What is considered normal right ventricular pressure (RV)?

The normal right ventricular pressure typically ranges from 15-25 mmHg during systole, with a diastolic pressure that can be around 0-5 mmHg. This range reflects the expected pressure exerted by the right ventricle as it contracts to pump deoxygenated blood into the pulmonary circulation. The systolic pressures are slightly lower than those of the left ventricle, as the right ventricle is responsible for a shorter distance to the lungs and, therefore, does not need to generate as much pressure. Maintaining this pressure is crucial for proper pulmonary function and efficient gas exchange.

Understanding these values helps in assessing right ventricular function and diagnosing conditions such as pulmonary hypertension or right heart failure. By interpreting right ventricular pressures accurately, healthcare professionals can better evaluate cardiovascular health and potential interventions needed.
