Artificial circulation, also known as an extracorporeal circulation system, is a form of medical intervention which utilizes a mechanical pump, artificial organ, or other device to artificially circulate blood or other substances around a living body. The most common use of artificial circulation is in cardiac bypass surgery, where a machine takes over the role of the heart to pump oxygen-enriched blood through the body.

In cardiopulmonary bypass, the artificial circulation unit acts as a bridge between the heart and lungs, allowing for a safe and consistent flow of oxygenated blood to the rest of the body during open heart surgery. The usual setup consists of a cardiopulmonary bypass pump, oxygenator, and tubing. The patient’s blood is taken from the right atrium of the heart, routed through the oxygenator, and then sent back to the patient’s body via the tubing.

Another common application of artificial circulation is extracorporeal membrane oxygenation (ECMO), a form of life support. The ECMO system consists of a pump, an oxygenator, and a membrane that mimics the lungs, allowing oxygen to be absorbed into the patient’s bloodstream. The system can provide long-term mechanical ventilation, respiratory support, and circulatory support for people who are unable to breathe or maintain a stable heart rate.

In addition, artificial circulation is often used to treat patients with severe sepsis. The artificial circulation unit can be used to supplement or replace the normal circulation of the patient’s own heart and lungs. In some cases, the device is used to help move oxygenated blood to parts of the body that are not receiving enough oxygen from the natural circulation system.

The use of artificial circulation systems is an important part of modern medical care, providing an artificial means of maintaining the flow of oxygen and other vital substances to the body during times of medical need. By providing a safe and consistent flow of oxygenated blood, these systems allow for successful operations and treatments that would not otherwise be possible.
