GoodKnight 420E Auto CPAP Machine Overview

This is an auto-adjusting CPAP machine which is set for a range of pressures, then seeks out and delivers the lowest level of pressure needed to keep the airway open. The pressure level will vary as needed, but it will not lower with each exhalation as a bilevel does. The auto-adjusting CPAPs were designed for patients who are unable to participate in a sleep study or whose pressure needs vary during the night according to their stage of sleep or sleep position. However, any patient will receive very comfortable therapy from this type of CPAP.

This product is no longer available. A suitable replacement for it would be the AirSense 10 AutoSet with Heated Humidifier. The AirSense 10 has a built-in heated humidifier to keep therapy air warm and comfortable during sleep and uses auto-adjusting technology to manage your pressure settings for you.

The Puritan Bennett GoodKnight 420E CPAP includes the following features:
  • Smallest, lightest CPAP on the market.
  • SilverLining 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.)
  • Automatic altitude adjustment.
  • Direct DC operation without the need for a DC/AC inverter, just a cable and adapter which are sold separately.
  • Automatic leak compensation.
  • Two washable, reusable pollen filters are included; optional ultra-fine filters are available.
  • Two year manufacturer warranty against defects.
