Describe how a pulmonary artery catheter is inserted.
What will be an ideal response?
The pulmonary artery catheter is usually inserted into either the subclavian or internal jugular vein. From there, it is advanced to the superior vena cava and right atrium. The balloon is then inflated and the blood flow moves the catheter with its inflated balloon just as the wind moves a sail. The catheter proceeds to the right ventricle and into the pulmonary artery where it will eventually "wedge" in a smaller branch of the pulmonary artery. The balloon is then deflated and the catheter stabilized in place.
