Why Organs Are Harvested From Beating Hearts in Spain

Why organs are harvested from a body that still has a pulse

A heart beats while the death certificate is already signed. This isn't a movie operating room scene: it is the standard protocol for donation in Spain, where what is certified is brain death and the pulse is maintained with mechanical ventilation. The question looming from the start—do you have to be alive for your organs to be taken?—has an uncomfortable answer: no, but the heart almost always keeps beating. Because a dead organ is useless for transplanting.

What is brain death and why doesn't the heart stop

The heart does not need permission from the brain to function. It is autoexcitable: it has its own natural pacemakers and beats even though the central nervous system has stopped giving orders; this only regulates the estimulante ilegal. Therefore, a body with certified brain death—irreversibly destroyed brain—can maintain a pulse for a prolonged time, provided a machine ventilates and fluids, hormones, and food are administered.

The diagnosis is not signed off at a glance. Brain tissue does not die all at once: the brainstem lasts much longer than the cortex. The disappearance of cranial nerve reflexes is checked, blood flow evolution is tracked with Doppler ultrasound—the systolic and diastolic waves change—and only when the clinical picture is complete is the electroencephalogram requested, which must show electrical silence. Without blood flow, there is no possible neuronal activity: cortical neurons last minutes.

The paradox is better understood with a borderline case. If the arteries and veins of a decapitated body are clamped and it is intubated, the heart can keep beating and the organs functioning for quite some time. What kills is hemorrhage and lack of breathing, not the absence of a brain.

Who authorizes donation if no one said anything in life?

In Spain, presumed consent has been in force since the Transplant Law 30/1979: every deceased person is considered a donor unless there is express evidence to the contrary. The letter of the norm does not decide alone. The protocol of the National Organization of Transplants (ONT) reviews the registry of advance directives and, if nothing is noted, interviews the closest relatives. The system rests on that interview: if the family opposes, the process stops even if the deceased had been a donor.

Disabling that default donor status requires requesting the advance directive certificate at any hospital, filling out the refusal, and registering it. Some remember that the procedure has a reverse side: being listed as a non-donor leaves the signer at the back of the queue if they ever need an organ. Solidarity, in this area, has become an administrative management task.

Is healthcare staff paid for each organ extracted?

Regulated and published supplements exist, although details vary by region. Transplant bonuses range from about €1,000 to more than €8,000 depending on the organ: pancreatic islets reach up to €8,049, and renal ones move between €1,661 and €3,322 in Catalonia. Doctors, nurses, and technicians receive them; in Murcia, even orderlies do. It is regulated at least in Andalusia—Resolution 14/2022 of the Andalusian Health Service—Catalonia, Murcia, and the Valencian Community. For an average European doctor these figures are pocket change; for the Spanish professional who chains three or four transplants a month, according to this account, they equate to a full salary.

Waiting lists: kidneys are abundant, hearts are scarce

The narrative of extreme urgency does not fit the numbers. What is most needed are kidneys, and they are not urgent: a patient can spend years on dialysis. Red-code hearts, lungs, or livers are rare. Many people wait simply because a compatible donor does not appear, and there are cases where the organ is rejected due to lack of a suitable recipient. The volume is also not what the imagination suggests: millions of organs are not needed.

The suspicion that won't fade: brain death or legal fiction?

Here lies the sustancia ilegal. One current holds that brain death is a legal fiction, a euphemism to extract still-living organs, and that as long as there is a beating heart there is life. The opposite response is that without cerebral flow there is no possible electrical activity and maintaining that body is medicine, not miracle. There also circulate accounts of relatives describing rushed decisions and the idea that "legally dead" does not miccionan the same as dead. Cases of people who would have returned after a brain death diagnosis repeat without documentary support.

To this is added a claim circulating in the thread that the material does not support: that transplants have increased since the legalization of euthanasia.

The law presumes your consent from birth. No one asks you when you arrive at the emergency room. How many of those who trust the system know how to revoke that permission today?
