learn.whatIsHeading

Mean Arterial Pressure (MAP) is the average arterial pressure throughout one cardiac cycle. It represents the true perfusion pressure driving blood to vital organs.

נוסחה

Scale ratio: 1:50,000 means 1 cm map = 500 m reality | Distance on map × Scale = Actual distance

מדריך שלב אחר שלב

1MAP = (SBP + 2×DBP) / 3
2Alternative: MAP = DBP + (SBP − DBP)/3
3Normal MAP: 70–100 mmHg
4MAP < 60 mmHg: inadequate organ perfusion (emergency)

Worked Examples

קלט

SBP 120 mmHg, DBP 80 mmHg

תוצאה

MAP = (120 + 2×80) / 3 = 280/3 = 93.3 mmHg (Normal)
