    Transcript
    Hi, my name is Jill Beavers-Kirby and today we're going to be talking about Hemodynamics. So how do we monitor hemodynamics? This system was something a called a pulmonary arterial catheter, or you'll also hear it referred to as a PA catheter. This catheter is inserted under sterile technique by a physician. The brand name that most facilities use is by Swan-Ganz. It's a hyphenated name. The Swan-Ganz catheter has several ports that's used to monitor several different parameters of heart function and central circulation. The catheter is inserted into a large vein, such as the internal jugular, the subclavian, and it will terminate in the pulmonary artery. That's a very important thing to remember. So remember, the tip of the catheter ends in the pulmonary artery. That's why it's called a pulmonary arterial catheter. So one thing we can measure with a Swan-Ganz or PA catheter is the central venous pressure. This is the measure of the blood pressure in the right atrium and the vena cava and it's from the proximal lumen of the PA catheter. I'm not going to review with you all the normals of all these measurements, these are noted on the slides, but you should know them for your test. So why do we need to measure the central venous pressure or CVP? This can tell us how the right side of our heart is functioning. It can tell us systemic fluid status. We can also use central venous pressures to know if we need to give large amounts of fluid. And we can also use the central venous port to draw blood, to take blood tests on patients. So your central venous pressure can be elevated or higher than normal when you have too much fluid in your venous system. This increases your...
