19220-3
LaboratoryOxygen content in Venous blood
Definition
Be very careful about mapping to this term. We cannot confirm that anyone reports it in this manner - perhaps as number of molecules of oxygen in a given volume. We also cannot confirm that there is a method for measuring oxygen content directly (rather than as the calculation given under the term 60841-4). Likewise we cannot prove that such an approach does not exist. However, all of the usages that we know about are based on calculations. So be very careful about mapping to oxygen saturation terms that are not derived from calculations, e.g. this terms and LOINCs 34163-6, 19218-7 and 19219-5.

What does 19220-3 measure?
This code measures Oxygen content in BldV. It belongs to the CHEM class in the LOINC classification.
What is LOINC?
LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
