| name | Transpulmonary pressure gradient | ||
| description | Transpulmonary pressure gradient (TPG) is the difference between the mean pulmonary arterial pressure and left atrial pressure, which may be approximated by the pulmonary capillary wedge pressure; it can be used to identify intrinsic pulmonary vascular disease in left-heart conditions with correlated increased pulmonary venous pressure.

| component | Transpulmonary pressure gradient | ||
| property | PressDiff = Difference | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Pulmonary artery | ||
| scale | Qn = 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 | ||
