Study claims 100% o2 is harmful

[nat]

As a Midwife, this thread is very interesting from my point of view within a clinical setting. We routinely respond to compromised patients by, amongst other interventions, providing 100% O2 for up to and beyond 4 hrs.

This is often initiated by the Midwife whilst awaiting medical personnel to attend in the case of an emergency. Although it's not often realistically carried out, O2 is classed as a drug and should be prescribed by a Doctor.

I wonder what implications this will have in clinical practice as well as the impact these findings will have outside of a hospital... I'll have to keep my ear to the ground on this subject!

We are only talking about near drownings here and I haven't seen other studies other that those about Ant-Occidents and the fact that O2 is a poisons by product of all that is green! I think in the scope of this conversation it is about the reflective actions the body goes through when drowning! For other cases it is about keeping the brain cells flooded with O2 so that it enriches the blood that is MOVING through the system loaded with O2. I can't see a reason not to continue that practice. Having said that the above mentioned study did look at Heart attack victims in the ER, but again their hearts had stopped! It will take years of studies to change existing procedures!

We are only talking about near drownings? I took it from the study they were talking about any use of 100% O2.

No, just where the heart and respiration have ceased and the person is revived. It was first notice in Cold Water near drownings where people have been brought back after hours in cold water.

huh? The study was with young kids and their body functions when on different amounts of O2, or atleast how I read it. What's this about near drownings???

[Papa Bear]

I was referring to the one I mentioned about adverse effects on Heart Attack Victims! I may have drifted of the original study a bit? But I was referring the one that would most impact us as divers and potential near drowning victims, since its been a long time since I have been a kid! Sorry for any misunderstand!

Here is another I found: http://www.damninteresting.com/?p=860
Also for our midwife I found a couple interesting articles about using room air at birth rather the O2. Easy search on Google!

one more, but I knew I would find it! You have to love the internet!
