Incredible. I wonder if they can make progress on survivability of regular drowning.

Unlikely. The issue is cold and the speed of the cold. Children have a higher surface-to-mass ratio along with less subcutaneous fat which allows them to cool quickly. The article quotes the breakpoint:

  If water temperature is >6 °C (43 °F), survival is unlikely for submersion >30 minutes.
And even still, it isn't like the child came out unscathed.

I was rewatching The Abyss for the first time since 1989 and wondered just what is the process for reviving an asystole heart[^1].

[^1]: It was only relatively recently that I learned you can't shock an asystole heart. e.g. https://medicalsciences.stackexchange.com/questions/5874/can...

CPR and a boatload of epinephrine, it seems.

That passage bears quoting at length, it's where I really teared up:

> At initiation of ECMO, the boy's rhythm was asystole. The boy was rewarmed with an ECMO heat exchanger-patient gradient ≤10 °C. [...] As the patient's temperature approached 22 °C (72 °F), low-frequency and low-amplitude sinusoidal electrical deflections were noted on his electrocardiogram. As the patient continued to rewarm, these phasic electrical deflections slowly increased in frequency and amplitude. At approximately 28 °C (82 °F), sinusoidal deflections organized into more classic cardiac electrical activity reminiscent of sinus bradycardia with a wide complex. Amiodarone, calcium gluconate, magnesium sulfate, bolus epinephrine, and epinephrine and norepinephrine infusions were administered. After further rewarming, sinus bradycardia developed and ultimately progressed to normal sinus rhythm...

"Survival" here being, of course, not a black-and-white thing:

    > Outcome and Follow-Up
    > On day 59, the boy was discharged to inpatient neurorehabilitation. At 6-month follow-up, he was giving short commands, standing without support, riding a tricycle, eating soft foods, and relearning simple tasks. Peripheral neuromuscular weakness continued to improve.
