LOINC Code 8833-6: Pulmonary vascular Resistance index by Indicator dilution

8833-6 is a LOINC code used to identify Pulmonary vascular Resistance index by Indicator dilution in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Hemodynamic resistance/Body surface area. It is commonly used with the system or sample type Pulmonary vasculature.
