Question 1

Pulse pressure formula

Answer 1

Difference between systolic & diastolic blood pressure

120-80 = 40 pulse pressure

Question 2

MAP ( Mean Arterial Pressure ) formula

Answer 2

Diastolic pressure + 1/3 pulse pressure

Question 3

Cardiac Output formulas

Answer 3

Stroke Volume x Hr = CO

Resting CO= 70mL/beat x 75bpm= 5,250mL/min

Max CO= 160bpm x 150mL =24 L/m

Cardiac Reserve= Max CO - Resting CO
24 - 5.25 = 18.75 L/m
