Important Formulas (Cardio)

Question 1

Blood Pressure

Answer 1

BP = CO x TPR = (HR x SV) x TPR

Question 2

Cardiac Output

Answer 2

CO = VR = VO2/AVO2

change in P/ R

CA = MAP - RAP/TPR

Question 3

Velocity

Answer 3

V = Q/A

q - blood flow
a -area

Question 4

Capacitance

Answer 4

C = V/P

Question 5

Reynolds Number

Answer 5

NR = pdv/n

p - density
d - diameter
v - velocity
n - viscocity

Question 6

Resistance

Answer 6

R = 8nl/pir4
