Re: Concerns on gas build up are cleared up...

[Guest guest]

In theory what you say makes sense, but in reality there are many

factors that could affect the physical make up of the air inside the

chamber. First placement of the person in the chamber, second

something brought into the chamber that affects the air flow , third

something else. That is why it is best to use an O2 meter in the

chamber, then you have a better idea of what the make up of the air

inside the chamber is and you are much better prepared to prevent an

adverse event. It is not as simple as air goes in and air goes out,

when you change the make up of the air going in. Flash points of

materails change as you increase the concentration of O2 and add

pressure. I guess I fall on the side of suggesting sound professional

training before operating any pressureized or enriched chamber... not

thinking it is simple when someones life is on the line.

Just my 2 cents

It seems to me that if your were to use 02 with the portable through

some hood method or a nasal device that it would be much safer than

your typical chamber.. Constant flow air comes in air goes out.

Assuming there is no increase in the concentration of O2 in a chamber

in which supplemental O2 is being added is more dangerous than

actually measuring and monitoring it. I have seen in my experience

the level of O2 can increase even as the flow continues. If flow is

reduced or restricted or even shunted or bypassed, increased

concentration is possible. I would suggest to potential HBOT clients

that it is better to monitor O2 in the chamber than to assume it is

not increasing.

One caveat to this is ,of course, is chambers that are pressurized

with 100% O2. Of course the O2 level is high and flashpoints are

lower than found in ambient air. All safety precautions must be

stricly adhered to in these chambers. I assert that it is not that

difficult to adhere to these safety practices and further it is an

added level of safety to adhere to them when ever in a HBOT chamber.

If possible, before operating a chamber with yourself or your child

in it, take a basic course on chamber operation and safety. You will

see the history and science of HBOT and learn much about this

fantastic science. It is not simple and assumptions should not be

made.

I would be interested in reading your research on O2 levels in a

chamber.

Syzmonski, I say these things with great respect and look forward to

learning what you have to say.

I am trying not to take this out of context, so correct me if I do,

but when you say " the 02 levels will not reach a level of concern as

long as proper ventilation is maintained. " ... what is a " level of

concern " for O2 levels?

Take care-

I have monitored our chambers many times. The highest build up of O2

has been 29% after 2 hours with 1 small lady inside. With 2 people I

have not seen the buildup exceed 28%.

In a Oxyhealth Vitaeris 320 with a 10 L/min Sequal Integra

concentrator. When I measure O2 inside the chamber it is 29%. When I

measure exit gases I get 22.5%. If I measure within 1 foot of the o2

tubing and the tubing is pointed in the direction of the analyser I

get 33-36% which I can't get to hold study so I average it to 34.5%. 2

foot from the hose I get 29%.

All the tests I did was over a period of 2 hours. I do not have a way

of measuring CO2 buildup but as the chamber is continually venting at

160 L/min I do not have concern for a buildup.

Compressor flow rate 160 L/Min

Sequal under pressure 6.8 L/Min O2. 10 L/min with no pressure.

Sequal at 1 ATA my analyzer says 92%.

In the Healing Dives portable chambers with an oxygen concentrator

delivering 95% oxygen, oxygen levels in the chamber will never exceed

25%. Oxygen levels in all hyperbaric chambers should be 28% or less

for safety purposes.

Look, I am not here to pick a fight. I am not here to get involved in

a which is better, safer, proper, this chamber is better than that

chamber war. A question was asked and I provided an answer based on

the measurements we have taken. Wars divide and the children suffer.

In in answer to your question above, I am concerned at 21%. Oxygen not

properly handled can cause fires. Yet when trained in safety

protocols, that risk is minimized and people are not afraid of oxygen.

And in answer to your question, as you increase pressure or increase

the amount of oxygen the risks do grow. Lets turn the question around,

do you know at exactly what level does o2 concentration reach a point

where it becomes too dangerous for the masses?

I originally thought the purpose of this list was to help the children

get treatment using HBOT and to get the expenses covered so more

children can be treated. From the infighting going on, I find this

list a bit divisive and the children may come out on the short end. I

sincerely hope my impression is wrong.

At our clinic, we have both hard and soft chambers. Doctor Neubrander

has found that in autism there is a group that needs the higher

pressure and the is an even larger group that needs more time under

pressure than the hard can give. (Lower pressure allows longer time

under pressure with oxygen) Does it not make sense that some children

will respond better to pressure and others better with time under

pressure? They are not all cut from the same mold.

Look, from our clinical data of treating over 40,000 hours and over

300 autistic children we find BOTH MODALITIES WORK! Stop the fighting

and concentrate on how we can get the masses to be able to know about

and afford HBOT treatment. Lets get back to the purpose the list was

designed for before this list becomes as one dimensional as 's

lists. I thought this list was different than what 's lists

were. If the party line is not opined than the posts do not show up

over there and not just my posts but my parents as well.

This is my last post in defending chambers. I will answer questions

about what we see clinically with either modality. I will be asking

questions on issues in making this treatment more available to the

masses. But hopefully this will be my last having to defend what we do

and why we do it.
