The Maquet HL-20 heart lung machine is a medical device used in cardiac surgery to temporarily take over the functions of the heart and lungs. It is also known as a cardiopulmonary bypass machine.
During cardiac surgery, the patient’s heart is stopped so that the surgeon can operate on it. The HL-20 machine is used to circulate blood and oxygen to the rest of the body while the heart is stopped. The machine pumps blood out of the patient’s body, oxygenates it, removes carbon dioxide, and then pumps it back into the patient’s body.
The HL-20 machine has several components, including a pump, an oxygenator, a heat exchanger, and a filter. The pump is responsible for moving blood through the machine, while the oxygenator adds oxygen to the blood and removes carbon dioxide. The heat exchanger helps to regulate the temperature of the blood, and the filter removes any particles or debris from the blood.
The HL-20 machine is designed to be highly reliable and to provide precise control over blood flow, pressure, and oxygenation. It is also easy to use, with an intuitive user interface and a range of safety features to prevent errors or malfunctions.
Overall, the Maquet HL-20 heart lung machine is an essential tool in cardiac surgery, allowing surgeons to perform complex procedures with confidence while ensuring that patients receive the oxygen and blood flow they need to survive.
