Calculation Concerning the Periodic Arterial Pulse Using Rs

Calculation Concerning the Periodic Arterial Pulse Using R_s = 17.5 mm Hg/(liter/min), C_sa = 0.00175 liters/mm Hg (see Exercise 1.17), Delta V_0 = 0.070 liters, and T = (1/80) min, evaluate Theta = exp (-T/(R_s C_sa)) and then use Theta to evaluate the systolic pressure, the diastolic pressure, the pulse pressure, and the mean arterial pressure in the periodic case.

Solution

= exp(-T/RsCsa)= exp(-0.0125/17.5*0.00175)= -0.0125/0.30625= e-0.040816= logarithm of 10-0.0408 = 0.9592

systolic pressure (S.P)= 120-0.9592 =119.0408

Diastolic pressure (D.P) = 80- 0.9592 = 79.0408

Pulse Pressure= S.P - D.P=119.0408-79.0408 =40

Mean Arterial Pressure (MAP)= [(2* D.P)+ S.P]/3 = 58.0816*119.0408/3 =18818.16012928/3= 6272.72
