During dynamic investigation of a patient the increase of central venous pressure is combined with the decrease of arterial pressure. What process is proved by such combination?

Answer options

1. Depositing of blood in venous channel
2. Increase of bleeding speed
3. Shunting
4. Developing of cardiac insufficiency
5. Presence of hypervolemia

Explanation

Cardiac insufficiency, more commonly called heart failure, is when the heart muscles pump function is reduced. This leads to the heart being unable to produce the power to pump the required amount of blood throughout the body. This results in the decrease of arterial pressure with the compensatory mechanism of increase central venous return.
