Question
1. Central venous pressure describes pressure in:
- a. Inferior vena cava near right atrium
- b. Superior vena cava right atrium
- c. Left atrium
- d. Abdominal aorta
Solution
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 into the arterial system.
So, the answer to your question is:
a. Inferior vena cava near right atrium b. Superior vena cava near right atrium
Both the superior and inferior vena cavae are involved in central venous pressure as they both return blood to the right atrium of the heart.
