CPAP FAQs

1 Can I still receive CPAP therapy off the grid?
Using a Transcend unit completely off the grid is not only possible, it is also quite simple! You use your miniCPAP when away from a wall power source by using the Transcend Solar Panel Charger to charge your Transcend battery. If AC power is not available, but you do have access to a DC power source, consider ordering our 12-volt mobile power adaptor, which can power the CPAP and recharge the batteries from a standard 12-volt power plug. A cigarette lighter plug in a vehicle is a prime example. Purchasing the P8 Battery, is the easiest way to ensure you’ll be able to use your miniCPAP off the grid.
2Can I travel with Transcend? Can I use it on a commercial flight?
Yes! You can carry your Transcend miniCPAP device with you on your flight. And, as a medical device, it will not count as one of your carry-on items. Make sure that you always carry your device with you as CPAP machines can be damaged by normal luggage handling procedures. Your doctor can provide an official letter stating that you need to carry your device with you, if necessary. Transcend is FAA-approved for inflight use with battery. Be sure to call the airline in advance to clarify procedures and in-flight policies.
3How long will the battery last in my Transcend miniCPAP?
We offer two battery options - the P4 and the P8. The P4 Battery provides approximately one night of sleep therapy at 14 cmH2O and the P8 Battery delivers up to two nights at the same setting. These averages are based on testing at 14 cmH2O and may vary depending on leak rate and altitude.
4Do you offer CPAP masks?
Our CPAPs do not come with a mask as they are designed to be used with virtually any CPAP mask on the market today. Use your miniCPAP with a nasal cushion, nasal pillow, or full face design. For the ultimate in freedom, you can choose the mask that works best for you - which is quite common with contemporary CPAP offerings.

Humidification

1How does the Transcend 365 miniCPAP humidifier work?
The Transcend 365 miniCPAP is the first and only CPAP system to use patented Capillary Force Vaporizer™ (CFV) technology. CFV uses wicking action to pull water from your reservoir and deliver warm, moist air to you only when you inhale. Rather than using a heated plate to warm the water in the reservoir, as most heated humidifiers do, the 365 miniCPAP uses vaporization to deliver humidification in the same fashion a nebulizer would deliver vaporized air to you. This special method for humidification delivery uses about half the water of a standard heated humidifier and much less energy. That’s how the Transcend 365 miniCPAP humidifier can be so small and portable, deliver full humidification almost immediately, and can even operate on battery power!
2Can I pack my Transcend 365 miniCPAP humidifier with water in the reservoir?
No. Doing so risks water entering the CPAP device. Always completely empty your humidifier reservoir before transporting it.
3Can I use tap water with the Transcend 365 miniCPAP humidifier?
No. The 365 miniCPAP humidifier uses a special heating element that will become corroded from the hardness chemicals in tap water. Please use distilled water. If distilled or purified water is not available, use the optional Transcend 365 miniCPAP Water Filter, which will allow you to use tap water to fill your device. Distilled water is always the best choice.
4What should I do if I forgot my portable Transcend Water Filter and can’t access distilled water?
The hardness chemicals in tap water can quickly corrode your humidifier. The Transcend 365 miniCPAP measures the hardness of the water in the humidifier reservoir. If tap water is present, the humidifier will not operate. Therefore, if you cannot access distilled water and do not have the Transcend Water Filter it is better to run your Transcend 365 miniCPAP without humidification than to try and use unfiltered tap water. The Transcend 365 miniCPAP will operate normally without water in the humidifier.

The 365 minCPAP AC power supply may be used in-line with these products.
5How long will the battery power my Transcend?

The Transcend P4 Battery will provide approximately 7 hours of operation at 14 cmH2O and the Transcend P8 Battery will provide approximately 14 hours at the same setting. These averages are based on testing at 14 cmH2O and may vary based upon pressure setting, leak rate, altitude and tidal volume.

The Transcend P10 Battery can power the Transcend 365 miniCPAP AND humidifier. Battery performance and humidity level will vary depending upon CPAP therapy pressure, breathing rate, tidal volume, leak rate, and altitude.

6Can Transcend miniCPAP and 365 miniCPAP be battery operated?
Yes, the P8 and P4 batteries will power the Transcend miniCPAP’s. The P10 battery will power the Transcend 365 miniCPAP’s and humidifier.
