The full form of CVP is Central Venus Pressure. Fluid treatment is frequently guided by the CVP parameter. In the absence of tricuspid stenosis, CVP, also known as mean vena cava or right atrial pressure, equals right ventricular end-diastolic pressure. The CVP measures both the volume of blood returning to the heart and the heart’s capacity to pump blood back into the arterial system. Right atrial pressure (RAP) and CVP are frequently close approximations.

Central Venous Pressure in ICU
The most popular technique for directing fluid resuscitation in critically unwell patients is CVP. The right atrium, superior or inferior vena cava, or central venous catheter (CVC) are the most common locations for this procedure.
CVP has been and is currently often utilized as a substitute for preload, and variations in CVP in response to intravenous fluid infusions have been used to forecast volume responsiveness. The central venous catheter of the patient can be connected to a particular infusion device to measure CVP.

What Causes an Elevated CVP?
In critical care settings, elevated right atrial pressure or central venous pressure (CVP) is a common occurrence that can be brought on by a number of different conditions, including congestive heart failure syndrome, constrictive pericardial disease, tension pneumothorax, and the resuscitation/evacuation stages of septic shock.
