Question 28

SVR

Answer 28

Major part of afterload that has to be overcome to eject blood from LV SVR= (MAP-RAP)/ CO x 80 NORMAL: 800-1200 dynes/sec/cm2 or Dynes x sec-1x cm-5

Determines pressure of the pulm artery distal to the occlusion on the Swan shows left atrial pressure and with normal Mitral it approximates left vent pressure/preload Normal: 8-15

Question 32

Mean Pulm art Pressure

Answer 32

MPAP= SPAP-DPAP/ 3 + DPAP | Normal: 10-20

Question 33
