Formel

CO = HR × SV. MAP = DBP + (SBP − DBP) / 3. SVR = (MAP − CVP) × 80 / CO.

Häufig gestellte Fragen

Is the MAP formula exact?

It is the standard clinical approximation for heart rates around 60–100 bpm. At very high rates the diastolic portion shortens and the simple 1/3 weighting underestimates MAP.

Why is SVR multiplied by 80?

To convert (mmHg · min / L) into the Woods unit dyn·s·cm⁻⁵ used in intensive care hemodynamics.
