Home Sleep Test results
#1
So, I have my results in from the HST. I am now officially diagnosed with having OSA. It's a relief to know the results even though I may not like them.

They determined that I have moderate OSA. MY AHI is: 21.9 per hour. Total recording time was 477.3 minutes. My lowest oxygen desaturation was at 82%.

They are recommending that I go on APAP therapy with a pressure range of 6 cm to 15 cm. I am awaiting further instruction from the sleep doctor on what to do next.

I am going to ask to do a self titration versus doing an in lab titration. I think that would be better since he wants me to do APAP instead of CPAP.

Does anyone have any good suggestions on what machine to use? I'm leaning towards the ResMed S10 or S9 model. Thanks for your help and advice so far.

The Autoset in either the 9 or 10 series should serve you well.
I have a personal bias toward ResMed machines; PR also makes fine machines.
Since the doc is recommending APAP, and you have a pressure range, I see no reason why you would need a lab titration.

I have a bias towards Philips machines. and I think that System One Auto or DreamStation Auto would serve you well.
Having said that; I'd like to suggest that you talk to a DME and find out if they let you try ResMed for a week and Philips for a week. Compare how you slept with each one of these and how well you felt in the morning than make your own decision.
Everything I post on this board is nothing more than an opinion expressed by an apneak. Normally, it's based on facts and experience but sometimes, I may get things wrong or not have all the facts.
I reserve the right to change my mind. Why? Because tomorrow I may know better.

I found out that I will not need a titration study. My sleep dr. already made a prescription for me and they need to verify my insurance.

I hope that when I go to figure out what equipment I want to get, that they will let me test out something instead of throwing me in cold turkey. I would like to get used to the treatment before I actually get my own.

Thank you for the replies.

Inky, beside the machine, you will have to choose a mask. If you are not a mouth breather, I suggest nasal pillows type as it is, for most, the easiest one to get a good seal and the head harnesses seem to be the least annoying. ResMed AirFit P10 seems to get be liked by most but not all who tried it. If you are back sleeper or during sleep don't roll much from side to side. Respironics DreamWear is a good one to try. If you are a mouth breather, I've no clue what to suggest.
Your DME may let you try several different masks.
To properly compare the machines, you have to use the same mask on both.
As for getting used to the treatment, DreamStation has a built in program for that. OTOH, you may not need much getting used to since your prescribed low limit pressure is fairly low. In fact, I'd suggest that you start with the ramp feature turned off and turn it on only if your 95% pressure gets to 9 or higher. 95% is the pressure that your APAP was at or below 95% of the time. If activated, the machine starts at that pressure.

I have a question about the settings that the doctor put me at. That is 6-15 cm. I have read that APAP machines have a low and high setting. What would I be classified at, high or low?

What is the highest point for low setting and vice versus for the high setting?

Also, I have been looking at masks a lot to see what would best suit me. I sleep on my side during the night but not the whole night through and then sleep on my back. As far as I know I am not a mouth breather but it does flap open sometimes during the night. Any suggestions on masks? I like the look of the Philips ComfortGel Blue mask but then of course I haven't tried any on yet. Thanks!

Hi Jamie,
APAP machines can be set at a low of 4 to a high of 20.
With that said, 4 is too low to start. Most say they feel starved for air.

If you are going to self titrate, their suggestion of 6-15 is fine to start.
You will need to download Sleepyhead software to keep tract of your apneas and pressure range.

Here is a link of good Machine Choices, and which to avoid:

As far as mask goes, it's trial and error. Be sure to ask for a 30 trial on mask, then you can return if it isn't working out and try another.

CPAP and APAP machines can be set anywhere between 4 and 20 cmH2O
APAP automatically adjusts the titration pressure within the limits set. In your case, the doctor set you up with 6 as a the low limit and 15 as the high limit. That means that the machine will start at 6. If it senses that you are about to have an apnea or the apnea is happening, it will increase the pressure. After that, if it senses that another event may be happening, it will increase the pressure again. If not, it may decrease the pressure. However, it will not change the pressure to be outside of the preset limits. If your machine has a 90% function that is activated, next and each following session, the machine will not start at minimum preset pressure but at the top end of the pressure at which it was previously running for 90% of the time.
(the above is a simplified version)

An auto machine sort of titrates for you. If after a while you find you spend most of the night at say 8cm, then you can bump up your minimum pressure setting. I am finding the mask is a much bigger issue than the machine if you get a decent one. Currently using a P10 but I am not convinced it is the best one out there for me. At first they gave me a decent machine but a crummy humidifier. If you are getting a humidifier, make sure you also get a version with a heated tube.

Unless you have another health issue, there is no reason for a lab titration since a current Resmed or Respironics machines can provide the needed information. Make sure your insurance will COVER the lab titration. Chances are, they won't after a home test unless your overall 02 rate was very low.
