1. Blood Pressure and Mean Arterial Pressure
It’s all about perfusion!

2. Blood Pressure – which is better?
MAP 62
BP 105/40 90/50 80/53
From a perfusion perspective, all 3 are equal.

3. Mean Arterial Pressure
Mean Arterial Pressure (MAP) is a term used in medicine to describe an average blood pressure in an individual
Calculated by: [Systolic + (2x Diastolic) ] / 3
120/80 = [100 + (2x80)]/3 = ( )/3 = 260/3 = 87

4. Why is MAP important? Perfusion MAP 65-75 Kidney Heart Brain >65
>50-55
Kidney Heart Brain
A MAP of greater than 65 will keep all these organs perfused

5. Why is MAP important?
So during a resuscitation you want to be continuously aware of the patient’s MAP (along with oxygen saturations etc)
