Equation

Question 1

Cardiac output

Answer 1

1) heart rate x stroke volume
2) Mean arterial BP/ Peripheral resistance
3) (diff between inspired and expired vol of o2)/ (o2 artery - o2 vein)

Question 2

Blood flow

Answer 2

1) Mean arterial blood pressure/peripheral resistance
2) area x velocity
3) (change in pressure x pir^4)/(8 x length x viscosity)

Question 3

Blood flow velocity

Answer 3

Surface area 1 x blood flow velocity 1 = Surface area 2 x blood flow velocity 2

Question 4

Peripheral resistance

Answer 4

(8 x length x viscosity)/(r^4 x pi)

Question 5

VO2

Answer 5

CO (arterial - venous)

Question 6

Ejection fraction

Answer 6

Stroke volume/ End-diastolic volume x 100

Question 7

Stroke volume

Answer 7

End diastolic volume - End systolic volume
