Are Oxygen concentrators okay?

I have been using the m-tank at home and the e-tanks at work.  My medical supply company just got taken over by a different outfit and they don not distribute the m-tanks.  They claim they are not safe but couldn't tell me why.  They left me a m360 or something like that, I am at work and it was delivered today.  I think it is a smaller tank.  The delivery guy wanted me to arrange having a concentrator? ordered.  He claims it is simialr to an A/C in size but it converts regular air to pure oxygen at a continuos rate.  Are these effective for our needs?  HELP!!!!

The place where I am getting my oxygen from tried to talk me into ine as well, I told them know because I don't know if they are good enough and just wanted what I know works! I'm curious as well.

Chris?  You GOT a 'script for O2?  From your GP?
 
if so, YAY!!!  Smiley
 Cool - I just read your other thread.  
 
 
as to concentrators I think they would work well - they are pretty pricey though. I think we were quoted $1800 for one and I didn't want to push our insurance to see if they would cover it.  Birdman, sounds like your supplier is just being lazy - they should be able to supply you with any size you want or, at the very least, order it in for you.  The tank we get (and I pick it up at the supplier, Mike hoists it into the basement) is about 4 feet tall, maybe 8 inches diameter and weighs 75 pounds.  They ARE heavy to deliver but WAY cheaper than the concentrators!

When I asked about them, I was told that they do not produce 15 LPM at a continuous flow rate.  Some can for a short burst, but cannot sustain that level output.
 
If the above is true, regardless of the cost, they are worthless to our usage.
 
I don't know if it is true, but that is what I was told.

Oxygen concentrators can produce up to 15L/min but they come out as room temperature oxygen, not cold oxygen like in the compressed tank.
 
It can work because it is pure oxygen, but with Ch, the element of coldness is VERY important, it works faster the colder it is and it helps reduce the pain more quickly if its cold so if I am you, I would insist on the old cold compressed oxygen tanks.
 
If you only use oxygen for a normal respiratory condition such as emphysema then it doesnt matter whether its cold or not. But with CH, I would explain to the supplying company that medically, it needs to be cold.
 
Hope this helps.
 
Painfree wishes to you.

I have and use one, it reads only 10 lpm but it does put out more, ( I tweaked it). Yes it works. I'd try before I buy though. Hate to spend money on one only to find out that it doesn't put out enough for you.

O2 concentrators do not deliver pure oxygen. Most O2 concentrators deliver about 70% O2 when they are turned on. It can take them 10-15 minutes to get up to 90-95% O2. They never deliver pure O2. Those that have high flow rates take longer to produce higher O2 concentration levels. Tanks are much more effective for CH because they deliver 100% O2 at high flow rates immediately. Temperature doesn't matter because by the time the O2 can affect CH it's in the bloodstream at body temperature.

I've heard that two 8-lpm concentrators can be hooked up in parallel to deliver 16 lpm.
 
If I had the choice between that and nothing, I think I know what I'd choose.

I haven't read anything good about concentrators. I think someone here actually has 2 going in order to get a flow rate that's close to what we need.  
I really don't think it matters whether it's cold or not, except the cold may feel good for some of us.  
Stay with the tanks, sweetie. You know that they work.

Oxygen concentrators CAN deliver 100% pure oxygen and up to 15 L.min depending on the model.
 
ALL of the oxygen that you get in a hospital, the one that you find comming out from a wall outlet is all from a concentrator. However, since its for a hospital, the concentrators are of high capacity and they are very powerful.
 
I looked further into this and contacted BOC ( Vital air ) and they said the home use concentrators are a lot smaller and less powerful. They deliver between 85% to 100% oxygen.
 
Here is a sample of one with all the information.
 
 
http://www.vitalair.co.uk/vitalair/documents/Your_concerntrator.pdf
 
http://www.vitalair.co.uk/vitalair/clinicians/concentrators_clinicians.a sp?tabno=3&tabid=sc3
 
 
Temperature does help a lot. Coldness is also a very effective vasoconstrictor and anti-inflammation. Even breathing cold air helps a lot during a hit.
 
Therefore as I said earlier, insist on the tanks.
 
Painfree wishes to you.

Hey gang sorry O2 concentrators are low flow only they are designed to administer 2-4 lpm.   There are very FEW that are bigger but not for private usage and they are CLOSELY regulated by the government.

==>Please click here and check this link, it was already posted by Annette. <==
 
Quotes from the linked page and the PDF found there:
 
"Concentrators extract oxygen from the air and deliver the oxygen at concentrations of 85% or greater. The flow rates can vary from 0.02 litres per minute (by fitting a regulator, which is installed by Vitalair) or up to 15 litres per minute by supplying more than one concentrator."
 
"Performance:*
1-3 l/min: 95.5%-92.0%;
4 l/min: 92% ±3%;
5 l/min: 90% ±3%
*Based on an atmospheric pressure of 14.7 psia (101 kPa) at 70°F (21°C)."
 
The "high-capacity ZH Cylinder" is an addtional tank of high pressure (300 bar) oxygen? - Why not take a tank without the concentrator then?

So I guess Biker was correct....what a surprise...not.
 
