I have learned from personal experience the importance to me of sleeping only with CPAP. Not counting the years of undiagnosed and untreated fatigue and disaster, the few times when I haven't used my CPAP have turned me into a zombie for days. A few years ago I was ready to go to bed at a friend's home after a quiet New Year's evening when I discovered I had neglected to pack a critical connector for my CPAP. It was too late, I was too tired to drive the two hours to my place and the hazards of the road dictated I stay put. I 'slept' sitting up in the living room. I was a useless wreck the next day, and although I used the CPAP that night and thereafter, I did not recover for three days. This should have been my wake up call to set up a battery backup. A couple of partial power failures (leaving part of the house with power) and even short outages didn't get my attention. Besides, I wasn't sure how to rig up a battery backup system. Earlier this summer, I was forced to turn back and drive home, as my son shouldered his pack and began a weekend hike into the wilderness. I had no way to power my CPAP away from the normal household electric mains. We talked about perhaps finding a portable power solution so that I could enjoy an overnight canoe trip. Or so I might one day be able to do a long sailing cruise.
After I realized that I needed a source of back-up power for my CPAP, I started to collect information and do research. Towards the end of the year I felt I was ready to make my purchases, but decided to wait until after New Year's in order to avoid the crush of Holiday shopping. On New Year's eve I again spent a quiet, early evening and was ready to retire by 12:30. However, someone decided to steal a truck and promptly used it like a bowling ball (it was snowing lightly) to knock down three power poles. The whole area went black. After I checked the fuses in the house and called the Electric Company, I learned it would be at least 3 hours before power could be restored, meaning that I couldn't get to sleep until at least 5 AM! Weary, I packed my CPAP and toiletries, and drove through fog until I found a motel, finally getting to bed at 3 AM!
When the stores reopened for business, I started my shopping. When I finished, I had a battery, a battery charger, and an inverter that makes the kind of electricity my CPAP can use, along with sundry and various other gadgets. I added distilled water to the battery, attached the battery charger to the battery and plugged in the battery charger, and let the battery store up electricity for a couple of days. After testing the ability of the system to run the CPAP for several hours, I knew that I was ready for the next trick of fate. The next time the power fails, I will turn on my flashlight and don my protective glasses. Then I would disconnect the charger from the battery, connect the inverter to the battery and connect the CPAP to the inverter using an extension cord, turn everything on, and go back to sleep. Next time the power goes out, sleep will be mine to enjoy! And my hopes of going sailing, canoeing, and camping have become less a dream and more a real possibility.
Several technical possibilities exist, depending on your CPAP and your application. You can adapt the available electrical source, or provide your own power source.
Making, installing, and using a battery backup system can damage CPAP equipment, or may cause personal injury, fire, or explosion. Therefore, consult with your physician, home care company, and/or the manufacturer of your CPAP before you start. The services of a qualified electrician should be used.
