BPAP Treatment:

While CPAP provides a steady constant pressure to your upper airway, bilevel positive airway pressure (BPAP) treatment builds to a higher pressure when you inhale and decreases to a lower pressure when you exhale. The goal of this treatment is to assist the weak breathing pattern of central sleep apnea. Some BPAP devices can be set to automatically deliver a breath if the device detects you haven't taken one after so many seconds.
