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.

Manufactured by Puritan Bennett.

Important Tips

This is a great bilevel machine, just as small and lightweight as the 420 series of CPAPs. Puritan Bennett released the component heated humidifier that will integrate with this bilevel. (The price of this unit does not include the humidifier.)

Bilevel machines come with a six foot hose, a travel bag and manuals. Masks are not included and must be purchased separately. We will be happy to help you with sizing and offer suggestions on current popular masks.

The 12 volt jack on this machine is not the same size as the 420 series cpap machines. Use the Respironics "12volt DC Power Cord (to connect CPAP to cigarette lighter socket)" for battery operations. Part # 1001956.

Error Note: If the machine displays an error 7 or "ER 7" this indicates an issue internally with the machine's blower. You can contact the provider of the machine to seek service if it is available, or the machine may need to be replaced.

This is the same type of plug adapter that would be used with a hair dryer or an electric shaver. World Traveler Power Adapter Plugs.
