DEVICE: VOCSN Internal Bacterial Filter (00855573007402)

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).

A portable, pneumatic, device that, through a rapid shift in pressure via a face mask, produces a high expiratory flow rate from the lungs, simulating a cough. This technique is referred to as EWNP (exsufflation with negative pressure) or mechanical insufflation-exsufflation. This device is suitable for any patient with an ineffective cough due to, e.g., muscular disorders or paralysis and would typically be used to clear retained broncho-pulmonary secretions, reducing the risk of respiratory complications.
