BiPAP Auto M Series with Bi-Flex®

Please check with your local Respironics Representative to find out if this product is available for purchase in your country.

The ultimate in sleep therapy comfort.

The BiPAP Auto is the first device to combine auto adjusting pressure delivery with the breath-by-breath pressure relief of Bi-Flex. This is the most natural sleep therapy you can find, and it comes complete with our Encore Pro SmartCard technology.

BiFlex wave

Bi-Flex "softens" airflow at inhalation and exhalation, making breathing more natural and comfortable for patients. In Bi-Flex mode, patient-adjustable pressure relief is provided at the critical stages:

  1. EPAP to IPAP

  2. IPAP to EPAP

  3. During exhalation

Developed from the proven REMstar Auto, the BiPAP Auto features a proactive, multi-level algorithm that analyzes several parameters to monitor and respond to a patient’s breathing. A key parameter is flow limitation (a common early indication of complete obstruction). The auto algorithm performs two types of tests (Pcritical and Poptimal ) that allow the pressure to be maintained at a level at which obstruction is not likely to occur but is not unnecessarily high, thus maximizing patient comfort.

Proactive Algorithm-Flow Limitation

Pcrit test – IPAP is slowly decreased while the flow signal is monitored for indications of flow limitation. This test ensures that effective therapy is maintained at the minimal pressure.
Popt test – IPAP is slowly increased while the flow signal is monitored for improvements in a patient’s airway. This test ensures that maximum therapeutic levels are obtained.

This ongoing proactive search of Pcrit and Popt levels allows for maximum therapeutic effectiveness at minimum pressures without creating any uncomfortable spikes in pressure or patient arousals.

While the algorithm is performing its proactive tests, it is also monitoring the patient’s breathing patterns for occurrences of obstructive events such as snore, hypopnea or apnea. If a snore or apnea is detected, the algorithm will quickly but smoothly raise EPAP to eliminate the event. If a hypopnea is detected, the algorithm will raise IPAP to eliminate the event.

Treatment of Obstructive Events

Finally, the algorithm can also detect and respond to the presence of elevated leak by lowering IPAP levels to improve mask seal.
