What should mean arterial pressure be

Then divide by 3. In what other clinical situations do you monitor MAP? References: Surviving Sepsis Campaign. Accessed December 8, Smeltzer, S. Tags :. Log in to leave a comment Login or Register. Hamisu Nasiru Usman Bob So do i add 6 or 6x6 to MAP calc??

Since CVP central venous pressure is usually less than 10, the method mentioned here is close. Another way I have found to get a closer MAP is to add the heart rate divided by This is especially helpful when in more austere environments. Smithc Valuable information.

Fortunate me I discovered your web site by chance, and I am surprised why this coincidence didn't happened in advance! I bookmarked it. Mathew Adegbaju Thanks for this educative information.

Hillary Hunt, RN This was extremely helpful. Thank you. Why Use. The Mean Arterial Pressure can be calculated in all patients in which blood pressure values are obtained. Blood pressure targets have been shown to improve outcome in a number of conditions.

These include sepsis, trauma, stroke, intracranial bleed, and hypertensive emergencies. MAP is often used as a surrogate indicator of blood flow and believed to be a better indicator of tissue perfusion than SBP as it accounts for the fact that two thirds of the cardiac cycle are spent in diastole. A MAP of 60 mmHg or greater is believed to be needed to maintain adequate tissue perfusion. Systolic BP. Diastolic BP. Result: Please fill out required fields. Next Steps.

It is important to note that variables found in equation 1 are all interdependent. This means that changing one variable changes all of the others. From the aortic pressure trace over time see figure , the shape of the pressure trace yields a mean pressure value geometric mean that is less than the arithmetic average of the systolic and diastolic pressures as shown to the right.

For example, if systolic pressure is mmHg and diastolic pressure is 80 mmHg as shown in the figure , then the mean arterial pressure is approximately 93 mmHg using this calculation. At high heart rates, however, MAP is closer to the arithmetic average of systolic and diastolic pressure therefore, almost mmHg in this example because of the change in shape of the arterial pressure pulse it becomes narrower.
