Venous Reservoir

A venous reservoir is a specialized component of a heart-lung machine used during surgeries. It acts like a storage tank that collects blood returning from the body via veins, allowing the surgical team to monitor and manage blood volume. This reservoir helps maintain proper blood flow and pressure, ensuring that oxygenated blood can be safely returned to the patient’s circulatory system after it’s been oxygenated outside the body. Essentially, it ensures a steady, controlled flow of blood during complex medical procedures, supporting the patient's stability throughout surgery.
