An auto BPAP machine, also called an auto-bilevel positive airway pressure device, delivers separate inspiratory and expiratory pressure levels and can adjust pressure support according to the selected therapy mode and model configuration. It is intended for patients who may require more pressure support, experience pressure intolerance, have residual respiratory events, or need help maintaining long-term therapy adherence. BMC Medical’s E5 and G3 Series include applicable auto-bilevel models with clinician-directed settings and multiple data pathways.
Auto BPAP is not automatically the right therapy for every person with sleep apnea. Product selection, mode, pressure range, and settings should be determined with a qualified healthcare professional. If you are comparing therapy types, this CPAP selection guide can help explain the broader decision context.
The E5 and G3 families offer different device interfaces, data options, pressure ranges, and model configurations. Confirm availability and exact specifications for your country or region.
E5 Series
The E5 B20A, E5 B25A, E5 B20A Plus, and E5 B25A Plus support CPAP, AutoCPAP, S, and AutoS modes. Applicable models use AirSync automatic triggering and cycling, while Plus models add a larger touchscreen, refined interaction, and premium design.

“Before treatment, I had between 74 and 76 apnea episodes per night. Today, with CPAP, that number has dropped to 3 to 5. The difference is simply life-changing.”

Auto BPAP may be considered for patients who require enhanced pressure support, experience pressure intolerance, have residual respiratory events, or have difficulty maintaining therapy adherence. The exact indication depends on the patient’s diagnosis, therapy history, and clinical assessment. A qualified healthcare professional must determine whether auto-bilevel therapy is appropriate.
The E5 family includes B20A, B25A, B20A Plus, and B25A Plus models with CPAP, AutoCPAP, S, and AutoS modes. The G3 family includes B20A and B25A auto-adjusting bilevel devices with specified pressure ranges, display features, data pathways, and optional monitoring configurations. Exact differences in accessories, connectivity, availability, and regulatory status depend on the model and market.
No. Do not change prescribed pressure, therapy mode, or other clinical settings without guidance from a qualified healthcare professional. Auto-adjusting functions operate within the applicable mode and configuration, but they do not replace clinical oversight. Contact your care provider if therapy feels uncomfortable or does not appear to be working as expected.
Compatible E5 and G3 configurations can provide automatic humidity and temperature control, preheating, water-level detection, and heated tubing support. The E5 documentation also lists an anti-reflux water-chamber structure. Humidifier settings, tubing compatibility, and included accessories vary by model, configuration, and region.
Start with the mask type and size recommended by your healthcare professional, and check that the headgear is secure without being overtightened. Humidification and heated tubing may help with dryness or condensation on compatible configurations. For practical guidance, review this mask fitting guide and discuss persistent leaks or discomfort with your care team.
On supported products and configurations, PAP Link can provide therapy usage data, nightly reports, therapy insights, and remote-management workflows. Healthcare professionals may review data and, where enabled, remotely fine-tune settings, while patients may view supported coaching information. Functions depend on the product, connectivity, region, and account setup, and PAP Link does not replace clinician judgment.
