The brain can’t survive long without oxygen: unconsciousness happens within seconds, brain damage starts after about 1–2 minutes, and after 3–5 minutes the injury is usually severe and permanent. Beyond 5–6 minutes, survival without major deficits is rare, and at around 10 minutes brain death is likely. Fifteen minutes without oxygen almost always means death, not just coma, unless special conditions like induced hypothermia are present.
