| name | Right ventricular Intrachamber systolic pressure estimated by US | ||
| description | Right ventricular systolic pressure (RVSP) can be estimated based on the the peak tricuspid regurgitant jet velocity (TR V), using the simplified Bernoulli equation, along with the estimated right atrial pressure (RAP) [LOINC: 82337-7], which is itself estimated based on the diameter of the inferior vena cava.

Fully-Specified Name | |||
| component | Intrachamber systolic | ||
| property | Pres = Pressure | ||
| 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 | Heart.ventricle.right | ||
| 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 | ||
