What are cardiac perfusionist

Perfusionists are allied health professionals who are in charge of the operation, maintenance and record of the CPB machine in not only heart surgeries, but also any other medical intervention that might require a temporary artificial support for the patient’s circulatory or respiratory function.

Perfusion is the passage of blood, or other fluid circulating through the blood vessels or other natural channels in the human’s organ. So sometimes, when the surgeons are operating on the heart, they would need a substitute to do the heart’s normal function. Together, they work in collaboration with a surgical team, including cardiothoracic surgeons, anesthesiologists, cardiac care nurses and other operating room technicians.

A perfusionist duties

Perfusionists are not physicians nor nurses, but they perform a vital role during heart surgery. Their role before and during a surgery might include:

  • Reread and study the patient’s medical history and notes
  • Operating the extracorporeal circulation equipment, such as the artificial heart, intra-aortic balloon pump and many more ventricular-assist devices
  • Regulating patient’s blood flows and temperature
  • Monitor vital signs to ensure safe physiologic functions and making adjustments as needed
  • Administering chemicals and blood products for patients to remain stable during surgery
  • Maintain and constantly conduct quality check on the equipments, including routine pre-surgical evaluations

Perfusionists’ main focus are open heart surgeries, however, if needed they are able to assist in other forms of heart surgeries like congenital heart defect, heart disease treatment and sometimes even emergency cases.

How to be a perfusionist

To start off, becoming a perfusionist will require a strong background in biology, mathematics and other sciences during highschool period. After that, they will go on to a higher study and earn a bachelor degree in the related fields then attend cardiovascular perfusionist school and obtain certification. When certified, they are considered board-eligible, meaning that while they are earning licensing, they are employable in the meantime. Types of certification they might be required to have include a degree from an Accredited Perfusion Technology Program or approved program of Extracorporeal Technology and depending on the location they will need to sit an exam to become a certified clinical perfusionist (CCP).


Cardiac perfusionist is an extremely beneficial career if you want to work in the medical field yet don’t really want to be a physician. This position will place you in the front of one of the most exciting fields or surgical practices and you are able to interact directly with a cardiologist, collaborating as a team.
