Resmed Elite II on/off?

[m2d1]

Would someone be able to tell me if there is a way of turning this unit off, short of unplugging it? I can't find an on/off switch and the user manual doesn't say anything about this.

Thanks

That's what the Start/Stop button is for, on the top of it.



As has been discussed frequently on this forum, the ResMeds continue to run for awhile to dry out the hose and make sure there's no humidity inside the case.

Thanks... but I'm looking for a way to power down the unit. Unless I'm missing something here the stop/start button does not power down the unit.

Yep, that button does turn the Resmed off. But it comes back on at a gentle, low pressure for 15 minutes or so to dry out any residual moisture. It will turn itself completely off if you just leave it alone. If you keep trying to turn it off it will keep coming back on to finish the drying out process.

Of course it "powers down the unit". If you want to totally remove the power to it, you either have to unplug it or put it on a good surge protector (which it should be anyway) and flip the switch when you want it disconnected from power.
The reason these machines keep power going to the chassis is because they're "ready to go" as soon as you put your mask on and start breathing.

No "ON/OFF" switch on those units.

If you want to totally power it down you will need to unplug the unit.

Keep in mind that after you turn it off in the morning the unit continues to blow gently to assist with drying out the tube.

I leave mine powered up ALL the time and have it plugged into a good surge protector.

Its an excellent feature to me, You know or maybe you don't, but if you have a machine that just powers down after using the Humidifer, then you know there are droplets of water in your tube and in the chamber. If you let that set all day the moisture can get in the machine and it wont' ruin it now or maybe in 2 years but 3 -5 years it will start to break down little by little, So its a neat feature to me and I dont' have to clean my hose every night , to dump out the humidifer water and then let it run and do its business, When I come back from work, hose is dry / chamber is dry, and ready for use.

I LOVE IT

Oh so THAT'S why my S8 Elite II keeps running, I didn't know it was for drying out the hose. I always disconnect the hose and leave it hanging on some hooks on my closet door to dry it out. I also didn't want to leave the hose lying around in case my dog all of a sudden decided it was a fun new chew toy!

Thanks! I thought my new cpap was broken. Hose dryer..who would have known?

Very close. The actual wording from the ResMed integrated humidifier manual is, "Note: In order to assist the heater plate in cooling, some flow generators continue to blow air gently for up to an hour after treatment has stopped. However, you can unplug the device from the power outlet at any time and allow the heater plate to cool without airflow."

It should be noted that this function will only occur if one of the ResMed integrated humidifiers is used. If you use a stand-alone humidifier, this blowing will not occur.

In my view, ResMed's explanation borders on the absurd. Water is a substance with a very high "specific heat"; a great deal of "heat" must be removed to lower its "temperature". The low-flow blowing will have minimal effect. And they readily state that helping the heater plate to cool is not really necessary. Den's second point, that it is done to "make sure there's no humidity inside the case", is far more cogent. When the blower is turned off, and the water in the humidifier chamber is still hot, heated vapor will continue to be released for some time, and in the absence of airflow it will diffuse in both directions: toward the machine and into the tube. It will condense on cooler surfaces, and under these conditions ALL surfaces will be cooler than the water vapor.

For this reason, I suggest in general that in the morning (or even at night if there will be a prolonged period of non-use), connections in both directions - between the humidifier reservoir and the machine - and between the humidifier reservoir and the main tubing - be disconnected. This will prevent the diffusion of heated water vapor, and better allow for drying of the main tubing.

As for whether ResMed's "continued blowing" feature actually helps with the tubing itself, I am doubtful that the low-volume airflow - which in fact continues to blow heated vapor into the cooler tubing - is beneficial rather than an added concern. My suggestion would be that the main tubing be disconnected to allow for passive drying, even if the "continued blowing" is functining. Opening the top of the ResMed integrated humidifier chamber accomplishes this, as well as partially severing the "closed" air connection with the machine, while still allowing for the "continued blowing" to do its thing.

None of my recommendations are based on any particular medical smarts. Just plain physics.

All of which is a far cry from where this thread began. No, the ResMed S8 machines do not have a POWER on/off switch, just a BLOWER on/off button. The previous generation of ResMed S7 machines - which also had this blower feature - did have power on/off switches. I know of no "positive" reason for their removal. Regards, Velbor
