Goodnight 420E & 425

I understand that the Goodnight 420E is auto-adjusting. There is a sensor tube inside the hose. I was wondering if the 425 (bi-pap) also has the sensoer tube?

Interesting question. I didn't know, so I looked it up here:

cpaptalk interview with Puritan Bennett about the 425E bilevel

From the interview:

BillyJoe asks: Does the GoodKnight 425 device have a sensor line running down the hose?

The answer:
Yes, the patient tube for the GoodKnight 425 Bi-Level Device includes an internal pressure line, which provides pressure measurement at the mask, rather than the device, for a precise measurement and better comfort. This internal pressure line is also used for the GoodKnight 420G and 420S CPAP models.

I have a PB420E and a Remstar. I like the PB420E very much. It is light so it was no problem travelling in Scotland with it.
