Mean arterial pressure

Mean Arterial Pressure (MAP) is a term used in medicine to describe the average blood pressure in an individual's arteries during one cardiac cycle. It is considered a better indicator of perfusion to vital organs than systolic blood pressure (SBP).

Definition

The Mean Arterial Pressure is the average pressure in a patient's arteries during one cardiac cycle. It is considered a crucial factor in terms of the overall health and well-being of the individual. The MAP can be calculated using the formula: MAP = [SBP + (2 x DBP)] / 3, where SBP is the systolic blood pressure and DBP is the diastolic blood pressure.

Importance

The MAP is an important measure as it is used to represent the perfusion pressure seen by organs in the body. It is believed to correlate with the risk of heart disease and other cardiovascular complications. A MAP that is too high or too low can be indicative of medical issues such as hypertension or hypotension, respectively.

Measurement

The MAP is typically measured using a sphygmomanometer, a device that measures blood pressure. It can also be measured directly using an arterial line, or indirectly using a non-invasive method such as a blood pressure cuff.

Clinical significance

The MAP is used in medicine to guide treatment decisions in patients with hypertension, hypotension, and other cardiovascular diseases. It is also used to monitor the effectiveness of treatments for these conditions.
