MAP = DBP + 1/3 × (SBP - DBP)

Here are the calculations for all three readings:

1st Reading: SBP = 116, DBP = 72 MAP = 72 + 1/3 × (116 - 72) = 72 + 1/3 × 44 = 72 + 14.67 = 86.67 mmHg

2nd Reading: SBP = 118, DBP = 74 MAP = 74 + 1/3 × (118 - 74) = 74 + 1/3 × 44 = 74 + 14.67 = 88.67 mmHg

3rd Reading: SBP = 114, DBP = 70 MAP = 70 + 1/3 × (114 - 70) = 70 + 1/3 × 44 = 70 + 14.67 = 84.67 mmHg

All three MAPs are within the normal range (70-100 mmHg). Note that the PP column in the image was left blank - all three pulse pressures are 44 mmHg.

From the image, the readings are:

Lying: SBP = 130, DBP = 70 MAP = 70 + 1/3 × (130 - 70) = 70 + 1/3 × 60 = 70 + 20 = 90 mmHg

Immediately Standing: SBP = 140, DBP = 90 MAP = 90 + 1/3 × (140 - 90) = 90 + 1/3 × 50 = 90 + 16.67 = 106.67 mmHg

5 mins after Standing: SBP = 120, DBP = 70 MAP = 70 + 1/3 × (120 - 70) = 70 + 1/3 × 50 = 70 + 16.67 = 86.67 mmHg

From the image, the readings are (exercise test):

Lying: SBP = 120, DBP = 90 MAP = 90 + 1/3 × (120 - 90) = 90 + 1/3 × 30 = 90 + 10 = 100 mmHg

Immediately after exercise: SBP = 140, DBP = 70 MAP = 70 + 1/3 × (140 - 70) = 70 + 1/3 × 70 = 70 + 23.33 = 93.33 mmHg

5 mins after exercise: SBP = 120, DBP = 70 MAP = 70 + 1/3 × (120 - 70) = 70 + 1/3 × 50 = 70 + 16.67 = 86.67 mmHg
