Final answer:

An SvO2 sample from a Swan Ganz catheter is drawn from the distal port, which is situated in the pulmonary artery, providing critical information on the body's oxygen delivery and consumption.

Step-by-step explanation:

The Swan Ganz catheter is a medical device used in critical care settings to measure various aspects of cardiac function, including pressures in different parts of the heart and lungs. One of the critical parameters that can be measured with a Swan Ganz catheter is the mixed venous oxygen saturation (SvO2), which reflects the balance between oxygen delivery and consumption in the body. To obtain an SvO2 sample from a Swan Ganz catheter, the blood is drawn from the distal port, which is the port farthest from the insertion site of the catheter, located in the pulmonary artery.
