Tips For Traveling With Your CPAP Machine

December 17, 2020 by No Comments

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 still 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. CPAP

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. 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
