How Is Pulmonary Artery Pressure Measured?

Checking pulmonary artery (PA) pressure is a crucial step in diagnosing conditions like pulmonary hypertension. The most accurate method is right heart catheterisation—a procedure performed in specialist centers across the country.

This test involves inserting a thin, flexible catheter into a vein—usually in the neck, groin, or arm—and carefully guiding it through the heart and into the pulmonary artery. Once in place, the catheter measures the blood pressure directly in the right side of the heart and the pulmonary circulation. Unlike non-invasive tests such as echocardiograms, which can estimate PA pressure, right heart catheterisation provides definitive, real-time readings.

The procedure is typically done under local anesthesia and takes about 30 to 60 minutes. Patients remain awake but relaxed, allowing the medical team to communicate throughout. While it sounds invasive, it’s generally safe when performed by experienced specialists, with minimal risk of complications like bruising or infection at the insertion site.

Right heart catheterisation isn’t just for diagnosis—it also helps assess how well treatments are working and guides further management. For people with symptoms like unexplained shortness of breath or fatigue, especially when other heart or lung conditions are suspected, this test can be a turning point in understanding what’s truly going on.

Because of its precision, right heart catheterisation remains the gold standard for measuring pulmonary artery pressure, helping doctors confirm or rule out serious underlying issues. If your doctor recommends this test, it’s likely to get a clear picture of your heart’s function and ensure you receive the most appropriate care.
