BiPAP AutoSV™ - Taking the Complexity Out of Complicated Sleep-Disordered Breathing INTENDED USE FOR BiPAP autoSV To provide non-invasive Ventilatory support to treat adult patients with OSA and Respiratory Insufficiency caused by central and/or mixed apneas and periodic breathing. HOW THE BiPAP autoSV WORKS The BiPAP autoSV sleep therapy system delivers optimal therapy for complicated sleep-disordered breathing patients utilizing a multilevel algorithm. On a breath-by-breath basis, the revolutionary algorithm uses Digital Auto-Trak Sensitivity to change pressure support, when necessary, to maintain a stable breathing pattern. In addition to this breath-by-breath adjustment of pressure support, the BiPAP autoSV algorithm also calculates the patient's spontaneous breathing rate and will automatically trigger a breath should the patient have an apnec event. This algorithm rapidly helps normalize respiration and return the pressure to the minimum required therapy pressure once ventilation has been normalized In addition to the revolutionary algorithm, the BiPAP autoSV sleep therapy system also offers other proven Respironics technologies such as optional integrated heated humidification and built-in digital data storage using Respironics Encore SmartCard and Encore Pro Data Management Software.

Severity is measured by the Apnea/Hypopnea Index (AHI) -- the number of episodes per hour of sleep. COMPLEX SLEEP APNEA Complex sleep apnea is a condition tht occurs when a patient is identified as having OSA, but with the application of Continuous Positive Airway Pressure (CPAP) to eliminate the OSA, the patient develops Central Sleep Apnea. The cause of complex sleep apnea is not known at this time. CENTRAL SLEEP APNEA Central Sleep Apnea is a pattern of breathing characterized by deep inspiratory cycle interchanged with complete cessation of breathing. It is typically caused by problems with how the brain controls breathing rather than an occlusion of the airway. PERIODIC BREATHING Periodic breathing is defined as alternating periods of hyperventilation with waxing/waning tidal volume and periods of central hypopneas or apneas. There are many forms of periodic breathing, one of which is Cheyne-Stokes Respiration (CSR) CSR is characterized by a cyclic pattern of waxing and waning during periods of apnea, and deep rapid breathing.
