Sleep Apnea and CPAP machines??


I have it.........How many others have to live with this? I use the humidifier when I'm at home. When travelling I just take the CPAP without the humidifier and seems to get by. Mine is an old S-6 that requires 115v AC. When I have mine in the coach and plugged into shore power it works fine with no problems. When we travelled from Orlando to back home(Regina) we had quick sleep overs in Wally World parking lots(with permission). I just ran the CPAP off the genny as it was running the air conditioner also. What do others do when actually boondocking in the boonies? Off genny, off inverter, or different CPAP(that runs of 12vdc)??

I used a small inverter (purchased at Wal Mart) plugged into the 12 volt plug in near the bedroom TV.

Diane's uses very little battery power even with a humidifier, 25 to 30 amp-hours a night with a pressure of 13. I wired in a 300 watt pure sinewave inverter and it worked great with two different CPAPs. Now with a residential fridge we just use the big inverter/charger at night. Diane finds the humidifier is a requirement for her, she feels like she has a cold if she doesn't use it.

I was afraid to try my inverter as it's a modified sine wave(older 2000 Heart Interface made for Fleetwood). Didn't want a chance of cooking anything. I don't know, maybe it would work fine?

The manual for Diane's first CPAP said it would work with modified sinewave. But our big inverter/charger is pure sinewave and I got the 300 watt pure sinewave one on sale for $100, so didn't try it.

Here is a 350 watt pure sinewave for $109 (same brand as my 300 watt) - http://www.donrowe.com/Samlex-SSW-350-12A-p/ssw-350-12a.htm.  

Edit: This is a good time to use a Kill-A-Watt to plug the CPAP in and get real values for total usage and maximum watts.

I haven't tried it yet, but I bought a battery that recharges with a portable (foldable) solar panel. I plan to use that for my cpap.

Also, some non-electric, though less effective sleep apnea treatments are Provent and the Aveo TSD.

 Weight loss can be very effective. During the time my wife gets her weight down, she doesn't need the CPAP at all.

The Respironics web site said their machines were okay with a 300 watt MSW inverter back when they did not have a 12 v humidifier. I used one and it worked fine.
At that time the Resmed web site said a MSW inverter was not okay and a true sine wave unit had to be used. I don't know if that is still true or not.

My last three Respironics CPAPs could run on 12 vdc - humidifiers and blowers both.
I still used the 600 watt true sine wave inverter I installed a few years back because it was easier than running a 12 volt line to the bedroom.

That all being said we very rarely did any boondocking and only used the true sine wave inverter one night when there was a power outage in the RV park.
Now since my wife has a CPAP and an oxygen concentrator for night use, our two house batteries wouldn't handle the load for both of us very long - I don't think even one night.

Most oxygen concentrators use a lot more power than a CPAP. But, there is hope, like this one - http://www.inogen.com/resources/traveling-oxygen/traveling-by-car/.

 Those are neat. A guy in the RV park where we spent last winter had one and it worked great. If we had decided to continue snow birding/RVing, we would probably have got one for her. Even if not boondocking it would have been great for use in the motor home and connected to 120 vac.

It would have fit in the bedroom. The Invacare unit furnished by Medicare is large and had to be kept under the dinette with a tube running back to the bedroom that had to be unrolled each night and rolled back up each morning.

It would be nice to have one now if we have to make overnight trips in the car for funerals and the like.

Used a MSW 150 watt inverter with  a phillips 110vac only and a respironics and never had a problem.  Most use less than 65 watts so shouldn't be an issue.  I have actually just used them on the road in the car without a problem both overnight and during a cross country.
