Presentation transcript:

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

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

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 = (100+160)/3 = 260/3 = 87

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

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