Replacement for my Dreamstation PRO

[nonetheless]

Hi all. I am thinking Canada probably lags behind the U.S. when it comes to Philips coming around to repairing or replacing our machines up here. Logistics aside, I was given a loaner from my CPAP technician and it is a Resmed Auto AirSense for Her but he assured me that it is programmed to the male algorithm and to a fixed pressure reading as opposed to varying min and max auto variations.
In any event he also programmed AUTO Climate and 27C Tube temperature and heating set as 4. I find that there is very little water left in the reservoir in the morning and I sleep approximately 8 hrs. I have tried switching to MAN Climate and lowering the heating to 3 but it didn't help.

The main factor in how much water gets consumed each night is going to be your ambient bedroom humidity. The drier it is the more water will be needed to maintain whatever humidity selection you have made.
A setting of 4 for humidity is actually middle of the road and reducing it to the setting of 3 doesn't really reduce the humidity the machine will try to deliver and maintain. It's actually a very small difference.

You could maybe add a room humidifier to your bedroom and reduce the amount of water consumed but as long as it isn't running dry....just accept that you will use almost all the water and plan on filling the water chamber every night.
That's what I have had to do for 12 plus years now through both Respironics and ResMed machines. The only time I might not see much water used up is when it's raining and the windows are open and the ambient bedroom humidity is quite high.

Here's the provider/clinical manual for the machine in case you don't have it.

i must be too close to the border, then.

reported mine the minute i read about it here and haven't got a replacement yet.

i don't think there is any rhyme or reason to this recall.

There is no "algorithm" when set to a fixed pressure.

So, basically, ignorant tech has kneecapped an excellent machine.

I didn't have time to really address this whole "algorithm" BS your equipment supplier is feeding you but I will now.
I want people to understand their machines and not fall for DME BS.

The "algorithm" for these machines only comes into play when auto adjusting pressures are used.
Your DreamStation Pro is a fixed pressure machine and doesn't even have any sort of auto adjusting algorithm available.
He probably set your machine to match your DreamStation Pro pressure settings....but his telling you that is was the "algorithm" being for a male.....hogwash. Fixed pressure machines (or modes) don't do auto adjusting pressures at all.

Now the AirSense 10 AutoSet for Her....
it has 3 modes of operation
1...the fixed pressure mode like your DreamStation Pro...you set it at so and so pressure and that's what you get all night...no auto adjusting algorithm involved at all.
2...the regular auto adjusting pressure mode...commonly called apap mode...and an auto adjusting algorithm is involved with this mode because the pressure can go up and down as needed during the night. Example...I usually need 6 to 8 cm more pressure in REM stage sleep where my OSA is worse. If I were to try to use fixed cpap pressure I would need to use 16 cm fixed..all night long just to cover the 20% of the night I might be in REM. It's doable but man 16 cm is a LOT of pressure to be using all night. It wouldn't be much fun at all...especially when the rest of the night I might only need 8 or 9 cm.
REM stage sleep and sleeping on one's back...very common to see marked differences in pressure needs.
This regular auto adjusting mode has been used successfully by men AND women for many years. It's not a "for him" mode per se. It's just the regular auto adjusting mode that has been around since probably 2010 when ResMed did a major change to it's auto adjusting algorithm.
3 rd mode...the auto adjusting mode touted for women...it was target marketed as being "special" for women but in real life the different algorithm really isn't something that only women might do better with. Now it is different in how it responds but that difference isn't something that only women need....there are men out there that actually are doing better in the "for Her" mode than they do in the regular auto adjusting mode.
It's simply a different algorithm that works better for some people no matter what gender they are.
IMHO...ResMed has shot themselves in the foot a bit by insinuating that only females might appreciate this different mode.

So this is to just educate you....and there is zero auto adjusting algorithm in the fixed mode your equipment supplier set it at. He may not be doing you any favors...you might be like me. Having to use a higher fixed pressure all night just for short periods where you might need the higher pressures.
Or maybe you are having short periods of time where that fixed pressure isn't doing a good job...no one knows.

So I just wanted to explain exactly what the "for Her" machine was all about and the fact that there is no algorithm at all for any machine that is using a fixed pressure mode.
