Cardiopulmonary bypass is a standard procedure frequently employed in various heart surgeries. It involves redirecting the circulation of blood away from the heart and lungs temporarily. During this process, blood is diverted from the natural path it would take through the heart and lungs and instead directed into a specialized machine located outside the body known as a cardiopulmonary bypass machine or heart-lung machine. This machine assumes the vital functions typically performed by the heart and lungs, such as oxygenating the blood, eliminating carbon dioxide, and then reintroducing the purified blood back into the body.
Cardiopulmonary bypass may be required for individuals undergoing the following surgeries:
Cardiopulmonary bypass is a procedure frequently used to support CABG. Healthcare providers often perform these procedures simultaneously. Cardiopulmonary bypass establishes an alternate route for blood circulation, diverting it away from your heart and lungs. This aids your surgeon in performing CABG with greater ease and safety.
Discuss the potential risks associated with cardiopulmonary bypass with your healthcare provider, and ensure you understand how your surgical team plans to address them. Generally, the duration of time spent on the bypass machine can impact the likelihood of complications. Additionally, your pre-surgery health status plays a role in determining your individual risk profile.
The following risk includes:
The heart-lung machine operates by establishing an extracorporeal circulatory route to oxygenate the blood. This process involves directing blood from the superior and inferior vena cava into tubing connected to a reservoir within the machine, where oxygenation takes place. The oxygenated blood is subsequently returned to the patient’s circulatory system via a tube linked to the aorta, the typical point of re-entry for oxygenated blood into the body after traversing the heart and lungs. This process is carefully supervised by a specialized surgical team comprising a surgeon, an anesthesiologist, and a perfusionist—a medical professional with specialized training in the supervision of cardiopulmonary bypass procedures.
During your surgical procedure, your healthcare team connects you to a heart-lung machine and closely monitors your condition. The process of conducting cardiopulmonary bypass involves several critical steps:
Once you are successfully disconnected from the heart-lung machine, your medical team continues to monitor your vital signs before transferring you to the intensive care unit (ICU) for post-surgery recovery.
Following surgery, the patient is gradually taken off cardiopulmonary bypass by the medical team. The heart and lungs are restarted first. Afterward, the machine is gradually turned off to allow the heart and lungs to take over completely.
Before the patient is moved to the intensive care unit (ICU) for recovery, the medical staff continues to check the patient’s levels while they are off the pump.
Consulting with your healthcare provider is the most advisable course of action for inquiries regarding your recovery, as it can be influenced by several factors including the specific procedure performed, your medical background, age, and the duration of time spent on the pump. Engaging in a conversation with your healthcare provider will provide you with a comprehensive understanding of what to anticipate following your surgical procedure.
Your healthcare provider will inform you about the necessary follow-up appointments. It’s essential to attend all scheduled appointments and adhere to your provider’s guidance diligently. Don’t hesitate to contact your provider whenever you have inquiries or concerns regarding your recovery.
