Switching from Cpap to Autopap - feedback please

[Alaska]

I have been on a resmed system 1 with heated humidifer since 2009 with pressure setting 6- using mirage quattro full face mask.

Since then i have significantly improved my physical condition so i took an at home sleep study to see if i was "Undiagnosed" of sleep apnea. I got a mild apnea (same as before) with an AHI of 10.5 (1 apnea per night and the rest were hypopnia's).

I have only had 2 days on resmed airsense 10( set at 5-20 still using mirage quattro and heated humidifier) and neither has left me feeling very refreshed in the morning. Today i have a headache and have sinus congestion.

Has anyone made the switch, if so is there an adjustment time? Or it could be that i am just coming down with a bug. It feels similar to as if i took some time off of using cpap, which is basically not feeling as rested and having a headache.

Either way any thoughts, experiences or feedback is appreciated.

What humidity setting did you use with the old PR S1 machine and what setting are you using now with the AirSense10 machine and are you using the heated hose with it?
The sinus congestion could possibly be from humidity (if you determine that you aren't coming down with a bug) being different from what you were used to having with the PR S1 machine.
It's possible that you need to change the setting...either more or less depending on what you were using before.

The headache may or may not be related to sinus issues.

In terms of therapy...use the available software to make sure that your current settings are optimal.

I started out on cpap for 4 weeks, switched to apap for a few months, then back to cpap. Not much difference between the two for me because my original prescription setting was a pretty good starting point. IMO, your apap has too wide of an operational range (5 to 20). Others can help you review your data and adjust your settings.

I see Pugsy is answering your questions, she's awesome! You can trust her advice!

on the s10 - tubetemp and climatecontrol are auto
system 1 - had dial set at 1 for humidity.

I got the heated tube, because in the winters i was getting condensation problems without it on system 1 due to cold temps at night in the house. Probably should turn that off in the summer as the house is about 80 degrees F.

I setup myair software and have sleepyhead software - not too educated in interpreting it yet though, but it seems to be ok, though i had large leak 15% first night and 8% last night

The setting of 1 on a PR S1 machine for humidity is going to be significantly less than the auto setting on the AirSense 10. So I suspect your nasal mucosa aren't used to and don't like the extra moisture.
The nasal mucosa are funny little guys in that they respond the same way to both too much or not enough humidity with the typical cold/allergy symptoms....congestion, pressure, runny nose, sneezing, sinus pressure, etc.
Your nasal mucosa are used to minimal added moisture and the AirSense is cranking out about 80% on the auto setting...so a lot more than you are used to using.

I suggest that you change the humidity setting from auto to manual and reduce the setting to probably 1 or 2 on the AirSense and at the same time change the hose air temp. Keep the settings independent of each other. Do you have the manual that explains how to do that?

Using SleepyHead takes a little bit of education as to what everything means but target the basics.
Leak, pressure and events. Don't worry about the other stuff.
If you want member input then post last night's detailed report so we can see what you are seeing.

I turned humidity to 1 and temp of heat tube to off. WIll post some photos of graphs, either today or after i get more data.

Update - Last night - night 3 i switched back to system 1 cpap at pressure 6. I went to bed at around 10:30 and really didn't sleep well, quite similar to when i don't wear a cpap, finally at 2:00 am i checked my pressure on my airsense 10 and it was around 10-11. Leaking has been an issue during this timeframe, i assume especially due to the higher pressure. It took a while to fall asleep again with the system 1, but i slept noticeably better, however my AHI on system 1 according to sleepyhead was at around 4 but its normally between 0 to 1.5.

I will be flying out for 7 or 8 days of work and its not practical to bring both machines, so i will have to delay this until i return. Although i wonder if i can program the airsense 10 to behave exactly the same as system 1 at pressure setting 6 constant?

If i base it all on how i feel i slept (which in this case having been awake quite a lot should be accurate) and how i feel the next day, so far its not looking good.
Disclaimer - on night 2 i did had 4 drinks with dinner over a 4 hour timeframe, so it doesn't surprise me to have bad results on that night. - Last night all was pretty optimal though.

Apparently sleepyhead will only show me the 2nd half of the night after importing card from both machines so i can't share both devices last night.

Sure. That's easy to do. Need to be in the clinical setup menu to make the changes.
In Auto mode just set the minimum pressure to 6 and the maximum pressure to 6 and it will give you fixed 6 cm pressure all night long.
Or change it over to cpap mode and set it to 6.

SleepyHead will let you mix machines but not during one 24 hour period as you found out.
It just can't do that.
For situations where you have used 2 machines within one 24 hour period I suggest you make a second user profile for one of the machines and use that second profile. You can't merge them but you will at least have the detailed data from both nights available.

There was a setting on how the exhale works, will just cpap mode make it exactly the same?

Thanks for the quick reply! And all the replies.

[Pugsy]

Exhale relief between the 2 brands of machines isn't exactly the same so you can't make it work exactly the same.

With the PR S1 machine exhale relief is based on the flow rate or think of it as how forcefully you breath and the most relief (drop in pressure) available on the System One was 2 cm at a setting of 3.

Exhale relief on the ResMed machine is a more direct 1 cm drop during exhale per EPR setting...so a setting of 1 for EPR will give you a 1 cm drop...a setting of 2 will give you a 2 cm drop...and a setting of 3 will give you a 3 cm drop but remember the machine won't/can't go below 4 cm so if you are using 6 cm fixed and set it to EPR of 3 it can't give a full 3 cm drop and will only give a 2 cm drop since it can't go below 4 cm. You would need to use 7 cm pressure to experience the full 3 cm drop if you use the setting of 3.

I suggest that you try each available EPR setting and just see which one feels more comfortable to you or more similar to what you were using and choose that setting no matter what it is.
If you are a rather strong forceful breather then there a good chance that you were getting the full 2 cm reduction on the PR S1 machine but even so the timing of the relief might not be exactly the same.
If that is the case I would start with EPR of 2 but I do suggest that you try all settings and even try it with EPR turned off. You never know what will feel the best until you try it. Unfortunately with the 2 brands having totally different ways of delivering exhale relief we can't make them exactly the same.
