The oxygen concentrator has *much* higher pressure than the cpap.

How much air you can feel blowing out the cpap hose when it's not connected is totally irrelevant, because it's running at full speed, trying to pressurize your entire room.
Just for the record, after I have worn the CPAP mask for many minutes, I can feel the airflow out of the mask's vent 16" away or more. When set to 2 L/min, I can not feel oxygen coming out of the concentrator's tubing, but I know it is working if I put the tubing in a glass of water and see bubbles.

If those O2 adapters didn't work (they do) they wouldn't sell them. . .
I don't know where you lived, but around here we can buy plenty of stuff that does not work as advertised. Some is even mentioned on this forum from time to time.

Also, please note the advertisement say, "Return On Warranty Issues Only". Does not provide for return if it fails to work as advertised.

We live in a very litigous world. If those connectors didn't work then why was I given one when DME came to my home to set me up with oxygen for my CPAP machine?

I didn't use it. Instead I used soclean adapter so I could use my heated hose and not have to worry about oxygen hose running along CPAP hose.

With machine CPAP and oxygen concentrator running I could hear water bubbling in humidifier. I also used pulse oximeter to verify my oxygen saturation.

The adapter pugsy showed you works. If you want to know for sure for yourself get a pulse oximeter and see that your oxygenation improves.

You're confusing apples and window cleaner.

Your mask, when on your face, has a vent rate of approximately 20 to 50 liters per minute, your oxygen concentrator (according to you) has 2 liters per minute, are you surprised you can feel one further away than the other?

More importantly than that, the flow RATE has nothing to do with the PRESSURE of the two alternative streams of gas. the PRESSURE coming out of a concentrator, or indeed, a O2 tank is orders of magnitude higher than of a cpap flow generator, (as has already been mentioned, multiple times). Concentrators operate at around 20PSI, cpaps operate at around 0.2 PSI.

That is sold as licensed medical equipment, used in hospitals... I don't think so. Don't be stupid.

I ordered one of the adapters pugcy cited. I have a recording pulse oximeter -- that's how I saw by saturation falling off recently -- so I'll be able to watch the improvement when I begin using the adapter.

The simplest way to tell that the O2 is still flowing is to just look at the ball in the flow meter.

If O2 isn't flowing, the ball in the flowmeter will fall, cover the end of the hose with your finger...

True, but some hoses are kink and pinch resistant. Green ones are heavy duty. Jim
Instead plug the end with your finger, don't make a weak place on the hose, they are tough, bit they are not rocker proof.
