Mean Arterial Pressure

$\mathrm{MAP}=\mathrm{DP}+\frac{\mathrm{SP}-\mathrm{DP}}{3}$

• $\text{DP}$ is the diastolic pressure
• $\text{SP}$ is the systolic blood pressure
• The formula isn’t $\frac{\mathrm{SP}+\mathrm{DP}}{2}$ because a typical cardiac cycle spends about $\frac{1}{3}$ of its time in diastole vs. $\frac{2}{d}$ of its time in systole
