The MAP calculator measures the systolic blood pressure (SBP) and diastolic blood pressure (DBP), and their mean arterial pressure (MAP).

MAP  calculation is an indication for the doctors and they use it to check whether there is enough blood supply to your organs or not.

Let’s look at the various terms related to the concept of the MAP.

What is Mean Arterial Pressure (MAP)?

The MAP (Mean Arterial Pressure) is the average pressure in the patient’s arteries and veins during one Cardiac cycle. MAP is a better indicator of perfusion or normal blood transmission to the vital organs. We simply can’t input the systolic and diastolic pressure to find the perfusion of blood transmission. You need to calculate mean arterial pressure to describe, whether the blood pressure is normal or not. 

Research has shown that the map calculation provides us with a better picture of perfusion or transmission of blood. The true MAP calculation can only be determined by invasive monitoring and complex calculation. The blood pressure map calculator provides us with an easy-to-find complex calculation instantly. You need to enter the (SBP) and the diastolic blood pressure (DBP).

How Do You Calculate Mean Arterial Pressure?

The MAP is the average pressure of the arteries during one cardiac cycle. The MAP is considered a better indicator of a person’s blood circulatory system than simply measuring the Systolic Blood Pressure(SBP). Calculating maps is especially useful for patients in emergencies and in special care. The map calculation formula is simple to understand and it is essential to find the transmission of blood through our blood arteries. If you want to make a map blood pressure formula easy for yourself, then just find the Plus rate and divide it by “3” plus add the 

How to Calculate MAP?

MAP = DP + 1/3(SP – DP) 

MAP = DP + 1/3(PP)


MAP: Mean Arterial Pressure

DP: Diastolic Pressure 

SP: Systolic Pressure

PP=Pulse Pressure 

The Cardiac Output is exactly the amount or the quantity of blood, which the heart pumps. The MAP calculation is a perfect way to find our Cardiac Output. The Cardiac Output depends upon the Systemic Vascular Resistance(SVR) of the blood circulatory system. The SVR calculator provides an irresistible platform to find Systemic Vascular Resistance(SVR) for the patients.

MAP Ranges for Patients:

The normal MAP ranges of the blood pressure for Diastolic and Systolic are (60-80) and(100-120) for everyone. The diastolic range is lower compared to the systolic range. For patients calculating mean arterial pressure becomes crucial to diagnose their blood transmission. The blood actually coming from the heart have various MAP ranges:

The MAP ranges can be classified into the following level:

Very Low-Level-MAP:

MAP under 60 mmHg comes under this level, and at this point, the systolic and diastolic pressure is at the lowest level. The patient is in critical condition, and the map blood pressure calculator indicates both the systolic and diastolic range. Here it is sure both the DP and the SP values are not going to fall in the range and it crosses the lower level ranges. The Pulse Pressure is very low as we are touching the lower touching limits.

Low-Level MAP:

The low range lies between 60 to 70 mmHg, and it is possible that DP and the SP values may fall in the lower range. It is certain that one of the value falls under the normal range of systolic and diastolic pressure. This makes the task easy when using the BP map calculator for mapping your blood pressure. The map pressure calculator indicates when your blood pressure mapping is in the lower range.

Normal MAP:

The normal map value is between 70 to 100 mmHg and it is certain both  DP(60-80) and SP(100-120) values would fall in the normal range of systolic and diastolic values. When you calculate a map for a patient, then it is easy to predict that the range is on the normal side.

High MAP: 

MAP values above 100 mmHg come under this level and this causes stress on our hearts. It is certain that one of the DP(60-80) and SP(100-120) is touching the higher range. The map calculation of blood pressure indicates this fact. It is a special case of hypertension or an extraordinary heartbeat and we need to consult the doctor at once.


Category Systolic BP,


Diastolic BP,


Optimal < 120 < 80
Normal 120–129 80–84
High normal 130–139 85–89
Grade 1 hypertension 140–159 90–99
Grade 2 hypertension 160–179 100–109
Grade 3 hypertension ≥ 180 ≥ 110
Isolated systolic hypertension ≥ 140 < 90


You may find map calculator supportive to find Map values and a better indicator of the blood transmission rate.


Calculate the MAP for the systolic pressure 120mmHg and the diastolic pressure 80mmHg.


The systolic pressure=120 mmHg

The diastolic pressure=80 mmHg

The map calculation formula

MAP = DP + 1/3(SP – DP) 

MAP = 80 + 1/3(120 – 80) 

MAP = 93.333 mmHg

Plus rate= SP – DP=120 – 80=40 mmHg

Calculating mean arterial pressure by mean arterial pressure calculator is simple and informative.

Working of the MAP Calculator:

You can measure map BP by inserting the following input value:


  • Enter the Systolic blood pressure 
  • Enter the Diastolic blood pressure 
  • Hit the calculate button to find MAP


The MAP calculator calculate the values described below:

  • The Mean Arterial Pressure
  • The Plus Pressure 


What is systolic and diastolic pressure?

The systolic and diastolic pressure actually represents the contraction and relaxation of the heart chambers. The map calculator makes it easy for users to find the Mean Arterial Pressure of a person on the basis of the systolic and diastolic pressure.

What is pulse pressure?

The pulse pressure is the difference between systolic pressure and diastolic pressure. The map calculator BP the process easy to find the pulse pressure automatically when we are entering the systolic and diastolic pressure.

What is the result of high mean arterial pressure?

A mean arterial pressure in the high range could be an indication that the heart has to work much harder than it should. This is causing stress on the heart, high MAP can result in advanced heart disease, blood clots, heart attack, and stroke.

What is the normal heart rate?

The normal systolic pressure is 120 mmHg and diastolic pressure is 80mmHg. The mean arterial pressure for this systolic and diastolic pressure is around 93 mmHg when measured by the mean arterial pressure calculator.

How to calculate mean arterial pressure?

We calculate MAP(Mean Arterial Pressure), first we need to find the pulse rate and then divide it by ⅓. Then add Diastolic pressure to the answer to find the MAP, we can find a map by the map calculator.


It is just too essential to calculate the MAP value of a patient, as it is one of the most obvious indications of the blood circulatory system. The MAP calculator makes the task simple for the Physician as a normal MAP value indicates the person is healthy.
