namePulmonary artery End diastolic blood pressure by Cardiac catheterization
descriptionDiastolic pulmonary artery pressure (dPAP) is used with pulmonary artery wedge pressure (PAWP) to help distinguish post-capillary pulmonary hypertension from combined post- and pre-capillary pulmonary hypertension associated with left heart failure. The diastolic pressure gradient (DPG) is calculated as dPAP minus PAWP, and is an alternate to the transpulmonary pressure gradient (TPG), which is calculated as the mean pulmonary artery pressure (mPAP) minus PAWP. An elevated DPG or TPG indicates that the increase in pulmonary pressure is not solely due to increased PAWP (post-capillary), but rather has a pre-capillary component as well, as reflected in an dPAP/mPAP increase out of proportion to PAWP.

Fully-Specified Name

componentIntravascular end diastolic
propertyPres  =  Pressure
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemPulmonary artery
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
methodCardiac catheterization
