Perfusionists work primarily in hospital operating rooms, where they run the heart-lung machine during open-heart surgery and other procedures that require temporarily taking over a patient’s circulation. About 75% of cardiovascular technologists and technicians work in state, local, and private hospitals. But the operating room isn’t the only option. Perfusionists also work in pediatric heart centers, intensive care units, transplant programs, medical device companies, and universities.
Hospital Operating Rooms
The core workplace for most perfusionists is the cardiac surgery operating room. When a surgeon needs to stop or open the heart, someone has to keep blood flowing through the patient’s body. That’s the perfusionist. They operate the heart-lung machine, monitor vital signs, and manage blood flow, body temperature, and oxygen levels throughout the procedure.
Perfusionists work alongside cardiac surgeons, anesthesiologists, physician assistants, surgical technologists, and nurses. The environment is a standard hospital OR or a large surgical center. Most cardiac surgery programs are housed in mid-to-large hospitals or academic medical centers, so those tend to be where the jobs concentrate. Smaller community hospitals that don’t perform open-heart surgery generally don’t employ perfusionists on staff.
Pediatric and Congenital Heart Centers
Children’s hospitals with cardiac surgery programs hire perfusionists specifically trained in pediatric cases. The work is more specialized because the equipment, blood volumes, and techniques differ significantly from adult surgery. A pediatric perfusionist at a busy center might support around 150 open-heart procedures a year, including heart transplants and ventricular assist device implantation. These roles typically require at least three years of pediatric-specific experience, making them a career step beyond entry-level positions.
Major children’s hospitals also serve as clinical training sites for perfusion students, so the role can blend hands-on patient care with teaching responsibilities.
ICU and ECMO Transport Teams
Perfusionists increasingly work outside the OR in critical care settings, particularly with ECMO (extracorporeal membrane oxygenation). ECMO is essentially a portable version of the heart-lung machine used on patients whose heart or lungs are failing, sometimes for days or weeks at a time. This work happens in intensive care units rather than operating rooms.
Some perfusionists are part of mobile ECMO transport teams that move critically ill patients between hospitals. A typical transport team includes ECMO physicians, a nurse, a perfusionist, a respiratory therapist, and a critical care paramedic. The perfusionist’s job during transport is to maintain the ECMO circuit, troubleshoot equipment problems, and manage the patient’s circulation during what can be a high-stakes road or air transfer. This is one of the more physically varied settings in the profession, since you’re working in ambulances, helicopters, or fixed-wing aircraft rather than a controlled OR environment.
Transplant and Specialty Surgery Programs
Beyond traditional cardiac surgery, perfusionists support organ transplant programs and certain cancer surgeries. In liver transplantation, for example, machine perfusion devices keep donor organs viable outside the body before implantation. Perfusionists may also assist with procedures like HIPEC (heated chemotherapy delivered directly into the abdomen), where their expertise in managing fluid circuits and temperatures translates directly.
These roles exist in large academic medical centers and specialty surgical hospitals that handle complex cases. They represent a smaller slice of total perfusionist employment but offer variety for those looking to move beyond standard cardiac cases.
Hospital-Employed vs. Private Perfusion Groups
How a perfusionist is hired matters as much as where they work. Some perfusionists are direct employees of a hospital, working exclusively at that facility. Others work for private perfusion service companies that contract with one or more hospitals to provide coverage. Both models put you in the same operating room doing the same work, but the employment structure affects your schedule, benefits, and how many different surgical teams you interact with.
The broader trend in healthcare has been a shift toward hospital employment over private practice, driven by rising operating costs and the desire for schedule stability. Younger professionals coming out of training increasingly choose the employed model. That said, private groups remain common in perfusion, particularly in regions where multiple hospitals need coverage but none perform enough cases to justify a full-time in-house team.
Travel Perfusion
Travel perfusionists take temporary assignments at hospitals across different cities and states, filling staffing gaps, covering surgical surges, or stepping in during leaves of absence. This is similar to travel nursing but in a much smaller, more specialized field. Assignments typically last weeks to months, and you work with a different OR team at each facility.
Travel positions tend to pay more than permanent roles to compensate for the lack of stability and the constant adjustment to new teams and hospital systems. Staffing agencies that specialize in perfusion handle placement and logistics. For perfusionists who want geographic variety or higher short-term earnings, travel work is a well-established path.
Medical Device Companies
Perfusionists with clinical experience are recruited by companies that manufacture heart-lung machines, oxygenators, ECMO circuits, and related equipment. These industry roles include clinical specialist positions (where you train hospital staff on new products and support cases in the OR), clinical research, and product development. Some of these positions are remote, while others involve extensive travel to hospital sites. The American Society of Extracorporeal Technology regularly lists industry roles like clinical research engineer positions alongside traditional hospital jobs.
Universities and Training Programs
Perfusion education depends heavily on experienced clinicians who teach the next generation. University-based perfusion programs, like the one at The Ohio State University’s College of Medicine, employ perfusionists as faculty and clinical instructors. In the clinical practicum model, working perfusionists at affiliate hospitals serve as preceptors, supervising students during actual surgeries. One program tracked 430 student-preceptor relationships across 24 affiliate institutions with 134 clinical instructors, illustrating how widely the teaching role is distributed.
Academic positions combine classroom instruction, simulation lab work, and oversight of students in the OR. They suit experienced perfusionists looking for a role that balances clinical work with education and quality improvement projects.
Day-to-Day Work Environment
Regardless of setting, perfusion work revolves around a few constants. You spend most of your time in temperature-controlled, brightly lit operating rooms or ICUs. The work is physically stationary compared to nursing (you’re stationed at the perfusion machine) but mentally intense, since you’re continuously monitoring and adjusting the patient’s circulation in real time.
On-call requirements are common across nearly all settings. Cardiac emergencies don’t follow a schedule, so most perfusionists carry a pager or phone for after-hours cases. At high-volume centers, teams rotate call coverage. At smaller programs with fewer perfusionists, call frequency can be significantly higher. Outpatient care centers and physician offices employ a small percentage of cardiovascular technologists (about 2% and 13%, respectively), though these settings are more common for other cardiovascular specialties than for perfusionists specifically.
