Calculation pulmonary vs systemic vascular resistance

Clinical - Cardiovascular, Physiology - Cardiovascular

Vascular Resistance

  •  PVR = 80*(PAP – PCWP)/CO, normal 100-200 dyn-s/cm5
  •  SVR = 80*(MAP – CVP)/CO, normal 900-1200 dyn-s/cm5

 Note that normal PA_systolic is 1/8th systemic SBP , and that pulmonary hypertension is defined as PA_systolic is > 1/4 systemic.
