Pulmonary vascular resistances (PRV)

PRV (dynes.s/cm2)

(PAPm-Wedge) x 79.9 /cardiac output.

indexed PRV (dynes.s/cm2/m2)

PRVi = PAPm-Wedge) x 79.9 /cardiac index.

Normal : 20-130 dynes.s/cm2 ou 0.25-1.6 Wood unit.

1 Wood unit (WU) = 79 x dynes.s/cm2.

Definitions

• PAP= mean arterial pulmonary pressure.
• Wedge= pulmonary wedge pressure.
