Updated December 13, There are two main circuits in the body: the pulmonary circuit and the systemic circuit. The pulmonary circuit deals with blood between the heart and the lungs while the systemic circuit deals with the remaining parts of the body.
While most arteries carry oxygenated blood in the body, the pulmonary arteries carry de-oxygenated blood to the lungs. The main pulmonary artery, or the pulmonary trunk , transports de-oxygenated blood from the heart to the lungs.
The main pulmonary artery branches into both a right and left vessel. The right pulmonary artery carries blood to the right lung while the left pulmonary artery carries it to the left lung. This test may help understand the flow of blood within the heart affected by a birth defect.
High blood pressure in the lungs pulmonary hypertension Fat embolism clot that is blocking a blood vessel Pulmonary artery catheterization can help guide treatment. For example, it can help with: Complicated heart attacks Being unstable before or after surgery High blood pressure during the latter part of pregnancy severe preeclampsia Drug therapy Fluid levels in the blood vessels Burns Kidney failure Heart failure Sepsis Ventilator management What are the risks of pulmonary artery catheterization?
Possible risks include: Abnormal heart rhythms, some of which can be life threatening Right bundle branch block, which is often temporary Knotting of the catheter Rupture of the pulmonary artery Severely reduced blood flow to part of the lung Blood clots, which can cause a stroke Infection of the heart valves endocarditis Infections of the catheter Bleeding at the insertion site There is also a risk of inaccurate catheter placement.
How do I get ready for pulmonary artery catheterization? Your healthcare provider may want some other tests before the procedure. These might include: Chest X-ray Electrocardiogram, to look at heart rhythm Blood tests, to check general health Echocardiogram, to see blood flow through the heart and to view the fluid around the heart What happens during a pulmonary artery catheterization?
In general: You will be awake. You may be given medicine to make you sleepy before the procedure starts. Your vital signs will be closely watched. Healthcare providers will be prepared to step in if problems happen. Your healthcare provider will select the blood vessel where he or she will insert the catheter.
That might be in the arm, in the neck, in the groin, or below the collarbone. The provider injects a numbing medicine under the skin at the site where the catheter will be inserted. The provider uses a special needle to enter the blood vessel. He or she will put a wire into this vessel.
The provider puts a catheter over this wire, and then removes the wire. The provider moves a smaller catheter with a balloon at its tip through the blood vessel.
He or she will use the first tube as a guide. The provider moves the catheter to the right atrium. He or she then inflates the balloon at the tip. This is one of the rare arteries that carry deoxygenated blood; the other location is found within the fetus, where the umbilical arteries are. A variety of lung diseases can cause pulmonary hypertension , which is when the blood pressure increases in the pulmonary artery.
Pulmonary hypertension can be a consequence or a cause; for example, it may be a consequence of heart disease or a cause of right-ventricular heart failure. Other conditions that may cause pulmonary hypertension include scleroderma and pulmonary embolism. Scleroderma is a chronic systemic autoimmune condition that causes hardening of the skin and connective tissues.
A pulmonary embolism occurs when a substance from another place in the body blocks the left or right pulmonary artery. The lungs are the main part of your respiratory system.
