Thanks! I'll give it a try. It does explain why swapping the chamber solves my problem: I have to open and fill that chamber before I swap it in and it probably latches correctly. It seems like my AirSense 11 has very narrow tolerances when it comes to how the chamber fits into the machines.

My AirSense 11 has developed an intermittent problem. Sometimes after I reinstall the humidifier chamber after refilling it, an air leak develops from somewhere around it when I next start the CPAP machine. The screen reports a large leak and the machine shuts off. I'll try reseating the chamber rep...

Freedom V2 says they are TSA approved by being 99.9 watt hours (it has to be under 100) but teardown indicates otherwise. TSA actually allows batteries of up to 160 watts to be carried on, but individual airlines might not allow batteries that large. See here under "Lithium batteries with more than...

1) We will be visiting S. Africa, Botswana and Zimbabwe on our safari, and all 3 countries use AC, 220 volts. I assume that the camps will all generate AC/220 as well. Is that reasonable? I'd say that's reasonable. I would also assume that most batteries that advertise themselves as travel batterie...

A link to this backup battery type would be helpful. Here's the battery I use: https://exppropower.com/ The larger size (EXP96) lasts me through the night even with heat/humidity on. But YMMV, I use relatively low pressures (7-9), 76 degree heat, and auto humidity. Here is a travel battery with onl...

Is there a name for this device you described? I've not heard of this before. Or are you trying to describe a UPS? It's not a device--it is a function of some backup batteries. It works similarly to UPS, but I think the switch over from wall power to battery power isn't fast enough for sensitive co...

I'm going to assume, tobindia, that you don't want to attempt a homebrew solution and, like me, feel more comfortable with an off-the-shelf solution. It might help you narrow things down if you ask yourself these questions: 1) Do I want to plug my bipap into an AC outlet or a DC outlet on the batter...

The moment I fall asleep, I seem to sort of forget to breathe sometimes, and wake back up panicked. FWIW, I experienced this when I first started using CPAP. I might go through several episodes of this in a night before I was finally able to get past it and fall asleep. The good news is that I don'...

What do you do when you reach your destinations by air? Well, I'm pretty much a newbie and haven't had to travel yet with my CPAP. But there are hangers that are more portable than the unattractive monster I am using. At a pinch, something removable (say, attaches to the wall behind you with 3M Com...

I use a P10 mask. To avoid the problem you are talking about, I use a hose hanger. This is the one I use: https://www.amazon.com/dp/B0BYHDQ679 When you use a hose hanger, the hose doesn't touch your body. You might have to experiment with the right length of hanging hose that gives you freedom of mo...

There's a simple fix to the water compartment leaking water as you carry it: shut the water compartment before you carry it. Unless your water compartment is somehow defective, you can fill your compartment to max, shut the compartment, and turn it completely on it side, and it won't leak. (Don't ge...

The reason for the lower scores is that I am "short" sleeping a lot more. Atypically for me, I often wake up around 5:00ish and can't go back to sleep. what time do you go to bed? Typically somewhere between 10:00 and 10:30. According to Fitbit, I fell asleep around 10:30 last night, and woke up ar...

My subjective sense is that the quality of sleep I'm getting is quite good (I feel great), though I do notice I'm sleeping less (~7 hours real-time and about 6 hours on Oura/Fitibit with lower sleep scores [75]), but I feel pretty good so I'm not that concerned about the Oura scores. New CPAP user ...

In my opinion, if you want to measure blood oxygen reasonably accurately overnight, you'd best buy an oximeter for that purpose. I have an oximeter (a LOOKEE) and a Fitbit. The Fitbit reads consistently a little low. And although it claims to measure oxygen variation, the resulting chart doesn't alw...

Broken teeth and cavities are certainly NOT caused by a cpap machine, no way no how. How would it? It's possible that a CPAP machine could promote cavities by giving someone a dry mouth. Saliva helps combat bacterial buildup. However, snoring also gives people dry mouth and most people with untreat...
