Its a nice delivery system for patients without lung function, but its still gotta be less efficient than tanks of oxygen and some kind of recycling system.

Also, the oxygen would likely be delivered at a certain rate, which might not allow for strenuous activity

The weight of high-pressure tanks and valves?

Yup... Tanks, valves, and recycling machinery... All heavy stuff.

But its all oxygen, compressed in high volume, and the ability to recycle it... Over uncompressed oxygen molecules bound to fats, in a container of some type. I'm sure in larger quantities its still significantly better to use tanks. They will hold significantly more, and for significantly longer. There are times when the injected version will be better, but it won't be in a long term, large scale habitat.

Of course, when the tech is ready, there will be ways to easily calculate which method will be best for the application.

Interesting....but how do they scrub CO2 from the blood while the patient is not breathing?

I don't know. I'm trying to track down a copy of the original paper. I haven't had any luck finding it via my school's online journal subscriptions. I'll probably just request it through the school library.

Well if the lungs aren't working to inhale, it onlynseems reasonable to think you could not exhale as well.

Maybe CO2 cleansing is why the short duration.

RE: Injectable oxygen!
People with emphysema have that issue. The medical treatment that prolongs their lives is delivering extra oxygen for breathing. They dont have enough lung surface area to scrub the co2 from their blood. It causes all sorts of health issues.

Our red blood cells dont do a good job. They dont carry much oxygen at all. Plenty of creatures have done better than us in this regard.
