A cardiovascular perfusionist, clinical perfusionist or perfusiologist, and occasionally a cardiopulmonary bypass doctor^[1][2] or clinical perfusion scientist,^[3] is a healthcare professional who operates the cardiopulmonary bypass machine (heart–lung machine) during cardiac surgery and other surgeries that require cardiopulmonary bypass to manage the patient's physiological status.^[4] As a member of the cardiovascular surgical team, the perfusionist also known as the clinical perfusionist helps maintain blood flow to the body's tissues as well as regulate levels of oxygen and carbon dioxide in the blood, using a heart–lung machine.^[4]
