Central venous pressures refer to the measurement of pressure in the large veins in proximity to the heart. Synonyms for this term include CVP, central venous pressure, and intracardiac pressure. CVP reflects the pressure within the right atrium and is an important indicator for assessing cardiac function and volume status. Additionally, synonyms may extend to abbreviations such as RAP (right atrial pressure) or RVP (right ventricular pressure) when referring to pressure in specific heart chambers. Monitoring central venous pressures is crucial in managing patients with cardiovascular diseases, as it provides valuable information about the heart's ability to pump blood effectively.
