Resmed smart phone reports

[LSNewcomb]

Husband is using new Air Sense 11 Resmed machine. Old machine gave out after 6 years. We get reports every night regarding his scores on wife's cell phone. It's showing he removes his mask 20 times during the night. He does NOT. At most, he'll remove the hose, go to the restroom and reconnecct 2 times. No one can tell me what's going on. We cannot trust his scores. Can anyone shed light on what is happening? Linda Newcomb

I have the same machine, I have noticed even if you pickup a corner of the mask to scratch my nose it will record mask off. Anytime it sees free airflow it'll record a mask off.

That's part of the reason that we say that MyAir is useless for anything meaningful.

Why do you care...the score means nothing. Only you see it. The reason you are using this machine is to sleep better with a low AHI. That's all that matters.

. . . MyAir is useless . . .

Everything I need to see is on the screen the next day.
Some may need Oscar--others are just fascinated by it--it's all good.

As much as many want to turn this into a topic about how useless MyAir is, the OP may be identifying a problem that needs addressing.

First thing, the Mask on/off metric is misnamed. It really has nothing to do with taking one's mask. It measures how often the device is power cycled.

Did my air actually report 20 mask on/offs?
Did he actually turn the machine off and on about 20 times?

If the machine is reporting 20 mask on/offs and he hasn't been power cycling it, then there might be something wrong, and the machine is inappropriately power cycling.

Now, we can talk about how useless MyAir is.

MyAir won't help you verify this is the case. But OSCAR can.

Download OSCAR, stick an SD card in your machine. Power cycling can show up on the graphs. Look for breaks in the therapy that aren't explained by bathroom breaks.

My experience has been that masks on/off are also recorded on prolonged free flow. I've seen MyAir report a larger number of off/on than what I know I did.

In the end, all it does is affect the score. In myAir, focus on AHI, time, and Leaks.

My AS 11 doesn't power cycle like that .. I use OSCAR and unless I push the power button
it doesn't show a break in usage .. Air Leaks show up on the leak graph but the Pressure
graph is a continuous line ..
OSCAR is easy to use and provides much more information to determine if Your machine is
malfunctioning !!
Good Luck figuring this out !!

MyAir is excellent for motivating the population of CPAPers. However, it has very limited suitability for analysis and optimation of CPAP therapy.

It's showing he removes his mask 20 times during the night. He does NOT.

On the surface, this appears to be a serious issue. What are his AHI, seal, and hours used stats?

If your technical experience is uncomfortable with using OSCAR, get a free account at SleepHq and upload the link in this thread.

Have you checked that all the power connections are secure - wall outlet, transformer brick, machine?

Dog Slobber. I don't think the Mask off/on metric is about machine power cycling. I do think it's about the machine detecting free air flow as if there were no mask... e.g. if you disconnect the hose, or temporarily move the mask to scratch your nose, or whatever...

My wife's machine often records multiple mask events when she moves and adjusts the mask for various reasons (e.g. comfort, dealing with something else like her phone, or whatever). In OSCAR or ReScan you see it as breaks in the treatment... and it shows up on the summary as a mask event. When she first started I thought there was some issue with her adapting to the machine, but it's just her bedtime habits or sleep hygiene.

LSNewcomb, I use the reports on the phone as a quick metric, and mostly just focus on mask leaks and AHI. For anything else, I would use ReScan, OSCAR or SleepHQ.

I can absolutely guarantee that a mask on/off event is a power cycle.

I have years of OSCAR/MyAir that demonstrate this because they match exactly.

Having said that, the machine measuring the free flow of air can indirectly result in a Mask on/off, under the following conditions:

• You have SmartStart turned on (on an Air10) or SmartStop turned on (on an Air 11)
• There is a leak so great that your device interprets it as a missing hose / Humidifier

But what will happen is the machine stops therapy.

You will get a mask on/off event, but that will occur not because of the the increased air flow, but because a power cycle occurred.

In OSCAR or ReScan you see it as breaks in the treatment...

This is a power cycle you're seeing, and as described, it's the power cycle that generated the mask on/off.

The only time a power cycle won't generate a mask on/off event is when the therapy end and restart is immediate.
