One of those flaws being the removal of carbon dioxide from the bloodstream. A simpler problem is how to breathe it without gagging. Wouldn’t it be far easier if you just didn’t need to breathe at all?

Researchers at Boston Children’s Hospital thought so, so they created microparticles that can be injected into your bloodsteam and oxygenate it. Even if you can’t/aren’t breathing. And it can keep people alive for 15 to 30 minutes. Think about that. At worst, it’s 2/3 an episode of Seinfeld. At best, you could start a second.

The particles are pockets of oxygen in a layer of lipids, specifically fats.
