I've been diagnosed with sleep apnea and will shortly be getting a c-pap machine from DVA. Could people who use these things tell me what they need/use for operation when not in caravan parks. I have a ute with a 80 a/h axillary and a 100 a/h in the caravan. We have a 80 watt solar panel but it is inside the ute when we travel. I have a Yamaha 2400 watt generator but dislike using it due to the noise etc (out of place in the bush). Anybody's experience or advise would be appreciated.
Thanks, Geoff

Hi Geoff

50 a/h per night is fine but please make sure you select the correct machine for DC use. Here is the info you require.

Hi Derek,
The current draw comparison between the CPAP machines that use an inverter and the ones that use converter are interesting. One would have to assume that the converter option if it was available would be the logical choice for all powered equipment that you take on a trip?

I have run mine on an inverter o/night with out a drama, if you are short of power for a night try hard to stay on your side, one night without will not be a great drama. Barnray

Sleep Aponea is not just about snoring.

Staying on your side might reduce the incident of snoring HOWEVER if you have been diagnosed with or suffer from Central Sleep Aponea then being on your side without a CPAP can be fatal. Central Sleep Aponea causes the brain to switch off the breathing function, this in turn reduces oxygen flow. Using a CPAP can help to control/manage this particular problem. Long term sufferers (without diagnosis or treatment) can result in Hypertension, Heart Disease, Diabetes and death.

I come under this one I think as I don't ever snore and have not been able to sleep on my back for many years.

I have been using my CPAP camping over the last 5 plus years. Its plugged into a inverter (pre 12 volt models).
I use about 20 amps per night - calculated using digital reader.
If however you need to use a humidifier then your amp usage will skyrocket and you may not have enough battery amps.
I have not had a single problem camping with my CPAP - and I conservatively have camped 200 plus nights during this period.

There is a lot of difference between

This a piece of P*** for me to advise on, as all of your circumstances described above except for your identity are the same as for myself.

My tests and diagnosis culminated in June last year and I ordered/stipulated a RES-MED 230/12V CPAP machine from DVA.

Just advised them that I am without 230V power on numerous occasions during the year and required a dual power machine.

The RES-MED machine is a sensational setup for size and ease of use and comes with a 12V 'power pack lead' similar to that of laptop.

Mine is an S8 series model and was supplied approx 2 weeks after the documentation was submitted to DVA.

Just to be clear - the 12V power pack lead is an optional extra and you have to request it as a separate item.

Just 'plug & pray' from your 12V Aux Bat. NO requirement for inverter.

Hope this helps you.

I, too, have sleep apnea and use a device from Somnomed (see www.somnomed.com.au) - it's a bit like the teeth-guards that sportsmen use but are cleverly connected so as to slightly extend the lower jaw and thus open the airway.
I've been using it for almost 2 years and I now sleep through the night and unless I've been hitting the Chivas I rarely snore so SWMBO also gets a better night's sleep.
Worth checking out.

Geoff, I was diagnosed a few years back and was told that I would need to lose weight of "concentration camp proportions" to avoid it. I have a Resmed Autoset Spirit S7 a few years old now. A bit bulky in today's terms and need the humidifier, not recognised in the comments of Derek above as they require greater eergy.

In the ute, I had 2x80 amp hour batteries to run my 300w inverter. You need a good quality inverter though for the bigger 240v systems so the newer 12v a real positive. I look forward to changing mine over soon with some luck later.

Mate, the systems that track your useage like the Resmed ones are pretty good to have after diagnosis as they all your useage patterns. I just take a printout to my doctor for compliance and assurance.

I was diagnosed last year with severe sleep apnea. Unfortunately as much as I have tried I just cant use a cpap machine. I hate having anything covering my face.

Hi Pete
Know where you're coming from as I have the issue so after trying for a month I threw the thing in the wardrobe and decided to lose 12 kilos and hey presto no sleep disorder, and no health problems and I have regular checkups with blood tests and all levels are excellent
Cheers Ray
P.S This may not be the solution for everyone though

Geoff, I have used a 240v Sullivan APD2 cpap machine since 1994.
Used it on 240v at home b4 travelling and from a 300 watt inverter off a 200 ah AGM battery system charged from a 80 watt Solarex solar panel originally, then a 200+ Watt system more recently.

Never had any problem from either of the systems when used in the bush.

The 'larger' AGM battery system is the secret, as you will use less % of the total capacity, and it will be re-charged next day anyway.
