'''Cardiopulmonary bypass''' ('''CPB''') or '''heart-lung machine''', also called '''the pump''' or '''CPB pump''', is a machine that temporarily takes over the function of the [[heart]] and [[lung]]s during [[open-heart surgery]] by maintaining the circulation of blood and oxygen throughout the body.<ref name="Raja.92">{{cite book |title=Cardiac Surgery: A Complete Guide |vauthors=Stefanou D, Dimarakis I |date=2020 |publisher=Springer |isbn=978-3-030-24176-6 |veditors=Raja SG |pages=93–99 |chapter=9.

CPB is operated by a [[perfusionist]]. The machine mechanically circulates and oxygenates blood throughout the patient's body while bypassing the heart and lungs allowing the surgeon to work in a bloodless surgical field.
