    Scientists Invent Oxygen Particle That If Injected, Allows You To Live Without Breathing

    New Medical Discovery
    A team of scientists at the Boston Children’s Hospital have invented what is being considered one the greatest medical breakthroughs in recent years. They have designed a microparticle that can be injected into a person’s bloodstream that can quickly oxygenate their blood. This will even work if the ability to breathe has been restricted, or even cut off entirely.

    This finding has the potential to save millions of lives every year. The microparticles can keep an object alive for up to 30 min after respiratory failure. This is accomplished through an injection into the patients’ veins. Once injected, the microparticles can oxygenate the blood to near normal levels. This has countless potential uses as it allows life to continue when oxygen is needed but unavailable. For medical personnel, this is just enough time to avoid risking a heart attack or permanent brain injury when oxygen is restricted or cut off to patients.

    Dr. John Kheir, who first began the study, works in the Boston Children’s Hospital Department of Cardiology. He found inspiration for the drug in 2006, when he was treating a girl in the ICU who had a severe case of pneumonia. At the time, the girl didn’t have a breathing tube, when at the time she suffered from a pulmonary hemorrhage. This means her lungs had begin to fill up with blood, and she finally went into cardiac arrest. It took doctors about 25 minutes to remove enough blood from her lungs to allow her to breath. Though, the girl’s brain was severely injured due to being deprived of oxygen for that long and she eventually died.

    Microparticle Composition
    The microparticles used are composed of oxygen gas pocketed in a layer of lipids. A Lipid is a natural molecule that can store energy and act as a part of a cell membrane, they can be made of many things such as wax, vitamins, phospholipids, and in this case fat is the lipid that stores the oxygen.

    These microparticles are around two to four micrometers in length and carry about three to four times the oxygen content of our own red blood cells. In the past, researchers had a difficult time succeeding as prior tests caused gas embolism. This meant that the gas molecules would become stuck trying to squeeze through the capillaries. They corrected this issue by packaging them into small deformable particles rather ones where the structure was rigid.

    Potential Future Uses
    Medical: There is the obvious medical uses where the microparticles can be used to save off death from a restriction in breathing due to inflammation of the lungs, collapsed lungs, and the like. It would be good to have these injections ready in hospitals and ambulances for when the time is needed.

    Military: Can you imagine a navy seals capability when they wouldn’t need to surface for air and could stay underwater for over 20 minutes? If a boat was to begin to sink, you could shoot yourself as the boat is going down to ensure you aren’t drowned in the under current of the sinking vessel. How about for toxic gases when a facemask is unavailable. The military could have a number of uses for such a medical advancement.

    Private Sector: Really this can be used as a precaution for anything nautical where the potential to drown is a real danger. Deep sea rescue crews could inject themselves prior to making a rescue, underwater welders can use it in case they become stuck or air is lost to their suits. The potential use for anything water related seems extremely worthwhile.

    Conclusion
    In the end, this is an amazing medical advancement and I cant help but recall the movie the Abyss when they took the pill, their helmets filled with air, and they were told they can breathe the water. Well what if they really couldn’t “breathe” water” but since the urge to breathe is natural, that must take place… even if you’re not breathing air per se. But your body was provided with enough oxygen for a time period by taking a pill. It’s just goes to show that anything, absolutely anything that can be thought up, can potentially one day become reality. Thank you scientists, for reminding me that people and their ingenuity are nothing short of awesome.

    Better than EPO, now the Tour de France without breathing !

    Thanks for posting, by the way, certainly interesting.

    If you ceased breathing (but maintained O2 levels this way) wouldn't CO2 build up and eventually become toxic?

    Smart question.

    CO2 is a totally different animal than O2. O2 does not dissolve easily in blood or water, but CO2 does, hence why a bottle of coke contains CO2 and not oxygen. Have you never wondered why they simply did not put oxygen bubbles in coke instead of CO2 ? That would possible only if your coke bottle had a thick steel wall because much more pressure is necessary to force oxygen to dissolve. In consequence, Oxygen is not really dissolved in blood, except for a very small part, like 1%; all the rest is carried in an undissolved way by hemoglobin.

    But CO2 is thus very different. About 5% of it is dissolved. The majority (60-80%) is present in the form of bicarbonate (HCO3). How does it get there ? Well, it gets there from combining with water. CO2 + H2O gives you H2CO3 or carbonic acid. The remainder, another 25% combines with hemoglobin and amino acids to form carbaminohemoglobin.

    H2CO3 or carbonic acid is unstable, and depending on circumstances the substance falls apart again. When you are really exercising hard this is exactly what happens; in the presence of an abundance of CO2, H2CO3 falls apart in H+ and HCO3 with the HCO3 being used to buffer lactic acid, and the remaining H+ ion being responsible for all those things that produce exhaustion, cramps, nausea. However, when there is an abundance of oxygen present, the H2CO3 does not fall apart in that way but goes the other way, and does produces CO2 and water (H2O).

    In other words, to come back to your question, what happens to CO2 depends on how much O2 is free, and if somehow sufficient O2 is provided in the blood without breathing, than the CO2 can be largely biochemically neutralized. Such process obviously require careful monitoring of blood gasses as is done in an operating room or ICU.

    In reality the problem is more complex than the above because some of the components mentioned above carry a electrical charge in the form of ions. An imbalance can therefore also create an electrical imbalance in the human body, and as you know muscles, espec. the heart are function by way of electrical charges.

    You may have noticed that in the article quoted by the original poster, it said: "The microparticles can keep an object alive for up to 30 min after respiratory failure." So, the time limit in there has to do with the increasing risk of dangerous imbalances if one would attempt to sustain such oxygen levels without breathing much longer.

    One should also not forget that the reason we breath is because of CO2, not because of O2. In other words, it isn't our need for oxygen that makes us breath, but our need to get rid of CO2. This happens inter alia via the chemoreceptors which are located at various strategic points in the body such as notably the aortic arch and the carotid.

    But there are many amazing things about the human body, many things that few people know. Did you know that, for example, humans can breath under water ? Believe it or not, but experiments have been conducted where someone has one of their lungs filled with water --yes, not exactly a pleasant experiment-- to have these processes monitored. I have not said that people can actually 'survive' by breathing under water, but there is actually some exchange of oxygen and carbon dioxide taking place between human lungs and water. The reason a human can't survive that way is because the transfer is very ineffective and minimal. However, as you know, this is exactly what fish do so much more effectively than we. Why are fish able to do this and we not ? Partly this has to do with the fact that in fish the surface where the exchange takes place (the gills) are flat, but in humans the alveoli are spheric ...
