OperationIt carries blood from the upper-right chamber of the heart (the right atrium) to a special reservoir called an oxygenator. Inside the oxygenator, oxygen bubbles up through the blood and enters the red blood cells. This causes the blood to turn from dark (oxygen-poor) to bright red (oxygen-rich). Then, a filter removes the air bubbles from the oxygen-rich blood, and the blood travels through a plastic tube to the body’s main blood conduit (the aorta). From the aorta, the blood moves throughout the rest of the body.
Common Problems• In the damaged parts and sensors.
• Centrifugal motors may make noises and squeaks.
• The roller pumps require sufficient tubing retention force to prevent migration during use.
