Have you ever assessed a dog on scene of a MVC

[medic417]

It would appear that the oxygen tubing could become "contaminated", but not the oxygen source itself (the bottle.)

You do discard the delivery tubing do you not?

So do you discard the low pressure regulator?

 

[medic417]

What proof do you have that it does become contaminated?

By your own logic in previous comments just because there has not been a double blind study to prove it doesn't does not mean its not.

A city water system is completely different. When it is shut down it loses pressure and creates a vacuum that pulls water from the houses. That is why back flow preventer's were mandated.

I am sure there are plenty of tests out there that have been preformed on this very subject. Do you think hospitals would be contaminating an entire O2 supply system on purpose?

How often are wall regulators changed out? If they were becoming contaminated, they would be required to be changed after every pt and fully cleaned.

You brought up the question, look up the research for yourself. It is not up to us to prove you wrong. It is up to you, to prove you are right!

so did you not read the excerpt or did you fail to comprehend it?

even with forceful coughing, co2 was measured only 5cm from the mask and only in a few patients. With the delivery system disconnected from the oxygen source(no pressure against expired gas) co2 was only measurable up to 1 meter form the mask.

I hope your kids aren't vaccinated. After all, according to Jenny McCarthy all vaccines do is give kids autism. Sorry, the burden of proof is on the one making the fantastic claims.

I believe the burden of proof now lies on your shoulders.

oops. JP beat me to it, though i will leave this here since i can not really delete it.

Some quick things to thing about when applying this case to masks used for humans in EMS

1. We don't use lower flow masks like they used in the study. I'm not sure what type of mask that they were using, but considering that only a delivery rate of 2-5 L/M was used, it's safe to say it wasn't a non-rebreather.

2. NRBs have one way valves which prevent the problem seen with coughing.

3. Higher flow rate would mean less penetration of CO2 into the line on the patients that actually were able to achieve it.

It is not quite comparing apples and oranges, but the underlying concept is still the same, right?

one could interpret the information from that "study", and the ideas are transferable to this argument, are they not?

All the reasons you have listed above, only make the idea of expired gas flowing back into the oxygen tank, all the more less likely.

Trying to belittle with ignorant remarks like the above does not improve your side of the discussion.

I have not made claims I have posed a realistic logical question asking for proof that it can not happen. So far the only one to make any attempt at proof is lifeguard.

And lifeguard I read it but if any amount of back flow occurs then you can not rule out contamination so then we should be using disposable regulators or filters. Why? If in a basic controlled study you get some back flow there may be worst case scenarios where it could be worse. But again I realize that there has probably been some worst case studies done as well but so far none have been presented.

Which was why I was pointing it out. I'm not sure if there are any valves on the dog masks though, which was the start of this little discussion.

See my posting about forgetting my first patient.

About geting hurt by injured animals, believe it.

 

[FLEMTP]

yes, ive assessed many dogs on the scenes of MVA's... and their husbands would agree .. they were dogs alright B)


































I know.. i know.. im bad... :blush:

To OP:

Does "Hey, Vern, lookie, it's a dog!". count?
