Blood Pressure, Dr. D. Penney



Calculation of Compliance

Recall: Compliance = Change in Vol. / Change in Press.

For Aorta:

3 ml / 300 mmHg = .01 ml / mmHg
or E = 1 / .01 = 100

For Vena Cava (1):

2 ml / 8 mmHg = .25 ml / mmHg
or E = 1 / .25 = 4

For vena Cava (2):

.75 ml / 16 = .047 ml / mmHg
or E = 1 / .047 = 21.3
