People can sometimes recover after their heart has stopped for 30 minutes in cases such as near-drowning in very cold water.
Is it true that people can sometimes recover after their heart has stopped for 30 minutes in cases such as near-drowning in very cold water?
Yes. Severe accidental hypothermia, such as that caused by near-drowning in freezing water, lowers metabolic demand and can enable full neurological recovery even after prolonged cardiac arrest.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The claim is specific and empirically testable, passing Step 0. The provided literature includes case reports and clinical reviews showing that individuals, particularly children, can sometimes make full recoveries following cardiac arrest caused by severe hypothermia from cold water submersion, even after prolonged periods. Therefore, the claim is supported by the evidence.
