A beating heart cadaver is a body that is pronounced dead in all medical and legal definitions, connected to a medical ventilator, and retains cardio-pulmonary functions. This keeps the organs of the body, including the heart, functioning and alive.[1] As a result, the period of time in which the organs may be used for transplantation is extended. The heart contains pacemaker cells that will cause it to continue beating even when a patient is brain-dead. Other organs in the body do not have this capability and need the brain to be functioning to send signals to the organs to carry out their functions. A beating heart cadaver requires a ventilator to provide oxygen to its blood, but the heart will continue to beat on its own even in the absence of brain activity.[2] This allows organs to be preserved for a longer period of time in the case of a transplant or donation. A small number of cases in recent years indicate that it can also be implemented for a brain-dead pregnant woman to reach the full term of her pregnancy.[2] There is an advantage to beating heart cadaver organ donation because doctors are able to see the vitals of the organs and tell if they are stable and functioning before transplanting to an ailing patient.[3]
This is not possible in a donation from someone pronounced dead.[citation needed]
