Mean Arterial Pressure (MAP) Calculator
This mean arterial pressure calculator calculates the mean arterial pressure of a person based on the person's systolic pressure and diastolic pressure, according to the formula shown above.
The mean arterial pressure is the average blood pressure during the entire cardiac cycle, taking into account systole and diastole.
Mean arterial pressure (MAP) is calculated based on 2 variables, the systolic pressure and the diastolic pressure.
The systolic pressure is the pressure that the heart produces during the systole cycle. The systole cycle is when the heart contracts. It is during systole that the greatest pressure from the heart is created. It is measured in unit millimeters of mercury (mmHg).
The diastolic pressure is the pressure that the heart produces during the diastole cycle. The diastole cycle is when the heart relaxes. Therefore, the pressure produced by the heart during diastole is always less than during systole. It is measured in mmHg.
The mean arterial pressure formula is calculated from the above formula because the heart is in diastolic twice as much as systole. Therefore, it must be accounted for 2 times more. The heart is in systole for 1/3 of the cycle and in diastole for 2/3 of the cycle. Therefore, each cycle is weighed based on this reason. The mean arterial pressure takes these 2 cycles weighed appropriately and averages them out. The mean arterial pressure, therefore, represents the average blood pressure during the entire cardiac cycle.
To use this calculator, a user enters in the systolic pressure and the diastolic pressure and clicks the 'Calculate' button. The resultant value will automatically be computed and shown. It is in unit millimeters of mercury (mmHg).
Electronic devices such as pacemakers can initiate the heart rate of an individual. Being that it initiates
heart beat, it influences stroke volume. Stroke volume is correlated to the amount of pressure the heart produces. Therefore,
electronic devices can affect systolic pressure and diastolic pressure, and, thus, the mean arterial pressure.
If a person has a systolic pressure of 120mmHg and a diastolic pressure of 80mL/beat, what is the mean arterial pressure of this individual.
So based on the values of the parameters, we use the equation MAP= ((2 * Diastolic Pressure) + Systolic Pressure)/3 and substitute in the values into the equation.
MAP= ((2 * 80) + 120)/3 * 70= 93.93 mmHg
