Scientists Invent Particles That Will Let You Live Without Breathing

I really don't understand how this is possible because I have it on good authority that medical research and weapons research can't exist simultaneously

researchers have designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can't breathe anymore. It's one of the best medical breakthroughs in recent years, and one that could save millions of lives every year.
The invention, developed by a team at Boston Children's Hospital, will allow medical teams to keep patients alive and well for 15 to 30 minutes despite major respiratory failure. This is enough time for doctors and emergency personnel to act without risking a heart attack or permanent brain injuries in the patient.

The solution has already been successfully tested on animals under critical lung failure. When the doctors injected this liquid into the patient's veins, it restored oxygen in their blood to near-normal levels, granting them those precious additional minutes of life...

Hmm. Sounds awesome, but how does it expel the carbon dioxide? You will have oxygen, but be poisoned to death from the carbon dioxide. :laugh2:

 

[rkell87]

good question, I was wondering the same, maybe that is why the limit 30 minutes, eventually you do need to get rid of the CO2?

I think that happens when you breath, this seems to by pass that action, and put the oxygen into the blood.

once oxygenated blood passes through the heart, it is severely de-oxygenated which is why it makes its way to the lungs to receive more oxygen and get rid of the CO2 that was a byproduct of being processed in the heart. As long as oxygenated blood passes through the heart I don't see how it can bypass this action.


I'm wondering if the CO2 builds up in the empty lungs and a simple chest compression every so often dispels the CO2 enough to continue working on the patent.


also I wonder what the effects are if you inject this stuff and you start breathing on your own a minute later

You can't expel carbon dioxide if you're not breathing. That is the point of injecting someone with this stuff. So they can get oxygen when they're not breathing.

When I first read the title, I was thinking this is perfect for SCUBA diving, though I suppose it would no longer be called SCUBA if you didn't have to breath while diving. :laugh2:

I thought about it more after I posted, and that's what I came up with. You have to get rid of the waste. I think this is probably for people who are not conscious. For scuba, your body would still try to breath something in.

When oxygenated blood is expelled from the left ventricle to the aorta and out to the body, it is very oxygenated. Now after the capillary beds is it deoxygenated. Returning to the heart via SVC or IVC to the right atrium, it now deoxygenated, and then pumped into the pulmonary artery to become oxygenated once again by simple diffusion from the lungs. Yes, O2 in and CO2 out, but CO2 is a byproduct picked up in the systemic circuit. The chest compression as a means of the gas transfer needs to be accompanied by the 2 breath ratio afterwards. What I wonder is how this is binding with hemoglobin and myoglobin?

thanks for this.


as for the chest compression, why would you need the 2 breaths after if the blood gets oxygenated artificially? My thought is that once the CO2 is expelled the lungs sit empty until filled with CO2 again

 

[Zaxor]

I expel excess gas through my :moon: or I belch

This is the coolest thing I've read in very long time.

 

[Hostile]

I saw this in the move "The Abyss." That rat was breathing.

The rat was breathing in liquid oxygen though. This drug is injected into the bloodstream it looks like.

 

[jobberone]

Liquid oxygen is pretty cold man. That was a fluid supersaturated with oxygen. You'd have to have a way to remove CO2 from the fluid and also keep it oxygenated.

First I've heard of this but this sounds like a big deal.

This will help EMT's in the field and can save lives at the most critical juncture

 

[ethiostar]

About freaking time. I've been looking for an alternative for years now. I hate breathing on my own.

Aye, I didn't mean pure liq oxygen, just the part where he was breathing a liquid with oxy in it. Looked really cool in that movie though

So long as the airway was open, there might a little movement out of the lungs.

For the short term however, given adequate blood pressure the kidneys would likely excrete enough bicarbonate to keep things in check.

Carbon dioxide and water form carbonic acid which dissociates into bicarbonate and a hydrogen ion. Bicarbonate gets filtered out by the kidneys turning your pee more alkaline.

So where is the disclaimer that it will be an additional ten years before it comes to market?

And, the disclaimer that when introduced to the bloodstream may cause complications including;

Diarrhea
Swelling of the scrotum
Nose bleeds
Purple skin blotches
Headache
Liver failure
Lung contusions
Toe Jam
An erection that last longer than 4 hours.
