WebThe normal value for α measured on in vitro mounted pulmonary resistive vessels is 2% change in diameter per mmHg change in pressure, and is remarkably constant in a wide spectrum of animal species [].It is interesting that the same distensibility α-value of 2% per mmHg has been recovered by the application of the distensibility model equation to … 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:
