Product Overview

This is a bilevel machine which differs from a CPAP in that it switches back and forth between two pressure levels, one higher and one lower, rather than providing one continuous pressure level. The pressure upon inhalation is higher to hold the airway open, but as the user exhales, the pressure drops to a preset lower level. A bilevel machine responds well to people with very high CPAP pressure needs, weak chest wall muscles, lung disease or other health problems that keep them from being able to exhale against a CPAP pressure.

This product is no longer available. A suitable alternative to this device would be the AirCurve 10 VA BiLevel Machine. This auto-adjusting BiPAP automatically chooses the inhale and exhale pressures for you so you don't have to manually set either pressure. It also comes with a built-in heated humidifier for optimal therapy comfort.

Bilevel is the generic term to describe these machines. BiPAP, for Bilevel Positive Airway Pressure, is registered with Respironics; ResMed uses VPAP for Variable Positive Airway Pressure.

The Puritan Bennett GoodKnight 425 Bilevel machine includes the following features:
  • Smallest, lightest Bilevel, BiPAP or VPAP on the market.
  • SilverLining 3.10 Data Management software option to download compliance and session data.
  • International power supply to operate on any AC current from 110 to 240 without adjustment to the machine. (An adapter may be needed to plug the CPAP into a wall outlet outside the US.)
  • Direct DC operation without the need for a DC/AC inverter, just a cable and adapter which are sold separately on our site.
  • Automatic altitude compensation adjustment.
  • Two washable, reusable pollen filters are included; optional ultra-fine filters are available.
  • 2 year manufacturer warranty against defects.
