WebMay 4, 2024 · Four valves in the heart keep blood flowing in the right direction. Disease or damage to any of the valves may interrupt blood flow and cause the heart chambers to get larger. High blood pressure (hypertension). If you have high blood pressure, the heart may have to pump harder to deliver blood to the rest of the body. Right atrial pressure (RAP) is the blood pressure in the right atrium of the heart. RAP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system. RAP is often nearly identical to central venous pressure (CVP), although the two terms are not identical, as a … See more Factors that increase RAP include: • Hypervolemia • Forced exhalation • Tension pneumothorax • Heart failure See more • Pulmonary capillary wedge pressure • Jugular venous pressure • Central venous pressure See more • Cardiovascular Physiology Concepts • Cardiovascular Physiology • Right+Atrial+Pressure at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more
