FAQ

Compliance Information (2)

What is AHI?

AHI, or the apnea/hypopnea index, is a measure of severity of sleep disordered breathing that combines apneas (stopping breathing) with hypopneas (lowered breathing level). An AHI of less than 5 is considered normal; 5-15 is considered mild sleep apnea; 15-30 is considered moderate; and >30 is considered severe.

How are the pressure and ramp set on Transcend?

Pressure and ramp can be set by a Clinician or DME on the Transcend CPAP by using either the compliance software supplied with the Transcend Sleep Apnea Therapy System or the optional LCD Programmable Base Station. Either must be operated in Clinician mode to make adjustments to the settings on Transcend.

Humidification (9)

Does Transcend have a humidifier?

Transcend has two options for humidification.  The Transcend Heated Humidifier uses a traditional water reservoir system to deliver heated humidification.  Transcend also offers patented heat moisture exchange (HME) technology to provide humidification during therapy. HME technology has been used in hospital ventilators for over 50 years, but Transcend is the first to utilize this innovative technology in CPAP therapy.

How does the waterless humidification system work?

The hygienic heat moisture exchanger (HME) is disposable and has no electric heating elements. HME technology works naturally with your breath to give you the humidification you need. During therapy, the small and hygienic HME captures heat and moisture from your exhaled breath, then it gives it back to you when you inhale to provide warm, moist air.

How long does a heat moisture exchanger (HME) last?

Different people require different levels of humidification. The HME should be replaced once you feel you are no longer receiving adequate humidification. Generally, this will be about once a week. Your Transcend waterless humidification system comes with four HMEs. Replacements can be ordered from your dealer.

Are HMEs reimbursable by insurance?

Yes, the HME is now reimbursable through insurance.

What is Waterless Humidification? What is an HME?

Transcend Waterless Humidification employs technology called heat-moisture exchange, or HME to provide warm, moist air during CPAP therapy. Heat-moisture exchange technology has been used in hospital and home care ventilation for more than 50 years and works by capturing the heat and moisture from the patient during exhalation and returning it on inhalation.

How long will the disposable HME insert last before it needs to be replaced?

The HME insert will last approximately seven (7) nights of use. Some patients requiring more humidification may need to replace the insert more frequently.

Is the HME insert sanitary?

Yes. Clinical research has shown that HME insert media does not support the growth of disease-causing organisms.

Why don’t other CPAPs use HME technology?

Special pressure monitoring technology had to be developed to allow the use of HME technology in CPAP applications. Only Transcend has this technology.
You should note that because this pressure monitoring technology changes the air flow pattern in the mask during exhalation, there is a noticeable auditory change from inhalation to exhalation. This change is generally not problematic, but for some patients it may sound louder while using the HME system.

Is Transcend Waterless Humidification technology compatible with all CPAP masks?

No. At this time the Transcend Waterless Humidification technology is only compatible with ResMed Ultra Mirage™ 2, Activa™ and Active™ LT and Respironics ComfortGel and ComfortGel Blue mask seals (cushions). Compatibility with other mask seals is in development.
Note that a special headgear and mask shell are required for using the Transcend Waterless Humidification. The mask seal attaches to the mask shell using specially designed mask seal adaptors.

Operations (6)

What should I do if I am experiencing problems with my Transcend?

Your healthcare provider or Somnetics Customer Support (877-621-9626) can assist you with any questions you may have.

Which CPAP masks can be used with Transcend?

Transcend PAPs can be used with all CPAP masks, including nasal cushion, nares pillow, and full face.

If the Transcend Waterless Humidification option is used, mask compatibility is important. See the question: Is Transcend Waterless Humidification technology compatible with all CPAP masks? for a discussion on mask compatibility.

To give you the freedom to use the mask of your choice, Transcend does not come with a CPAP mask. This is common practice with all CPAP offerings.

Can batteries be used at the same time the Transcend is plugged into another power source?

Yes. The P4 and P8 batteries can be used in line with AC power (home wall power) or DC power (such as in a car, boat or RV). By doing so, the P4 or P8 battery will provide an uninterrupted power supply, just like a laptop computer battery. In the event of a storm or power outage, using the Transcend battery in line will guarantee power for the therapy you need for a good night’s sleep.

How are the pressure and ramp set on Transcend?

Pressure and ramp can be set by a Clinician or DME on the Transcend CPAP by using either the compliance software supplied with the Transcend Sleep Apnea Therapy System or the optional LCD Programmable Base Station. Either must be operated in Clinician mode to make adjustments to the settings on Transcend.

Should “Dry Mode Cleaning” setting be run with or without tubing?

Drying mode serves as a method to dry out excess moisture remaining from device usage. As such, it is preferable to keep the hose and interface attached, but not required.

Can the CPAP be operated upside down?

The Transcend CPAP is designed for efficient therapy delivery regardless of orientation, thus you may seat the device in whichever direction allows for the most comfortable therapy.
