Central venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system.
The doctor can then ask the patient to relax while the back of the examination table is raised to a 30-45˚ angle. From this position, the jugular venous pressure (JVP) can be estimated. Because the right internal jugular vein flows directly into the superior vena cava and then the right atrium, it is a good estimate of central venous pressure.
Such situations include, but are not limited to, the need for long-term venous access (for weeks or months, not days), [1] administering of medications that can damage smaller veins (e.g. chemotherapy), measuring central venous pressure, obtaining certain blood tests (specifically central venous oxygen saturation), or performing dialysis.
Venous pressure is the vascular pressure in a vein or in the atria of the heart. It is much lower than arterial pressure, with common values of 5 mmHg in the right atrium and 8 mmHg in the left atrium. Variants of venous pressure include: Central venous pressure, which is a good approximation of right atrial pressure, [37] which is a major ...
These include single pressure, dual pressure, and multi-parameter (i.e. pressure / temperature). The monitors can be used for measurement and follow-up of arterial, central venous, pulmonary arterial, left atrial, right atrial, femoral arterial, umbilical venous, umbilical arterial, and intracranial pressures.
Central lines are used to administer medication or fluids that are unable to be taken by mouth or would harm a smaller peripheral vein, obtain blood tests (specifically the "central venous oxygen saturation"), administer fluid or blood products for large volume resuscitation, and measure central venous pressure.
The horizontal axis of Guyton diagram represents right atrial pressure or central venous pressure, and the vertical axis represents cardiac output or venous return. The red curve sloping upward to the right is the cardiac output curve, and the blue curve sloping downward to the right is the venous return curve. A steady state is formed at the ...
MAP = mean arterial pressure (mmHg) CVP = central venous pressure (mmHg) CO = cardiac output (L/min) [27] To get this in Wood units the answer is multiplied by 80. Normal systemic vascular resistance is between 900 and 1440 dynes/sec/cm−5. [28]
