What is the normal range for central venous pressure (CVP)?

The normal range for central venous pressure (CVP) is indeed 5-10 mmHg. CVP is a critical measurement that reflects the pressure in the thoracic vena cava, near the right atrium of the heart, and provides important information about a patient's volume status and cardiac function.

A range of 5-10 mmHg indicates adequate venous return to the heart, which is essential for maintaining cardiac output and overall circulatory health. Values below this range may suggest hypovolemia, indicating that the body is not distributing blood volume effectively, while values above this range could indicate fluid overload or right-sided heart failure. Hence, understanding the normal CVP range is vital in the assessment and management of patients, particularly those with conditions such as heart failure, sepsis, or those undergoing major surgeries.

Incorrect options represent values outside the established normal range for CVP. Values below 5 mmHg may not provide sufficient venous return, while those above 10 mmHg could signal potential complications that need to be addressed. This contextual understanding helps in the clinical application of CVP monitoring to ensure optimal patient care.
