Heated Humidifier

agteacher · Post by **agteacher** » Fri Jan 21, 2005 3:03 pm

I have a respironics remstar with a heated humidifier, and there are nights that it does not use much of the water. I do have the heater turned up to 5, but there are still nights that it does not use much water. Does anybody know any remedies or anything that may be wrong? My pressure is at 12, if that makes any difference. THANKS in advance!!!!!

Hi Steve,

Sounds simple, but make sure it's turned on. I'm in the habit of just putting on my mask and breathing to start the machine. The problem is this does not turn on the heater. Also if you turn off the air flow momentarily it will also turn off the heater. Also you can manualy turn on the heater to pre-heat the water but it will automaticaly turn of in 20min(?) if the air flow is not turned on.

Don't be offended if this is not your situation. I've neglected this several times and once missed it the whole night.

I have a remstar auto with cflex and the heated humidifier and I've noticed the same thing. I generally have the heat set quite low at 2, and put about 1cm of water in the tank. Sometimes it's empty in the morning, other times it still has about half that amount left. Either way, it still seems to work!
I'm no scientist, but I would guess it has something to do with the humidity and temperature of the air in the room whilst it's being used.

If the atmospheric humidity is high, the air has little water vapor carrying capabiltiy, thus little water is used. Conversely, cpap patients in low humidity run the chambers dry regularly.

Ditto maskedmechanic, Also if you use an auto and have a need for more pressure at times more water will be used. Also leaks, mouth open,etc.

Not a worry if all the machinery checks out.

Cheers,
