Frequently asked questions FAQs about it
1. What is perfusion science, and why is it important in cardiac surgery?
Answer: Perfusion science focuses on the management of blood flow during surgery, especially when the heart and lungs need to be temporarily bypassed. It’s critical in cardiac surgery as it ensures the body receives adequate oxygenation and nutrient delivery while the heart undergoes repair or other procedures. Perfusionists manage machines like CPB and ECMO to maintain these vital functions.
2. How does ECMO work, and when is it used in cardiac care?
Answer: ECMO (Extracorporeal Membrane Oxygenation) is a life-support system that temporarily takes over the function of the heart and lungs. It’s used for patients experiencing severe cardiac or respiratory failure. ECMO circulates blood through an external oxygenator and pump, allowing the heart and lungs to rest and recover. It’s commonly used in patients awaiting heart transplant or during severe complications like cardiac arrest.
3. What are the advantages of using cell saver technology in cardiac surgery?
Answer: Cell saver technology allows for the recovery of a patient’s own blood lost during surgery. This is then filtered and returned to the body. The advantages include reducing the need for donor blood transfusions, minimizing risks of transfusion reactions, and lowering the chances of infection or immune response, making recovery safer and faster.
4. How does IABP (Intra-Aortic Balloon Pump) support heart function during surgery?
Answer: The IABP is a mechanical device that assists the heart by inflating and deflating a balloon inside the aorta during the cardiac cycle.
