really amazing idea, but not without huge issues..Rather then try and act all smart and stuff Here's a good comment from the bottom of the article.basically all in all, you still need to exhale your waste gases. (Carbon dioxide) to avoid metabolic acidosis. (buildup of Co2 as carbonic acid in the bloodstream when it cant be exhaled/excreted.)
"This technology could, in fact, be lifesaving when used in a case where the pt’s airway is obstructed, or their ability to breath on their own is otherwise compromised. The “military” and “private sector” examples given above, however, seem to show a gross misunderstanding of how respiration actually works. In addition to adding oxygen to the bloodstream (through inhaling), people also need to eliminate carbon dioxide (by exhaling). Breathing is, in and of itself, an involuntary reflex. Regardless of the presence of oxygen in your bloodstream, your lungs will continue to try and expand and contract. Think of the pressure/bursting sensation you sometimes get while holding your breath. That wouldn’t go away simply because a Navy SEAL had injected some oxygen microparticles. This technology wouldn’t necessarily prevent a person from drowning, but it may help to prevent some of the damage that can occur to the brain and other tissues…the risk of inhaling water would remain present, and great care would have to be taken in the case of a near-drowning to prevent the lung infections that can come along with the aspiration of water and other substances.
Definitely a promising technology, but it’s important to have our fact straight before we go touting numerous advantages."

As a Paramedic/FF i really like the potential emergency medicine applications. i could see it working really well on dry land, working a code or someone in impending respiratory failure. i would want to have IV access, cardiac and ETCO2 monitoring (end tital CO2 ) in place to manage the patients vital signs and oxygenation. but thats carrying an ambalance full of toys with you, like i do at work.
the only way this would work on the river (imho) off the top of my head, would be as a resuscitative measure once a person had been pulled from the water post drowning or cardiac/respiratory arrest. I could see carrying this in a reasonably small first aid kit . (among other things, i carry a cpr mask, 1 vial of EPI 1:1000, 50mg Benedryl for IM injection ,and an albuterol MDI in my little kit, with a couple syringes.all this would be for a severe allergic reaction or asthma..) .
(i couldnt recommend anyone else doing this because the question of medical direction for carrying ALS drugs in wilderness settings is a whole nother topic. if you have the training then you'll know what you can carry or not, or if you have an MD who will back you up for river trips.)
[BUT... you could get a an Epi-pen, albuterol MDI inhaler from as an Rx from a doc, and oral benedryl from a pharmacy... as a layperson if you had the need and gumption.
one last thing, having syringes (sharps) out in the middle of the river is pretty rediculous imo...the only way it would work, and this is still reaching.... it would have to be a prepackaged thing like an epi pen or atropine/2pam injection kits the military use for chemical/biological exposures. i would be busy trying to swim rather then trying to jab myself with anything. people harpoon themselves with epi pens all the time.you would have to be stationary, like in sieve.
now the rapid -air system or the like is a reasonable oh shit measure. (which Steve Fisher actually used on the Congo held down in a whirlpool. but props to him as he is super badass and crazy for even being there...)
Anchorless, good on ya for reading about stuff thats not on mountainbuzz. i oughter try it sometime....
but im at work.... i just daydream about being on the river unless something happens...
