BiPAP is a method of breathing support that is often used to treat central sleep apnea and central sleep apnea(both OSA and CSA), but it’s not used for life support. Many of the components of a BiPAP machine are the same as the standard CPAP machine. It can provide the correct airway pressure to prevent or even correct disordered breathing such as all kinds of sleep napnea, hypopnea, air flow restrictions, COPD and snoring. Bi-level Positive Airway Pressure (BiPAP) with EPR (Expiratory Pressure Relief ) offers the ultimate in sleep therapy comfort. It combines auto adjusting pressure delivery with the breath-by-breath pressure relief for most natural sleep therapy. It also can provide non-invasive ventilation for patients with respiratory insufficiency in the hospital or home. Features: 1.
