DEVICE: DreamStation (00606959060593)

A portable, mains electricity (AC-powered) device, which may include rechargeable batteries, intended to assist noninvasive ventilation (i.e., without use of an artificial airway) using continuous positive airway pressure (CPAP) during spontaneous respiration, primarily to treat adult patients affected by obstructive sleep apnoea (OSA); it may also be intended to treat snoring. It is a small desktop unit with controls, and may include a built-in humidifier; the airway pressure may be automatically adjusted to help provide optimal CPAP through use of a sensor (auto CPAP). The device is intended for use in the home but may also be used in healthcare facilities.

A portable, electrically-powered device intended to provide long-term alveolar support for patients who do not require complex critical care ventilation. It typically uses positive pressure to deliver gas to the lungs at normal breathing rates and tidal volumes through invasive ventilation (i.e., with an artificial airway); it may also be used non-invasively (e.g., with a mask). It includes a control system and alarms, and may include a built-in humidifier. Several methods of cycling and ventilation modes may be used. It may be line and/or internal/external battery-powered for use in the home or a healthcare facility (including ambulatory).
