First Post - ResMed AirSense 10 - Clock Setting

Hi all,

CPAP newbie here.

I am using a ResMed AirSense 10 Auto Set and have been on it for about 3 weeks now. A couple of questions if I may.

1. I travel between time zones quite a lot and I can't see where to change the clock, with or without the SD card inserted. I have googled it, but people say they do it, but not HOW ???

Checked the user manual but no luck, and I am not in my home country right now so can't go to the place I bought it from.

2. I am using a nasal mask after first trying the pillows but the skin irritation was too much. I am a natural nose breather so the nasal mask works well, BUT, yes there is always a but..... Every night for as long as I can remember my nose starts to block up. I have gotten around this by using a nasal spray. Works fine. But the length of time it works must be varying according to my AHI as for the last 4 days they have slowly been increasing and I can sure tell the difference !

If I had any doubt the CPAP was doing me any good, I have no doubts now.
I am not back home for another few weeks so unable to go and see my sleep therapist. Any ideas on what I could do to get the AHIs back down. I am going through the same routine every night and think I am used to it now.

Thanks in advance.

Hi All,

Very new to all of this CPAP stuff.

I believe my AHI events should be below 5, I am averaging 8, but they are fluctuating wildly, perhaps as I get used to it all.

I also switch time zones a lot and it is throwing my data out, I cannot find how to change the date/time as I wander around the planet, any ideas ?

Would love some advice as I go forward.

I am feeling better, much more refreshed and not tiring during the day. I know when I have had a bad night without even looking at the data !! :bigwink:

Any help appreciated.

Welcome to the forum.

I merged both your posts since they were essentially the same thing.
I removed your testing post. The reason you couldn't see your posts was because we have to approve new account posts before people see them. We had to start doing this a little while back because of spam bot attacks. Your should now be able to see your posts and you can now see immediately any posts you make.

There is a clock in your machine but I don't advise screwing around with it. Going forward is easy but going backward can create problems if you try to go back and there's already data in that session. The machine simply won't go back and you end up having to delete all data and starting over. Best thing to do is just ignore the wonky times. It doesn't really matter if the clock time is off...hours slept is hours slept no matter what the clock says.
The clock is in the same area where the run hours and machine firmware version is.

Congestion...might be related to the humidity setting. Some people need more moisture and some need less moisture.
What is your humidity setting?

The bulk of your AHI seems to be central apneas. Are you spending much time awake with the mask and machine on?
If you are then it is very possible that your machine is sensing awake breathing irregularities or pauses in breathing as some sort of apnea and these should reduce as your sleep quality reduces and you don't have so much awake time with mask on.

Now if you aren't spending much time with mask on while awake....the centrals might be from the EPR or exhale relief you are using.
You can try turning EPR off and see if the centrals reduce in number or not. There's a very small subset of people who use exhale relief that actually see exhale relief cause centrals. Sometimes all that needs to be done if that is the case is a reduction in exhale relief...other times it has to be turned off completely.

It's in the clinical manual, but, why bother?

When I first started using an APAP, many years ago, I used to be concerned about setting the correct time zones, but it didn't take too long to realise that it really doesn't matter much, as long as you have the data. Nowadays I leave my A10 clock set on AEST (my home time zone) all year, no matter where I am.

In most cases I am only really interested in the last few nights of data and I can easily remember when I went to sleep etc.

Good Morning,

Thanks, now I understand.

Sounds like more trouble than it's worth !

Set when I picked it up at 4.
Of a night I have had congestion problems for as long as I can remember. Before I sleep I use a nasal spray which works well, just not sure how long it lasts.

The bulk of your AHI seems to be central apneas. Are you spending much time awake with the mask and machine on? Not sure how to answer this ! I had a double knee replacement back in May 2019, since then I have had a lot of trouble going to sleep, once I do, I don't wake up again. In the last few weeks it has taken less time, but last night for instance seemed to take forever.

If you are then it is very possible that your machine is sensing awake breathing irregularities or pauses in breathing as some sort of apnea and these should reduce as your sleep quality reduces and you don't have so much awake time with mask on.
Sorry, don't quite understand this

Now if you aren't spending much time with mask on while awake....the centrals might be from the EPR or exhale relief you are using.
You can try turning EPR off and see if the centrals reduce in number or not. There's a very small subset of people who use exhale relief that actually see exhale relief cause centrals. Sometimes all that needs to be done if that is the case is a reduction in exhale relief...other times it has to be turned off completely.
[/quote]based on my answer above should I try to turn off ?

Thanks so much for your reply.

Go here and read and watch all the videos.

See if that explains centrals and awake/arousal breathing a little better.

You can try turning EPR off and see if it makes any difference or not. It won't if the centrals are related to awake/arousal breathing irregularities.
Your choice....worth trying though just to see and answer that question.

To be honest I suspect the bulk of those centrals are probably more related to not sleeping and you are getting some false positive flagging from pauses in your own breathing. Asleep breathing is very regular and rhythmic and awake/arousal breathing is very irregular but the machine only measures air flow. It doesn't have a clue if you are asleep or awake.

Hi Pugsy,

Thanks for the reply. It was suggested in another forum I try turning off EPR so I will give that a go tonight.
Does Clean Airway = Central Apnea

Turning EPR off would be the first thing I tried and while it may or may not be the answer...it's a starting point in your detective work and something that is easy to do.

I have a friend that uses a slightly different machine than you do as she has the equivalent of 4 cm EPR available on her machine and you can only go to 3 cm exhale relief (drop in pressure) and she has the centrals with exhale relief problem.
At 4 cm drop she gets about 15 centrals per hour but at 3 cm drop she doesn't get more than maybe 1 or 2 centrals all night long.
So there's a wide range of options if you find your centrals are caused by exhale relief. You might be able to just reduce it or you might have to have it turned off totally.
Everyone seems to react a little differently.
She happens to need and use pressures in the upper teens so some form of exhale relief is actually needed for her comfort. We got lucky in that there was such a dramatic change in the number of centrals just from a 1 cm difference in the drop during exhale.

Hi Pugsy,

Have you watched Big Bang Theory ? I ask as I feel like "Penny" when Sheldon is talking to her Still trying to get my head wrapped around all of this

Also Does Clean Airway = Central Apnea ?

Clear Airway apneas...equals central apneas.

SleepyHead/OSCAR was first written by a guy who had a Respironics machine and Respironics calls open airway cessation of breathing (central apneas) clear airway apneas.
Later on the software was updated to be used with other brands but the clear airway name stuck.

Hold your breath for 10 seconds. That's essentially a 10 second central apnea....no air is moving but the airway is open..you just aren't trying to breath.
Open airway...clear airway....same thing.
Everyone else calls them central apneas but Respironics calls them clear airway apneas.

A few centrals are normal and no big deal. We all have a few normal and/or occasional centrals. They are only a problem when they are present in really large numbers or cause desats or cause the person to keep bouncing out of sleep and not getting into deeper sleep.
So don't panic if you have a handful every now and then. Everyone has an occasional central apnea every now and then.

Thanks

Howdy all,

Tried this last night :

Now if you aren't spending much time with mask on while awake....the centrals might be from the EPR or exhale relief you are using.
You can try turning EPR off and see if the centrals reduce in number or not. There's a very small subset of people who use exhale relief that actually see exhale relief cause centrals. Sometimes all that needs to be done if that is the case is a reduction in exhale relief...other times it has to be turned off completely.

This is the first night since I started that I had real issues, I woke several times and I felt like I was blowing my mask off.... Thinking I need to turn EPR back on ??

EPR: You can try it either way, and go with what you prefer.
The sensation of high airflow goes away once you get used to it.
