Tips for Traveling with Your CPAP Machine

One of the most common excuses for not wanting to use CPAP is that “I travel a lot.” Even after I explain that many people travel just fine with their CPAP machines, some people are stll reluctant. With advances in technology and increased awareness by the lay public, government officials and medical professionals about the importance of using CPAP for obstructive sleep apnea, traveling with CPAP, although initially a challenge, can be done with relative ease. People use CPAP on planes, and even go camping with it. With the FAA’s recent ruling and instructions on carrying and using CPAP on airlines, it’s become even easier to travel with CPAP machine. I know there are various types of PAP devices, but for the sake of simplicity, I’ll call these devices the generic name, CPAP.

Flying with Your CPAP

The Federal Aviation Administration (FAA) recently ruled that airline passengers must be allowed to use respiratory assistive devices, such as a CPAP machine (Nondiscrimination on the Basis of Disability in Air Travel – May 13, 2009). However, don’t think that you’ll just breeze by security checkpoints at the airport. Here are some common tips that are recommended when you fly with your CPAP machine:

1. Never check your CPAP machine.

2. Always have with you a prescription for your CPAP machine and your latest sleep study. You never know if your unit gets lost or stolen, or breaks down.

3. Attach a medical equipment tag, identifying the contents as such.

4. Let the TSA security agent know that you have a CPAP machine. Remove it from the back and have it scanned separately.

5. Request that security agents change gloves and wipe down the table before inspecting your machine. Wrap your device in a clear bag while being scanned to prevent contamination with germs and other chemicals.

6. Keep a record of the model and serial number in hand, just in case.

7. If you’re going to use your CPAP machine in-flight, check beforehand if there’s an outlet next to your seat, and if you have the right adaptor.

8. If the flight attendant says something about your CPAP being another carry-on, let him or her know that it’s a CPAP machine and under the Americans with Disability Act, it’s not counted as an added carry-on.

9. Consider having your doctor give you a letter describing the need for your CPAP machine.

10. Most CPAP units will automatically convert to the correct local voltage. Check with your instruction manual or manufacturer to confirm this. You may, however, need a plug adaptor, as well as an extension cord, in case your outlet is far away.

Tips On Water

Many people are so focused on the logistics of their machines, that sometimes they forget about distilled water. Make sure you have plenty of distilled water available if you’re going to use it on the plane, or at your final destination.

If you’re not going to use your CPAP device on the plane, then make sure you empty and dry the water chamber before flying (check out expedia for available flights!). If you’re planning on using your CPAP device on-board, there are two options to be able to pass large amounts of fluids past TSA security checkpoints: Have your doctor prescribe distilled water in a pharmaceutical grade bottle. A 500 mL bottle should hold about 16 oz. Another option is to purchase papFLASK, which is designed to pass through security checkpoints with ease.

For whatever reason you don’t have distilled water available, using bottled or even tap water is OK, but try to find distilled water as soon as reasonably possible. Mineral deposits in tap water can build up within the PAP machine and can cause damage if it continues long-term.

Camping or Backing Up with CPAP

For travel to areas that don’t have electricity, or in case you have a blackout, there are numerous battery options available. Each manufacturer will usually have a back up battery recommendations and adaptors.

For more extended periods, various people have written about using a 12 volt deep cycle marine battery with a sine wave inverter. There are numerous other battery options so do your research. Different manufacturers have different voltage needs, so also check with your manufacturer. Since a humidifier uses a lot of energy, most people recommend not using the humidifier if you’re only camping for a few days. There’s lots more information about batteries in CPAP support sites such as,,, or

Have A Back Up Plan

Some patients carry around their oral appliances with them whenever they travel, either using it in place of their CPAP machines or just in case the device breaks. Some people use both the oral appliance and their CPAP machines simultaneously. If you’ve never tried an oral appliance and you’re interested in an alternative option, it may be worth giving it a try now before you need to travel for long extended periods.

No More Excuses

With advances in technology and more acceptance by the medical community as well as the lay public, there’s basically no reason (unless it’s psychological) you can’t travel with a CPAP machine. With knowledge and some flexibility and creativity, anyone can travel with CPAP, even in the more remote areas of the world. There have even been descriptions of solar power being used to recharge batteries used for CPAP. If you travel frequently to the same location, consider purchasing a second unit. Prices for middle of the road CPAP models are in the $300 to $700 range.

The first major challenge is in finding a way to make CPAP work for you. The second major challenge is in un-tethering your machine from your bedroom. Many people are living vibrant and normal lives, despite having to use their CPAP machines while traveling. Or is it because they are using their CPAP machines regularly while traveling? You decide.

  1. I had no life until I got my CPAP so using the machine allows me to have a normal, vibrant life!! Use it!!

  2. Well, you’ve convinced me! I’ll always check my CPAP with my luggage as I always have. That’s just too much hassle or raises the potential of even more hassle going through security.

  3. Does anyone know if airlines have outlets for c-paps? Going to Europe with husband who has a bad back and would like to take medication but if he sleeps he will snore and annoy people. So is there an Airline who had outlets for c-paps

  4. Very easy to say have the doctor prescribe pharmaceutical distilled water in 500ml bottles but does the TSA really care if it’s in a pharmaceutical bottle? I would need at least a liter of distilled water for a 9 day trip. Carrying a liter of water with me seems impossible.

  5. At Countries I have travelled there simply, THERE IS NO DISTILLED WATER AVAILABLE AT ALL!!!! In many of them, distilled water is only available at hospitals for injections. I travel for over as month or two with my CPAP, what’s my alternative if NO distilled water is available?

  6. Ms. Barber,

    Water with any kind of additives are not ideal. Simple bottled water can be used for short periods. Good luck!
