Mean Arterial Pressure

The mean arterial pressure (MAP) is the average blood pressure exerted by the blood on the walls of arteries in one full cycle of the heartbeat.

To understand about mean arterial pressure further, it is essential that we learn some basics of blood circulation and heart functioning.

We all know that in human beings and for that matter in all living beings in general, the heart is an essential organ that functions throughout the life of the organism. The heart keeps the blood circulating across the body and is necessary for the supply of oxygen for the lungs.

Consider one single cycle of heartbeat for our understanding. It contains two cycles:

  • Diastole: When heart muscle relaxes (opens or expands) and refills the blood into it
  • Systole: When it contracts and pushes the blood into the arteries to carry across the body

Now, you might have obtained a picture that during diastole the pressure is less because the heart is expanding and vice versa during systole. For a healthy person, the systolic pressure should be less than 120 and diastolic pressure should be less than 80. Any variation in these numbers indicate abnormalities in blood pressure as explained here:

  • Low blood pressure: Systolic pressure is between 120 and 139
    Diastolic pressure is between 80 and 89
  • High blood pressure: Systolic pressure above 139
    Diastolic pressure above 89

Mean Arterial Pressure and its Significance

Simply put, mean arterial pressure is the average in the arteries for one heartbeat or one cardiac cycle.

MAP plays a significant role in and provides the health data of a human. It is measured in mm of Mercury (mmHg). It is a critical key for doctors to estimate the blood flow, resistance and supply of blood to the entire body of a human.

A normal human will have 1 MAP value of 70-100 mmHg. Based on its value and range, doctors estimate the chances of occurrence of various dangerous ailment as explained here:

  • A high MAP that is over 100 mmHg indicates that the heart is working harder to pump the blood. It means the probability of heart attack, kidney failure, and heart failure.
  • A low MAP that is below 60 mmHg indicates that the blood is not adequately being pumped to all the organs of the body. This can be an indication of stroke and internal bleeding.
Lowering blood pressure in 24 hours following a stroke can reduce chances of brain damage.

How to maintain healthy blood pressure?

  • Reduce salt intake. Stop eating all junk food, processed foods, and prepared foods, as these are very high in sodium content.
  • Exercising helps in the release of nitric acid that helps to relax blood vessels and in smooth blood circulation.
  • Healthy food intake, containing fibrous foods such as fruits and vegetables, fatless dairy, egg whites, and lean meat, nuts and whole grains helps in maintaining healthy blood pressure.
  • Weight adds to the pressure of heart and makes it work harder to pump blood. Losing weight helps reduce the strain on the heart and thus keeps it healthy.
  • Alcohol raises blood pressure and does no good to the heart. It is suggested that drinking is kept at bay for a healthy heart.
  • Smoking stuffs blood vessels with nicotine, which chokes the blood vessels and creates hurdles in the supply of oxygen across the body.

Trust is like blood pressure. It is silent, vital to good health; and if abused it can be deadly. - Frank Sonnenburg
