1.4 Device Description

The Somnera Airbox is used with the Somnera Patient Interface (refer to IFUs) to treat obstructive sleep apnea in the home environment by providing positive airway pressure to a patient during each sleep night. The Somnera Airbox delivers room air to the patient, at a selectable pressure, through the Somnera Patient Interface hose and mask (refer to IFUs). The Airbox is transportable but must be connected to an AC power supply during use using the power cord supplied with the Airbox.

1.5 Indications for Use

The Somnera Positive Airway Pressure System is intended to treat Obstructive Sleep Apnea by delivering a therapeutic breathing pressure to a patient. It provides positive airway pressure during expiration and also during an incipient apnea. The system includes a dedicated flow generator and a patient interface, and is intended for use in the home environment. This system is to be used by adult patients weighing more than 66 lbs (30 kg).

1.6 Contraindications

• Severe bullous lung disease

• A pneumothorax

• Pathologically low blood pressure

• Dehydration

• Cerebrospinal fluid leak, recent cranial surgery or trauma

1.7 Warnings

• This device should only be used with the Somnera System mask, hose and accessories. The Airbox is not compatible with any other respiratory systems or accessories. Use of the Airbox with other systems or accessories could reduce the effectiveness of the treatment, result in improper operation or potential safety hazards.

• Do not use this device in an MR environment.

• A magnet is contained in the hose connector of the Airbox. Ensure that the Airbox is kept at least 4” (102 mm) away from any active medical implant (e.g., pacemaker, defibrillator) to avoid possible effects from localized magnetic fields. At this distance, the magnetic field strength is less than 0.5mT.

• Make sure you arrange the hose so that it will not twist around the head or neck.

The Somnera Airbox is capable of transmitting data to a mobile device through Bluetooth BLE connection. The Airbox contains a FCC certified Bluetooth radio module and complies with FCC PART 15 SUBPART C. The Bluetooth module uses Bluetooth BLE 4.1, operates within a frequency range of 2404 – 2480 MHz, uses GFSK, P/4 DQPSK, 8DQPSK modulation, and has a maximum RF power output of +10dBm.

The Airbox generates, uses, and can radiate radio frequency (RF) energy. Radiated RF electromagnetic fields were successfully tested to the IEC61000-4-3 standard from 80Mhz to 2.7GHz. These limits are designed to provide reasonable protection against interference in a typical residential environment.

There is no guarantee that interference will not occur from other portable and mobile RF communication equipment you may have in your home environment. If you believe your Airbox is being affected by other RF equipment, you are encouraged to try to correct the interference by one or more of the following measures:

• Increase the separation between the RF equipment and your Airbox.

• Reorient or move the RF equipment receiving antenna or cables

• Connect the RF equipment into an outlet on a circuit different from the one connected to your Airbox.

If you continue to have problems, consult your Airbox medical supplier for help.
