19218-7
LaboratoryOxygen content in Arterial 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 59274-1). 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 term and LOINCs 34163-6 and 19219-5.
