Perfusionists are vital members of the cardiovascular surgical team. A perfusionist assists the team during various types of cardiac surgical procedures. His or her primary responsibility is to operate a heart/lung machine that artificially replaces a patient’s heart or lung functions during surgery.
Perfusionists are responsible for:
- Setting up, operating and maintaining complex perfusion equipment;
- Monitoring circulation;
- Regulating the levels of oxygen and carbon dioxide in the blood;
- Regulating the body temperature;
- Measuring laboratory values (i.e., arterial/venous blood gases, clotting times); and
- Administering medication and blood products through the bypass circuit (under the supervision and direction of the anesthesiologist and surgeon)
Additional job responsibilities may include various administrative duties, such as purchasing supplies and equipment, managing the department they work in, and hiring support technicians when necessary.
Perfusionists should be people-oriented as they will be working with patients as well as working directly with the nursing staff, anesthesiologists, cardiac and pulmonary surgeons, surgical technicians and other allied health professionals.
A perfusionist is required to:
- Concentrate for long periods of time while keeping a record of the patient’s vital signs through the entirety of surgery;
- Notify the surgeon immediately of any changes, and be prepared to respond quickly to the physician’s requests;
- Be detail-oriented, follow instructions thoroughly, and respond well to emergency situations; and
- Work well under pressure, be able to work well independently, and assist with post-operative support concerning the patient
