Running out of water during sleep

babypenguini, are you sure you aren't having mask leaking problems too? I know my bro loses a lot of water in his humidifier when he has leaks. He has a beard, so never a completely perfect seal.

Ok, that said, the following item, sold by our sponsor, may help. They can tell you on the phone if it will or will not work with your Dream Station.

I was going to get one of those from my brother, but then the water problem went away when F&P changed the cushion for his mask slightly. Now, he has enough water to get through the night again.

I've never been able to use the humidifier on my bipap machine. If my nose is a little stuffy and I try using it it's always clogged my nose worse. Since I discovered I'm gluten intolerant and stay away from it I've not had any more stuff up nose anyway.

"I've never heard anyone complain about the ambient air he's breathing has too low humidity."

^I've made that complaint a number of times while on visits to Arizona, Nevada & select parts of California.^ Those areas actually use evaporative machines to cool/humidify the air in homes and buildings. Strings of tiny misting nozzles are used around outdoor seating areas, too. Bottom line, if PAP humidifiers weren't popular (for whatever reason), they would probably not exist. Humidifiers are a popular comfort item in many, many HVAC systems also, I'm guessin' that moist air is desirable for a lot of folks, at times.

Hi, just wondered if anyone had increased water usage with the Dreamstation has managed to solve the issue.

I have had 6 years using a PRS1 series 50 APAP with an Aussie hose and have recently bought a new Dreamstation APAP.
From the first night the amount of water used has greatly increased. Some mornings there is almost no water left.
In the 6 years I used my previous machine I only ever used about half a tank at most.

Setting seem to be the same.
Could it be because this has a built in heated hose (set at 3)?
Thanks

the tanks on the two machines hold the same amount of water. turn the heat setting on the humidifier down.

the setting of the heated hose doesn't have anything to do with the amount of water used.

The 50 series machines used a lot less water even when set to max of 5 when compared to my 60 series machine with a heated hose. I suspect I would see the same water consumption if I used a DreamStation machine. I think the non heated hose humidification system simply cranked out less moisture. I know my nose was much happier with heated hose humidification maxed than it was with non heated hose max humidity of 5.

Even though your Aussie hose is heated the machine still considers it a non heated hose.

Are you still using the Aussie hose or are you now using the Respironics heated hose? With the Respironics heated hose the humidity chosen is going to be more consistent and not so dependent on the ambient humidity so much greater chance for more water to be consumed especially if ambient humidity is on the dry side.

I am in Las Vegas right now. Water consumption has doubled with my S9 and ClimateLine hose with no changes in settings.

My water use differs significantly with the seasons.
Now that the relative humidity is over 60%, I always have some left.
In winter, at <20%, I have to refill at 5 or 6 hours.

I occasionally run into the issue of my humidifier drying out at night, but it has a direct correlation with the settings of my home's AC. My humidity setting is at 4 with a heated tube setting at 83 degrees and I do run the warmup mode. A larger water reservoir would be nice, but for me, it's far from a necessity.

I have no comment to add to all of the science talk so I guess I'll go catch some Pokémon.

it is important to remember that the machines measure how humid the air in the room is, and add extra humidity to bring it to a set level, so with drier air, like in LV, they have to use more water to get a desired humidity than they do in moister areas.

people see changes in the seasons for this reason (like Chunky says).

I knew this would happen so the consumption change was expected. What's rough is I forgot my simply saline to use during the day. I lived here for 5 years and my nose never did like the dry air here and that was before cpap.

well, I knew that YOU knew, but wrote it anyway, for others reading this that might have wondered why your water consumption went up out there in the desert I hope you're enjoying your time up there.

worst dry air I ever had was in salt lake city in the spring... constantly getting zapped by static whenever I'd touch anything, and got spontaneous nose bleeds... ugh!

I am one of those people who's tank runs dry during the night. I am afraid of machine overheating and catching fire.

I think it is more common than not. It is just not known how many people have this problem. Just because people don't write in doesn't mean there aren't many tanks going dry.

I have noticed in the past two weeks I run out of water in my CPAP tank. This happens usually after only 7.3 to 8.4 hours of sleep.
I then get woken up by a metallic smell, it smells like burning metal .

I have read some comments, and I am going to try turning the humidity down, and the heated hose temp down as well.
Are there any other suggestions that I can use?

I've used this CPAP machine since December of 2017.

nathan, welcome to the zoo. you are likely to get more responses if you start your own thread. and when you do that, please fill in your equipment profile.

take a look at the link i have in my sig which is a post geared to the new user when coming into the forum.

good luck!
