Compute Mean Arterial Pressure (MAP)

Computes mean arterial pressure (MAP) based on diastolic and systolic blood pressure. Optionally heart rate can be used as well.

compute_map(diabp, sysbp, hr = NULL)

Arguments

diabp

Diastolic blood pressure

A numeric vector is expected.

Default value

none

sysbp

Systolic blood pressure

A numeric vector is expected.

Default value

none

hr

Heart rate

A numeric vector or NULL is expected.

Default value

NULL

Value

A numeric vector of MAP values

Details

$$\frac{2DIABP + SYSBP}{3}$$ if it is based on diastolic and systolic blood pressure and $$DIABP + 0.01 e^{4.14 - \frac{40.74}{HR}} (SYSBP - DIABP)$$ if it is based on diastolic, systolic blood pressure, and heart rate.

Usually this computation function can not be used with %>%.
