Introduction
The heart lung machine is a vital tool in modern heart surgery. It takes over the job of the heart and lungs during certain operations. Because of this, doctors can safely repair or replace heart parts. Many lives have been saved thanks to this machine. In this blog, you will learn how the heart lung machine works, when it is used, and how doctors keep patients safe.
How the Heart Lung Machine Works
During surgery, the heart lung machine keeps blood moving and adds oxygen to it. First, doctors connect tubes from the patient to the machine. Next, the machine pumps blood out of the body. Then, it removes carbon dioxide and adds oxygen. After that, the machine sends the clean blood back to the body. This process is called “cardiopulmonary bypass.” Because the machine does the work of the heart and lungs, surgeons can stop the heart to fix it.
When Is a Heart Lung Machine Used?
Doctors use the heart lung machine in many heart surgeries. For example, it is needed when the heart must be stopped. Some common procedures include:
Sometimes, the machine is also used in emergency situations. In rare cases, it helps during lung surgery or other complex operations.
Benefits and Risks
There are many benefits to using a heart lung machine. For instance, it allows doctors to perform life-saving surgeries. It also gives surgeons more time to work safely. However, there are some risks. Because the machine takes over for the heart and lungs, problems can happen. Some possible risks include:
Most people do very well after surgery. Still, doctors always weigh the benefits and risks before using the machine.
Safety Measures and Monitoring
Doctors and nurses use many safety steps with the heart lung machine. First, a trained specialist called a perfusionist runs the machine. This expert checks blood flow, oxygen, and pressure at all times. In addition, doctors use alarms and backup systems. Because of these steps, the risk of problems is very low. Hospitals also follow strict rules to keep patients safe. According to the American Heart Association, these safety measures help prevent most issues.
What to Expect During Surgery
Before surgery, doctors explain the process and answer questions. During the operation, you will be asleep under anesthesia. While you sleep, the heart lung machine takes over. Surgeons then stop your heart and fix the problem. After the repair, your heart is restarted. The machine is slowly turned off as your heart and lungs take over again. Nurses and doctors watch you closely the whole time.
Recovery and Aftercare
After surgery, you will wake up in a special care unit. Nurses will check your heart, breathing, and blood pressure often. Because your body needs time to heal, you may feel tired or weak at first. Most people stay in the hospital for a few days. Doctors will give you advice on caring for yourself at home. For example, you may need to avoid heavy lifting or driving for a while. Follow all instructions to help your recovery go smoothly.
