I have spoken with Resmed clinical support. They are asking for me to send in my data card. They want to see why this is happening. They believe it is rainout based and when the tubing is rained out it will exceed the max pressure sensing there is breathing trouble.
The following are the remedies from my experience and in talking with clinical support:
1) if you are in a humid area turn up the tube temp to 85. if you are in a dry area and using A\C the remedy is the same
2) use a tube sock like a snugglehose (available on-line) to wrap the line
3) make sure the tube has a "U" shape to it after it exists the machine so water doesn't reverse back into the machine
4) when you sense the machine is about to malfunction unplug it for about 5 seconds then plug it back in. This will cause a hard re-set and you should then be fine for the rest of the night.
5) i'm also getting a new tube in case the one I have is faulty as it is the only thing in common between the four machines I've had so far.
Keep us posted on anything you learn or figure out on your end. If you can, also call clinical support and see what info you get.
Normally you want to bring the hose on a continuously ascending path for several feet after the machine connection. This is to route any potential condensation back into the humidifier. With a U shape, any condensation will collect in the bottom of the U and after a while you will hear gurgling noises as the air passes through the collected water. There is no problem with condensation running back into the machine. It will just go back into the humidifier water tank unless one is not using a heated humidifier in which case one would probably never get condensation in the hose but water running back into the machine without a humidifier would not be good.
