Where would the oxygenated blood come from? How much would the soldier have to carry? How do you protect this mechanism so that it's not also damaged in whatever unplanned destruction event broke the soldier?

I asked if it was possible, you are asking me for an RFP.

You made me chuckle.

There was just a case in Norway with what looks like a mom drowning herself and her 3 children. The mom and the eldest expired, while the two youngest were brought up and are in critical condition but alive.

Unfortunately the 4 year old is also dead now. :-(

And while it is a grotesque example, it further supports the idea that the younger the child the higher chance of surviving hypothermia.

Just out of curiosity - would one (say like a soldier) be able to effectively 'pre-emptively' wear a device in a backpack which has a permanent-ish lead to the circulatory system which does multiple things: Provides a constant flow of oxygenated blood which allows for higher endurance, longer "holding of breath", and in the case of severe injury, oxygenated blood circulation to prevent death (unless there is catastro…

Blood has been shown to oxygenate when passing in contact with semi permeable membrane with oxygen rich environment on the other side

Packing with ice packs is a standard component of TTM, generally in conjunction with other therapies (chilled IV fluids, etc). It's also the easiest step to take in a prehospital setting, which is why we do (this is a thing I've done with maybe a dozen patients over the past few years). I'm not just making this stuff up, it's based on actual treatment protocols and algorithms. We're talking about a naked, sedated pat…

Do you have any links to data showing effects on brain temperature from that treatment? Afaik interest has been low in carrying around enough ice pack capacity to make this viable, and with lacking data for it even working, whereas head-cooling packs with circulating liquid through a cooler takes little space, cools way more efficiently and required no other maintenance after insertion into the patient in the ambulan…

Overcooling is more of a risk with I've packs than not cooling enough. It's much less of a concern in a prehospital setting though, since we're not with the patient that long. It's more of an issue in the ICU.
