How to adjust a Goodknight 420e and user manual

[dunnwes]

How can a person set the pressure on the Goodknight 420e without using the software? I just bought one from cpap auction and it didn't include the user manual.

Is there a site to download the manual?

The clinician menu is accessed by pressing the "hidden" button. If you run your finger over the keypad you will find an unlabeled key, I think that it is under or near the 'G' in Goodknight.

Puritan Bennett has a relatively new knowledgebase site here:

And you can find a PDF file of the users manual for the machine - though it won't teach you about setting it up.

One caveat about the 420E; you have to use a special hose that has a pressure sensing tube. The pressure sensing tube is about the same size as aquarium tubing and slips over a small nipple near the output. I understand that there is an adapter with a sensor tube that allows the use of a standard hose.

To access the clinical menu on the Puritan Bennett 420E, press down on the letters "Go" of the word "GoodKnight" on top of your machine. While keeping that little depressed area under "Go" pushed down, press the "Information Access" button on the top of the machine (the button with the diagonal line and little hooks at each end.)

Keep both pressed down together for a few seconds then release them. You're now in the clinical menu.

Use the Info Access button to go to the next item.

Use the on/off button and ramp button (like up/down buttons) to change settings.

The last item in the menu will be "ID." When you press the Info Access button one more time, that will exit you from the menu. Any settings you changed will be automatically saved.

Note -- When going through the menu, the next-to-last item will be the "pressure sensor offset" setting. Do not change that. That item will look like this, although the setting for your machine will probably be a different number:



dunnwes, check your Private Messages. The button at upper right of this page.

Bearded_One brought up something very important. Your main air hose has to have a pressure sensor tube running down through it to attach to the 420E.

Since the address I posted above requires searching for the manual, I'm adding a more precise one:
