So how long before this becomes the standard safety kit for moon/mars colonials?
I think since the moon doesn't have an atmosphere, the vacuum will quickly tear you apart from liquid evaporation anyway.

That damn social bar is covering text. What an obnoxious website.
This is early, but I want it, now. I have a huge number of questions. My mother has idiopathic pulmonary fibrosis, a disease that irreversibly scars the lungs, restricting breathing over time. My grandmother died of it; my aunt just had both lungs transplanted; my mother is at the front of the list for a double-lung transplant (and can be called in at any time - we all have to keep our cell phones on). There's every…
If this technology comes to fruition, it would increase the number of people able to survive until transplant. There already aren't enough lungs about though...
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.
(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.)

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).

Wow... he is good :)

How do you remove carbon dioxide?
Indeed! So now you've got 30 minutes worth of CO2 hanging around in your blood... Surely that's going to cause some issues? Anyone with some biology smarts able to explain if this would be a problem? That aside, I wonder what the nano-med applications are for this. For example an implant for high-risk patients that injects a dose upon respiratory failure etc. Heck if it were feasible such would be handy for anyone to…
