Page 8 Transcend EZEX Sleep Apnea Therapy User Manual
Note Indicates a tip, explanation or feature to aid in understanding, or efficient operation
of the device.
Warnings
•Do not allow water to enter this device. Transcend EZEX should not be exposed to
environmental conditions where the system may get wet.
•This device is not intended for life support.
•The Transcend EZEX System must be set up and adjusted by a trained provider
before being used for therapy ramp and pressure.
•The air temperature produced by this device can be as much as 10ºF higher than
the temperature of the room. Exercise caution if the room temperature is warmer
than 90ºF (32ºC).
•Do not block or otherwise obstruct the exhalation ports of the interface. Follow the
manufacturer’s instructions included with your interface.
•This equipment is not suitable for use with oxygen or in the presence of a
flammable anesthetic mixture with air or oxygen, or with nitrous oxide.
•The Transcend EZEX system is only to be used with the supplied or recommended
accessories. Use of accessories not recommended may result in increased
electromagnetic emissions or decreased electromagnetic immunity of the PAP
system and may be potentially unsafe.
•The Transcend EZEX system is not defibrillation proof.
•Do not attempt to sterilize Transcend EZEX.
•If the device is to be used by multiple patients a main flow bacteria filter should be
installed in-line between the device and the breathing circuit tubing to prevent
contamination.
•The device should be used only with masks and connectors recommended by
Somnetics or a health care professional. A mask should not be used unless the
device is turned on and is properly delivering ramp or therapy pressure. The
exhalation port(s) associated with the mask should never be blocked. Explanation
of the Warning: The device is intended to be used with masks or connectors
specifically designed to have exhalation ports to allow continuous flow of air out of
the mask. When the device is turned on and functioning properly air flow from the
device flushes the exhaled air out through the mask exhalation port. When the
device is not operating, however, fresh air will not be provided through the mask
and exhaled air may be rebreathed. Rebreathing of exhaled air for longer than
several minutes can, in some circumstances, lead to suffocation.
