כיצד לחשב את Mean Arterial Pressure

learn.whatIsHeading

Mean Arterial Pressure (MAP) is the average blood pressure during one cardiac cycle, representing the true perfusion pressure to vital organs. MAP = (SBP + 2×DBP) / 3.

נוסחה

MAP = (SBP + 2×DBP) / 3

MAP: DBP + (pulse pressure / 3) — DBP + (pulse pressure / 3)
SBP: SBP value — Variable used in the calculation
DBP: DBP value — Variable used in the calculation

1MAP = (SBP + 2×DBP) / 3
2Alternatively: MAP = DBP + (pulse pressure / 3)
3Normal MAP: 70–100 mmHg
4MAP < 65 mmHg: organ perfusion compromised

Worked Examples

קלט

Blood pressure 120/80 mmHg

תוצאה

MAP = (120 + 160) / 3 = 93.3 mmHg (Normal)

Frequently Asked Questions

What is Map?
