The main difference is the backup rate. A standard CPAP (E0601) provides a single, continuous pressure, while a bi-level device (E0470) provides two pressure levels—one for inhalation and a lower one for exhalation. The backup rate in E0470 ensures the patient gets a breath even if they don't initiate it, which is crucial for those with central sleep apnea or neuromuscular conditions.

The devices have built-in modems or data cards that record usage. The supplier or a third-party service provider can download this data to show the patient is using the device as prescribed. This data is critical for reimbursement after the initial 3-month rental period.
