Oxygen feed into BiPap system

BTW I looked into the Venturi effect one of you mentioned - but the adapter doesn't show the physical narrowing the would have generated suction allowing low pressure air to flow into the breathing tube.

So thanks again.  My engineering degree is nearly 50 years old  and you can add this false alarm to the others over my career caused by a curious mind trying to understand how and why things work.

Did you consider that the O2 feed into the xPAP output tube is factors smaller in diameter?

  We should get together over a few Guiltiness and try to enumerate our false alarms -- loser buys. Mine were caused by thinking something was wrong due to confusion between NOR, NAND, and other tricky things developers put in their code to trip up software testers.

I think you guys missed my point - the concentrator supplies FLOW not pressure.

relative to each other, the o2 is high pressure, low volume, while the cpap is low pressure, high volume. the perceived high pressure of the cpap (less than .3 PSI) is not even enough to blow up a balloon.

Well I learned something new. Thanks for bringing up the question and answer!

It will supply enough pressure to get an air matress close enough. Did it once while camping on a cold night with a leaky matress. And a regular hose fits well over the matress valve by the way

The manual on my Respironics Everflo Q says it's compatible up to a pressure of 25 in the hose. Above that it will beeb theres a block. Check your manual.

Also you can instead of putting the oxygen hose into the cpap, put it directly into either a mask with a ventil for it or you can buy an adapter with a ventil. that way you can be sure its atleast reaching your mouth.

Mask with ventil is e.g. quatro fx from resmed(but it has leaking issues)
adapter looks like this : https://goo.gl/KLT893
