  1. Cardiopulmonary Bypass Machine By: Kim Stephens

  2. What is a cardiopulmonary bypass machine? Also called a heart-lung machine or a pump Does the work of the heart and lungs when the heart is stopped pumps blood through the body oxygenates the blood while pumping, replacing the function of the lungs

  3. Why is it used? 2 Main Reasons: 1. Most commonly used to stop the heart during surgery 2. A heart failure patient can sometimes be placed on the pump while waiting for a heart transplant

  4. How does the CBM work? Insert tubes into the vena cava of the heart Blood then travels to a chamber in the CBM that collects and stores blood from the body Blood travels into the CBM’s pump which pushed blood through the machine

  5. How it works cont. Blood flows from the pump to the heat exchanger Blood then enters the oxygenator The cooled, oxygenated blood then goes through a filter Once the blood is filtered it goes through a second set of plastic tubes which is attached to a large artery, like the aorta or femoral artery back to the body

  6. Advantages/Disadvantages

  7. Future • Portable machines • Miniature Heart-Lung Machine • Only testing at this point on small animals • Positive results • Further testing will show the advantages of miniHLM versus the HLM
