Mean Arterial Pressure (MAP)

Description

Calculates the Mean Arterial Pressure (MAP), which represents the average arterial pressure during a single cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure alone.

Usage

calculate_map(systolic_bp, diastolic_bp)

Arguments

systolic_bp	Numeric. Systolic Blood Pressure in mmHg.
diastolic_bp	Numeric. Diastolic Blood Pressure in mmHg.

Details

The formula used is:

MAP = \frac{SBP + (2 \times DBP)}{3}

Value

A list containing:

Mean_Arterial_Pressure

The calculated MAP in mmHg.
