Central venous pressure is an important determinant of venous return and thereby mean arterial pressure. Describe four factors that can alter central venous pressure.
Homework Answers
The four factors are-
1. Cardiac output- There is inverse relation, reduced cardiac output increased is the Venous pressure.
2. Contraction of limb & abdomen Muscle - This increases the VP.
3. Blood volume - there is direct relation, more the blood volume, more will be the VP.
4. Expiration - If the air is breathed out forcefully, VP tends to increase.
