What happens to the lungs during bypass surgery?

Reductions in lung volumes and oxygenation are common during the initial period after open-heart surgery. The effects of the median sternotomy, hypothermia for myocardial protection, dissection of the internal mammary artery, and the use of cardiopulmonary bypass negatively influence lung function [1–4].

What are the risks of heart bypass surgery?

While the heart bypass machine has improved greatly in recent years, there are still risks associated with the use of the pump. Bleeding: Risk is increased due to the blood-thinning medications used during pumping. Blood Clots. Stroke: Cardiopulmonary bypass increases the risk of clots that may travel to the brain.

Which is the most common type of heart bypass surgery?

Bypass surgery is also known as coronary artery bypass grafting (CABG). It’s the most common type of open-heart surgery in the U.S. A surgeon removes a blood vessel, called a graft, from another part of your body, like your chest, leg, or arm.

What causes chest pain after quadruple bypass surgery?

In some people, the coronary arteries become blocked—a condition known as coronary artery disease where plaque builds up in the blood vessel. 4  If the blockage in the coronary artery is severe, it can prevent blood flow to the part of the heart that is fed by the diseased blood vessel, causing chest pain, also known as angina. 5
