“…it can be considered acceptable to start measures guided to preserve the organs with the possibility of a posterior transplant, while detecting relatives who can transmit the donation will of the death person…”
“ The procurement of organs from NHBD Type III of Maastricht is excluded from the consensus document until further regulations due to ethical reasons.”

Donors after Cardiac Death. Historical background in Catalonia
I. Extrahospitalary CRA that, after a period of >30 minutes of advanced CPR maneuvers, it’s irreversible, and the ALS is maintained for transporting to the specific reference center (with independence of the geographic place) only with the aim of obtaining the organ and tissue donation.
II. CRA inside or outside the hospital. The transport to the hospital is done with a therapeutic aim and after advanced CPR maneuvers, reanimation is not achieved and the patient is declared death.
III. Awaiting cardiac arrest.
IV. Cardiac arrest while brain death
