M Series BiPAP Auto Bilevel Device with Bi-Flex and SmartCard

Category: Bilevel PAP

The BiPAP Auto from Respironics' M Series 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 Respironics' Encore Pro SmartCard technology.  The 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 three critical stages:  EPAP to IPAP, IPAP to EPAP, and during exhalation.  The device also features a proactive, multi-level algorithm that analyzes several parameters to monitor and respond to a patient's breathing.


  • Digital Auto-Trak Sensitivity tracks each breath so the unit can cycle between inspiratory and expiratory pressures based on patient's breathing
  • Encore Pro SmartCard and Data Management Software allow providers to track treatment progress
  • Enhanced event reporting tracks factors like apnea/hypopnea index, leak and snore
  • M Series heated humidifier is fully integrated, provides many options to improve compliance, and is available either on its own, or standard as a package with the BiPAP Auto(see Humidifiers)
  • Bi-Flex technology softens air at inhalation and exhalation to provide more comfortable therapy
  • Multilevel algorithm uses two different sets of analytical parameters to keep track patient's breathing

Data storage content for SmartCard includes:

  • Date
  • Time
  • Hours of usage patterns
  • AHI
  • Leakage
  • Snore
  • FOSQ
