Mean Arterial Pressure

Card Catalog

 

 

 

Mean Arterial Pressure (MAP) is a calculated estimate of the average arterial blood pressure (BP) used to supply your organs with blood as indicated by the green points in the graph.  If MAP is too high, organs could be damaged; especially your eyes and kidneys due to their delicate structure.  If MAP is too low, insufficient blood flow may affecting organ functionality. 

 

MAP = DP + PP/3

 

Pulse Pressure (PP) is simply the calculated difference between Systolic Pressure (SP) and Diastolic Pressure (DP):

 

PP = SP – DP

 

(See Trax News Article #11 in the Library: “Pulse Pressure”).

 

The critical limits for MAP are 60 to 110 mmHg depending on your health.  Below 60 mmHg, your organs may not receive enough blood to function properly due to low BP.  Above 110 mmHg, your organs may be damaged due to high BP.

 

*** CAUTION ***

 

This method of estimating MAP is only valid when your BP is measured using Resting BP Procedures (See Trax News Article #2 in the Library: “Don’t Forget to Rest ”).

 

Due to BP variability, always average five (5) or more MAP results for the best estimate of this parameter.

 

If you feel that your MAP is too high or too low, please check with your MD to verify results.

 

I hope this brief explanation helps you understand what MAP is and why it is included in bp Trax.
