Cardiology - Mean Arterial Pressure
How to determine mean arterial pressure ?
Mean arterial pressure is identified by considering how much blood the heart pumps into the arterial system at a given time ( cardiac output) and how much resistance that the arteries have to the flow of the blood ( total peripheral resistance).
Mean arterial pressure ( MAP ) = Cardiac output (CA) x Total Peripheral Resistance ( TPR)
Mean arterial pressure can also be calculated by using the following mathematical equation
MAP = 1/3 systolic blood pressure + 2/3 diastolic blood pressure
Cardiac output is the primary determinant of systolic blood pressure.
Total peripheral resistance is the primary determinant of diastolic blood pressure
1/3rd of cardiac cycle is in the systolic phase and 2/3 of the cardiac cycle is in the diastolic phase.
