The healthcare provider wants a svo2 level on a patient with a pulmonary artery catheter. The sample should be taken from the Distal lumen.
By measuring a SvO2 level in blood taken through the distal port of the PA line, it is possible to infer the amount of oxygen used by tissues.
The distal port is the lumen that opens up at the very tip of the catheter since it opens the furthest from the point of insertion. The proximal port is the one that is closest to the skin, while the medial port is the one that comes after it rearward.
Distal lumen for blood administration, drug delivery, and CVP monitoring. Only use the medial lumen for whole parenteral feeding as it minimizes the need for repeated venipunctures.
Blood draws are performed on the proximal, which is the brown cap.
