Pulmonary Hypertension Echocardiography • LITFL • CCC

Units for measuring vascular resistance are dyn·s·cm , pascal seconds per cubic metre (Pa·s/m ) or, for ease of deriving it by pressure (measured in mmHg) and cardiac output (measured in L/min), it can be given in mmHg·min/L. This is numerically equivalent to hybrid resistance units (HRU), also known as Wood units (in honor of Paul Wood, an early pioneer in the field), frequently used by pediatric cardiologists. The conversion between these units is: WebWood units: ( wud ), a simplified system for measuring pulmonary vascular resistance that uses increments of pressure. Measurement is made by subtracting pulmonary capillary wedge pressure from the mean pulmonary arterial pressure and dividing by cardiac output in liters per minute.
