This specific BIPAP was designed to treat residents with Central Sleep Apnea. Central Sleep Apenea is a disorder, which your breathing repeatedly stops and starts during sleep. It occurs because your brain doesn't send proper signals to the muscles that control your breathing. BiPAP AUTO SV provides servo-ventilation, which is designed to adjust the level of pressure support to stabilize breathing and deliver the minimum level of mechanical intervention. This device has an auto rate back up designed to provide support during central apneas while encouraging spontaneous breathing.
