Final answer:
The normal values for central venous pressure (CVP) range from 0-5 mmHg, indicating adequate blood volume and cardiac output. Higher values may suggest fluid overload or heart failure, while lower values may indicate dehydration or hypovolemia.
Step-by-step explanation:
The normal values for central venous pressure (CVP) range from 0-5 mmHg. This pressure is measured in millimeters of mercury (mm Hg) and represents the pressure in the large veins near the heart. It is an important indicator of blood volume and how well the heart is functioning.
For example, a CVP of 0-5 mmHg is considered normal and indicates adequate blood volume and cardiac output. Higher values may suggest fluid overload or heart failure, while lower values may indicate dehydration or hypovolemia.
Therefore, the correct answer is a. 0-5 mmHg.
