In the U.S., once death is declared in a hospital (after a car accident or other cause), the organ donation process follows strict medical and legal steps:


1. Death Declaration

  • Doctor pronounces death based on:

    • Cardiac death (heart and breathing stop, no return despite resuscitation)
      or

    • Brain death (irreversible cessation of all brain function), confirmed by accepted medical standards and usually two physicians.

  • This is done before organ donation discussions.


2. Notify Organ Procurement Organization (OPO)

  • Federal law (U.S.): Hospitals must notify their OPO whenever a patient meets clinical triggers for potential donation.

  • The OPO:

    • Reviews eligibility.

    • Checks donor registry.

    • Assigns a coordinator.


3. Family Authorization or Registry Check

  • If the patient is a registered donor → OPO proceeds with consent on file.

  • If not registered → OPO asks the next of kin for consent.

  • Hospital staff do NOT ask for organs; only trained OPO coordinators do this.


4. Organ Preservation and Matching

  • If death was from brain death:

    • Life support is maintained temporarily to keep organs viable.

  • OPO enters donor data into the UNOS system (United Network for Organ Sharing) to match recipients.

  • Blood type, tissue type, urgency, and location determine allocation.


5. Organ Recovery Surgery

  • Done in an operating room, by transplant surgeons.

  • After recovery, the body is prepared for funeral arrangements per family wishes.


6. Timeline

  • Must act quickly:

    • Hearts/lungs: 4–6 hours after removal.

    • Kidneys/liver: 12–36 hours.
