Pulmonary Vascular Resistance (PVR)

              MPAP   mmHg

              PAOP   mmHg

                 CO    L/min

PVR =      dynes/sec x cm^-5 (or)
                 Woods Units

PVR    =  [(MPAP -PAOP)/CO]*80 dynes/sec x cm^-5
               (or) (MPAP - PAOP)/CO Woods Units
Normal: 150-250 dynes/sec x cm^-5 (or) 1-3 Woods Units
