I don't get it. How are you going to get enough oxygen (trapped in pockets of) a 3cc lipid injection to stay functioning? I breathe 10x that amount of air in a second. Even if I only get 1/10 of that as oxygen into my blood stream,... what that 3cc delivers is still practically nothing.
- ScottBurson 14y agoLiquids are much denser than gases.
- Dylan16807 14y agoThe technique in the article is small bubbles filled with gas.
- gojomo 14y agoInhaled air is about 20% oxygen... exhaled air about 15%. So a small volume of dense oxygen might replace many breaths of much larger volume. (A speculative nanotech dream for decades has been a manufactured red blood cell replacement, able to store and gradually release far more oxygen than naturally available - allowing cessation of breathing for hours if not days.)
- icegreentea 14y agoBreathing only extracts ~25% of the oxygen in the air (ie, the air we inhale is ~20% oxygen, the air we exhale is roughly 15% oxygen) (just as an FYI). I'm having a hard time seeing where you're getting 3cc from? I'm looking around the article, as well as the one that tokenadult posted, and I can't get a volume listed anywhere. But yeah, tidal volume (or a normal breath) is roughly 500ml, so you'll need like 25ml of oxygen supplied per breath. Normal adult does something like 20ish breaths a minute, so you need to put in at least 500mL of oxygen a minute to survive - at normal levels. You can probably get away with a lot less, especially if the patient is unconscious (somehow).
