PVR (Pulmonary Vascular Resistance) measures how much resistance blood faces when flowing from your lungs to your heart. A normal PVR range is between 0.3 and 2 Wood units (WU). When your PVR is elevated (above 2 WU), it means the blood vessels in your lungs have become thickened or narrowed, making it harder for blood to Show Full Answer

PVR (Pulmonary Vascular Resistance) measures how much resistance blood faces when flowing from your lungs to your heart. A normal PVR range is between 0.3 and 2 Wood units (WU). When your PVR is elevated (above 2 WU), it means the blood vessels in your lungs have become thickened or narrowed, making it harder for blood to flow through them properly.

An elevated PVR is one of the key measurements doctors use to diagnose and monitor pulmonary hypertension. Your doctor will use this number, along with other measurements, to determine how severe your condition is and whether your current treatments are working effectively. Regarding IFR (Inspiratory Flow Rate), this specific measurement is not covered in the provided search results, so it would be best to ask your healthcare provider to explain this particular result from your right heart catheterization report. They can provide the most accurate interpretation of your specific test results and what they mean for your treatment plan.