As Friedrich pointed out, the higher you set the flow rate on a home concentrator, the lower the % of pure air. So...someone show me a link where you can get 15lpm at 100% on a home concentrator.
Matt...you may be getting more than 10lpm but do you have any idea what the % is? It's cool you were able to tweak it. Whatever the case, glad it works for you.
Has anyone tried a concentrator with the clustermasx? This may be a way to help a concentrator work. If you have one that produced 10lpm, that might be enough with a masx.....depending on what the % is coming out of the concentrator.
 
And we are talking about HOME concentrators since that is what birdman is inquiring about.
Saying home concentrators can produce 15lpm is misleading people. Yes you can hook them up in tandem but, one, birdman's insurance co isn't going to do that and besides, that's like saying jonny can bench press 500 pounds, but leaving out the part that he lifts 100 pounds, 5 times.
 
Breathing cold air does help sometimes but it's not because it's vasoconstricting IMHO. No one knows why, for sure, but it's most likely helping to cool down the vagus nerve (just like drinking cold water during a hit) and also the nerve ganglion in the back of the sinus cavity.
 
The difference in temp between the tanks and a concentrator is minimal and would play a small part in cooling these nerves, if any, but every little bit helps. Even if tanks produced the 02 at room temp, they'd still be the preferred method, and for the reasons Biker pointed out.
 
When using the "clustermasx" it's (temp) most likely even less of an issue because breathing the air out of the bag, just like any non-rebreather, it's warming to closer to room temp before being inhaled.
 
Birdman...if you get past all the nits we're picking....I think the concensus is stick with the tanks if possible.  
 
Bobw
BTW, if breathing cold air has vasoconstrictive and anti-inflamatory properties, I would think it might be even more effective and important for emphysema than clusters.

If only the insurance companies and medical suppliers were this imformed.  They talk as though they know what I need and what works for me.  I read somewhere on here once before that you just have to keep nagging until you get what you need.  Looks like that is gonna start.
P.S. - the tank they left me is an m60?  Anyone know how many hours it holds compared to the m tank?
Thanks everyone!  This is the brightest point of my day right now.

I have used a compressor the past two cycles so I can speak first hand on them.
 
First of all - Apria healthcare sent me a compressor that goes up to 15lpm - now that's as high as it goes, but it does go that high.  The compressor takes about 5 min to start producing 100% O2 - there is a light on the machine that starts red and will turn to green once the O2 gets over 95%.
 
In addition to the compressor I also get 3-4 large tanks delivered (the insurance company always assumes that you need the O2 constantly, not just "as needed"Wink.  I have NEVER had to use the tanks, I always used the compressor and it worked perfectly.
 
Obviously the beast is different for all of us, but I just want people to know that this is a legitimate option.  You may feel more comfortable with tanks, and it goes without saying that the compressor isn't an option once you're out of your house, but please don't say that compressors are not effective, because they have worked for me and they are a legitimate option.
 
I would advise getting both (if you have insurance) and deciding for yourself.

According to the "Ask Mr Happy' flow chart, it looks to be half-sized from a regular M tank.  Lugging the smaller tank may have less liability for the oxygen company because it's less cumbersome and less prone to any mishaps if dropped with the guard rail around the valve, as pictured.
  When I first ordered it was 4 "E" tanks at a time but when times got worse I inquired about 6 at a time and it was no problem, all same with Apria and insurance.  I kept one tank and so have 7, then order six at a time, one still intact in case of a missed delivery when it's important.    
  Maybe request 2 M60's per delivery to keep home capacity ok.  One time, order two but give back one saying the other's not quite empty, then you'll have 3 tanks.  Thereafter, when two are empty, order 2 at a time giving back two each time but still having one hooked up still.

Catching hits early is important.  Waiting for green light wouldn't be desirable when waking with one quick ramping.

The med supply company should be able to supply whatever you need. I doubt they don't deliver larger tanks do to liability. My last cycle I used an "H" tank It was delivered and set up by one person. That's the biggest tank available. If you can get a script for the cylinders instead of the concentrator, I recommend getting an "H" tank, it lasts a long time.
 
As for the hot/cold debate, attach a bubbler and ADD ICE if you want cold air.

My condenser was a gift from a friends of my dads, when the elderly couple that had it died it was donated. She knew I used O2 so she grabed it for me.  
 
I was worried about the same when I got it, was 10 lpm going to be enough? Was it pure? I brought it to Lincare to be serviced and tested, at 10 lpm it put out 90% O2. With the tweaking I believe I got it up to 12 or 13. Question is...does it work. Answer is yes. Would it work for you? Don't know, we are all different. I use a welders set up at work, works just as fast as tank air for me. I have a clustermasx, it travels with me back to forth from work. Bad thing about the condenser is that it runs on electricity....no power, no O2, I learned the hard way.
 
I do like the colder air, I run some tubing through salted ice water to cool it off, I got some 10 foot hose at the last convention, its pretty cold when it gets to the mask.

The medical supply companies would most likely rather have their delivery guys lugging smaller tanks so they don't get hurt and drive their insurance claims up. Just like any other delivery company! Grin
