Q: To measure Pulmonary artery pressure (wedge) via pulmonary artery catheter (PAC), when the balloon is inflated, it should not be inflated beyond the tip of the catheter.
A) True
B) false
Answer: B
While wedging the Swan-Ganz catheter (PAC), the balloon should be fully inflated to cover the tip of the catheter; otherwise, the risk of pulmonary artery rupture increases. Also, the measurement would not be correct.
