Why is it necessary for a patient to be connected to heart-lung machine during double lung transplants?

Poor lung function. Double lung transplants when done "en block" obviously need the heart lung machine. When done asynchronously require bilateral anterior thoracotomies, and one lung anesthesia. If lung function too poor to allow one lung anesthesia then en block is the only option. The transplant surgeon is the only one that can judge which technique is appropiate to his patient.

Oxygenation. The lungs need to be disconnected from the heart and the new once attached. This cannot happen with the heart beating; blood circulation needs to be stopped in the heart and lungs. During this time the machine oxygenates and pumps the blood to the rest of the body. Read more...

Dot light moves across my field vision and goes (many times)after was on Heart-Lung machine 3 yrs ago for heart valve repair now twice a yr. Ideas?

Whether or not. there's a connection between your mitral valve repair 3 years ago and your symptoms now, you should see an eye doctor. You can start with a licensed optometrist who can then refer you to a ophthalmologist if necessary.
