Sleep Apnea and Backpacking

Q.} I have sleep apnea and sleep with a CPAP (continuous positive airway pressure) machine. Do you have any suggestions for a better night's sleep in the field?
Submitted by: Rick, Dublin, Ohio
A.} You might consider packing "The Everest"—a fully battery-powered CPAP machine—when camping. As far as I know, it's currently available from only one company: AEIOMed. They want a chunk of change for it, though—around $700 last time I checked. If you want to take a closer look, you can find The Everest by typing "battery-powered CPAP machine" into Google. Some people with mild to moderate sleep apnea have gotten relief with various outpatient procedures as well. You might ask your doc about it.

Hi!
I have obstructive sleep apnea. I did not do well the stored my machine for several years as the technician who gave me the test said I could do fine if I slept on my side. I was still tired and just quit basically yet to assure myself at least to some degree I slept on my side. I'm single so I had no one to complain about snoring until I traveled cross country with my sister and two nieces. They all complained and my sister said even though I was sleeping on my side it made no difference. I returned to using my machine. I did a lot of car camping while traveling cross country and bought an inverter so I could operate off my car battery. This is fine, however I am a "backpacker". I like to go for a week or so at times and go far into the wilderness. I discovered, before trying back packing again, that I could sleep apnea free by being in a sitting position. When car camping while traveling, if I was extremely tired, too tired to move the baggage around in my car and rolling out my sleeping bag etc. and needed to just turn off the car and sleep in my driver's seat, it worked. I could only recline my seat a few degrees. The angle was quite critical. If I was slightly too far back I'd awake myself with a loud snore and being out of breath. If I'm nearly upright I have no apneas. So I tried and tried to put my back pack under my shoulders. or take out contents and prop it to I would be at the right angle. I even used non-skid rubberized netting so I wouldn't slide on the slick waterproof tent floor covering I use etc. It's really a problem. I was wondering if there is any light weight way I can have support at least to just above my shoulders, best if as high as my head too, where I can sleep at nearly a 90 degree angle... 90 degrees meaning a 90 degree bend at the hips that's self-supporting where I don't have to try to prop things behind it, so I can be in the right upright position in my little 2 person mountain tent. Its a mountain tent where one can sit up at the highest point. Is there anyone else out there in my category who has been trying to resolve the same problem. Thanks for your assistance. Winfred0000

Through my research I have found a lot of interesting results about cpap equipment and the many effects it can have on people and their sleeping habits and sleep apnea. Did the cpap machine just not work very well for you? Thanks for sharing your experience it was been great reading all the different answers and experiences. In regards: www.cornermedical.com

People shouldn't make ignorant posts about individuals not needing CPAP. For those people that DO need CPAP, not using it leads to high blood pressure and subsequent heart failure, among many other negative health affects. It isn't always about positional sleeping. You can still have resistance to breathing on your side or on your belly. Therefore, simply using the tennis ball isn't a solution. And weight loss isn't a save-all either. There is a diagnosis called Upper Airway Resistance Syndrome (which I have) that affects thin individuals. Weight loss will do nothing for people with this syndrome. From the perspective of a clinician and a patient, use what your physician prescribes and find a way to bring it with you backpacking and camping so that you can enjoy your time outdoors and have energy to hike.

My husband slept with a CPAP for nearly a decade. He had 2 surgeries to try to get off of it-one for a deviated septum and one to remove tonsils and adenoids and they actually cut more away in the back of his throat to try to create scar tissue that would be more firm.
The ONLY thing that really helped was weight loss, he's not a big man, but he had a thick neck and the fat was pressing down as he slept, cutting off air. Sleeping on his side now, after getting under 180 (he's 5'10), usually keeps the snoring at bay.

Forget your CPAP. Most sleep apnea can be treated by correcting your sleeping position (called Positional Therapy). Try sleeping on your side. I wear a Rematee Bumper Belt for my sleep apnea, and gave up on CPAP a long time ago. I love travelling and my bumper belt comes with me whereever i go! it takes as much space as a pair of socks!
go to www.rematee.com and give it a shot!

Well truthfully i have found a remedy from a company that I was introduced to. They sell a natural pill. I have suggested now to many friends who have sleep apnea as well as I. We no longer use CPAP period. I would ask you to take a link at it http://www.natures-rite-remedies.com/site/index.php I would assume this would fit your needs on backpacking. I use it as well when i go camping and hunting....ITS AWESOME!!

Do try to find a qualified dentist or respiratory therapist who can customize a dental device (mouthpiece) for sleep apnea. There are different kinds of devices like the "Silent Nite" for different kinds of apnea. And they really work!

Get a CPAP machine that runs off DC power.

You then don't need a AC/DC converter. Then I have a 10 lbs battery that I charge and is usually good for 1.6 nights before I have to charge with a portable solar panel or through a wall charger.

This setup has gotten me through multiple international sailing trips and remote camping trips.

It is heavy setup, approx 10lbs with the cpap machine and batter. Heavier, if you take a portable solar panel (approx 3lbs more) but if your backpacking with good buddies, they will help distribute the weight between all of you to make it more comfortable trip!

Originally I had to research and calculate my own battery pack years ago. CPAP suppliers have caught on that there are active CPAP users out there. Here are some setups if you have a DC capable machine:

I am a Respiratory Therapist from Texas. Respironics (A Philips Corp. Division)makes a great device called the "Snore Silencer Pro". It is made for patients with mild to moderate sleep apnea. We usually get these prescribed for non-compliant patients, but if your backpacking, I'd rather take a mouthpiece than even the lightest home CPAP device any day. The device is fitted right in the Dr's office same-day and is supposed to be the most comfortable fit out there! Don't let OSA stop you!

The Everest weighs 2.1 lbs w/o humidifier. I doubt that includes the battery. The battery only lasts 11 hours. Not a practical soultion for backpacking but would work for car camping. I am going to look into the dental appliance. I have found it helpful to sleep on my side. It is also helpful to me to sleep at an angle less than horizontal.

Iíve been using a CPAP now for almost a year. I have severe obstructed apnea so I canít sleep without the machine. Now that camping season is back I figured I can probably get a portable battery pack/jump box with the car adapter and adapter for my cpap machine. This should work for car camping but I have to young boy scouts, my sons, that I was hoping to start backpacking with this year. Unless I get some saddlebags for our yellow lab I donít think itís going to work with all that extra weight/equipment. Has anyone dealt with this type of problem?

I traded in the bulky CPAP machine for a dental appliance years ago; have tried a couple different kinds of dental appliances to get a longer-lasting one. The cheaper one was about $500 (plastic molded at the dentist's office in hot water), the more expensive $700 (sent a cast of my mouth to a lab to make the appliance). The cheaper one broke about once a year, the more expensive one has lasted almoast 3 years so far. In sleep studies, sleeping with the dental appliance has had results comperable to the CPAP machine for my mild apnea (19x/hour without treatment, 2x/hour with appliance). It weighs very, very little and requires just regular toothbrushing of the appliance on the trail.

Short of a really, really long extension cord, there are few other options. That's why I had to give up backpacking/camping and stay in a lodge with power at Lake Clark NP in Alaska...but even then,since the generator shut down in the middle of the night, I had to buy a converter so my CPAP would run on a 12V car battery.
