These numbers are related to various measurements used to assess pulmonary hypertension (PH). Here's a breakdown of what each value represents:

- RA (Right Atrium) 20 mm Hg: This is the pressure in the right atrium of the heart. Elevated RA pressure can indicate right heart dysfunction
- RV (Right Ventricle) 45/24 mm Hg: Show Full Answer

These numbers are related to various measurements used to assess pulmonary hypertension (PH). Here's a breakdown of what each value represents:

- RA (Right Atrium) 20 mm Hg: This is the pressure in the right atrium of the heart. Elevated RA pressure can indicate right heart dysfunction.
- RV (Right Ventricle) 45/24 mm Hg: These are the systolic and diastolic pressures in the right ventricle. Elevated pressures can suggest pulmonary hypertension.
- PA (Pulmonary Artery) 45/20 mm Hg, Mean 28 mm Hg: These are the systolic and diastolic pressures in the pulmonary artery, with a mean pressure of 28 mm Hg. A mean pulmonary artery pressure (mPAP) greater than 20 mm Hg can indicate PH.
- PCWP (Pulmonary Capillary Wedge Pressure) 20 mm Hg: This pressure reflects left heart function. A normal PCWP is 15 mm Hg or less. Elevated PCWP can indicate left heart disease.
- PA SAT (Pulmonary Artery Saturation) 73%: This is the oxygen saturation in the pulmonary artery. Lower values can indicate poor oxygenation.
- CO/CI (Cardiac Output/Cardiac Index) 8.7 L/min / 3.4 L/min/m² (Fick method): These values measure the amount of blood the heart pumps per minute and per square meter of body surface area. The Fick method is a way to calculate these values.
- PVR (Pulmonary Vascular Resistance) 1 Wood unit: This measures the resistance the blood faces when flowing through the lungs. A normal PVR is 0.3 to 2 Wood units. People with PH typically have a PVR higher than 2 Wood units.

These measurements help healthcare providers classify the type and severity of PH and determine the best treatment plan. If you have any concerns or need further clarification, it's best to discuss these results with your healthcare provider.
