Data Review Appreciate! - youbetcha - 09-12-2020

Hi all, thanks for the great help on this forum.

- Diagnosed mild sleep apnea (report attached)
- Doctor mentioned there was slight relief in my airway when moving my jaw forward, I am looking into a MAD. Breathing out I feel is sometimes an issue even on the device.
- Using a ResMed N20 mask
- Anecdotally feeling a bit little better, seem a lit bit more motivated, little less grumpy
- Looking to buy a second hand ResMed S10 Airsense Autoset for Her as my trial ends next week.
- I have been using the ramp function.

Many thanks!

Hi there, is anyone able to lend their advice and if I can make any improvements?

Thanks in advance

At 9 to 11 cm pressure on your Philips Dreamstation, your AHI is under 2/hour, and what remains is some flow limitation, hypopnea and obstructive apnea. I say this too often, but your issues would be better treated with a Resmed Airsense 10 Autoset as William learned a couple days ago http://www.apneaboard.com/forums/Thread-CPAP-mild-apnea-but-increasing-Can-anybody-provide-tips?pid=366587#pid366587

Based on what we're seeing the machine is helping, and your pressure is pretty close to optimized, but is not getting ahead of the OA events, so I recommend increasing minimum pressure to 9.5. If you zoom into the flow rate to show a 2-3 minute segment where the wave form is clearly visible, flow limitation is indicated by flattened tops on that wave. If you see that, then sometimes pressure, but usually pressure support (some contrast between inhale and exhale pressure) is the best remedy. I see very mixed results with mandibular advancement. Some people need and benefit from it, most are paying a lot of money for something that actually makes things worse and leads to other problems like TMJ. If you don't have bite issues, you may with MAD. Is your doctor a dentist or orthodontist?

Thanks so much for the feedback.

I have a Autoset For Her on the way and look forward to using it. I got it from secondwindcpap.

RE the MAD, I am a teeth grinder and worn a guard for the best part of 10 years. The sleep specialist and report mentioned he saw some improvement when moving jaw forward, so I have started looking myself. I will test just the resmed before looking at the MAD.

I will update once the Autoset arrives and I have some data to go through.

Thanks again.

Great! Congrats on the upgrade from secondwindcpap, I think you will feel a difference. You have a history of bruxism and I don't know of a connection of that with a retrograde jaw. I see a lot of people using CPAP and its alternatives through the forum, and the success rate of MAD is quite low other than t extract a lot of money from your pocket. Some people benefit, and I'm in no position to say you will or won't, however if you don't have a malformation that directly causes airway restriction, I'd advise against it.

Hi all,

Last night was my first night with the Resmed Autoset for Her. Any feedback on the results would be appreciated!!

@Sleeprider. I saw you mentioned raising to 9.5 above. I kept it as 9 on the new Resmed so I could compare it with the old machine. Should I still raise it to 9.5 based off the results?

Please see attached.

Many thanks

You AHI looks pretty good but you have significant flow limitations which will probably be reduced by changing EPR to 3 and increasing minimum pressure to the 9.5 Sleeprider recommended or even 10.


RE: Data Review Appreciate! - Gideon - 10-01-2020

Most of your pressure increases are associated with your flow limits. I'd first set EPR=3 to minimize then adjust pressure up to eliminate fluctuation if it is warranted


RE: Data Review Appreciate! - SarcasticDave94 - 10-01-2020

Agreed, EPR 3 should help flatten the flow limit chart. For what it's worth, your ResMed allows pressure settings incrementally by .2 cmH20 where Respironics allows changes in .5 only. So if you need it, you will have 6 pressure step settings to choose from between 9 - 10 if increases are suggested.


RE: Data Review Appreciate! - Sleeprider - 10-01-2020

What a bunch of mind-readers! EPR 3 should help, and do increase to 9.5.
