatment.
- Measurement error may be more important than arithmetic precision.
- Published thresholds may differ between populations and settings.
Clinical Pearls
- Document the source values and units with the final result.
- Review trends rather than isolated values where appropriate.
Common Mistakes
- Using the wrong unit.
- Combining values from different time points.
- Applying the result outside the intended measurement or clinical context.
