Blood Volume Expansion

What is Blood Volume Expansion?

Blood volume expansion (BVE) is a medical procedure in which fluid or a saline solution is intravenously infused into a patient to increase their circulating blood volume. The purpose of BVE is to increase blood pressure, treat hypovolemic shock, and support cardiac output. BVE may also provide symptomatic relief for patients with hypotensive states such as congestive heart failure, septic shock, and acute blood loss.

How Does Blood Volume Expansion Work?

The procedure is typically performed by a healthcare professional, and the solution used is usually a balanced crystalloid solution. The specific type of fluid and the amount used will be determined by the patient's current health and blood volume. During the procedure, the fluid is slowly infused over 10–20 minutes, and is done so until the patient's blood volume is increased to a sufficient level.

Benefits of Blood Volume Expansion

Blood volume expansion is a useful tool in treating a variety of medical conditions that can result in hypotension. The infusion of fluid helps to improve oxygenation of vital organs, enhance circulation, and increase organ perfusion. Here are some of the primary benefis of BVE:

  • Increases blood pressure
  • Enhances blood circulation
  • Improves oxygenation of vital organs
  • Enhances organ perfusion
  • Relieves hypotensive states
  • Decreases the risk of cardiovascular problems

Risks of Blood Volume Expansion

Blood volume expansion is generally a safe procedure, however there are some potential risks associated with it. These risks include infection, pulmonary edema, thrombophlebitis, and volume overload. Additionally, hyponatremia may occur if too much of a saline solution is infused.

Overall, blood volume expansion is a valuable and successful treatment for many people who suffer from hypotension. However, it is important to note that the procedure should only be carried out by a qualified medical professional, and that the risks and benefits should be discussed before proceeding.
