Quizplus · Accepted Answer

The SvO2 level is measured in the distal lumen of a pulmonary artery catheter, which is located in the pulmonary artery. This lumen is designed specifically for blood sampling and analysis. The balloon inflation lumen is used for measuring pulmonary artery pressure, the proximal injectable port is used for administering medication, and the proximal infusion port is used for monitoring central venous pressure.
