Well at least it worked for me so far....I have seen a ton of ppl on ehre say that it wont work with it...this was my reply to another post on here...In case this helps anyone...

I just wanted to comment I have the PB 420S with the sensor line and i use the comfortcurve. My sleep doc's office rigged mine up for me all the did was use the 6 ft hose with the sensor and used a little connector piece to connect the comfortcurve tubing and my machine worked fine with it pressure stayed the same and all (we were concerned about that at first) and my machine still records data just fine. I just had it read for the first time and I was having 20+ episodes an hr during sleep study and now with the 420 and the comfortcurve I had only 26 episodes in 26 days so they said average of one per night but the doc was very pleased with this. So yes it can be done! Ohh and I was the first person to try the comfortcurve in their office...

Except now you have 12 feet of hose instead of 6. 6 is plenty for me to cope with. And I travel a lot by air, so that would be another 6 feet of hose to fit in the travel CPAP bag.

Rumor is that cpap.com is soon to come out with a sensor line kit. It'll allow you to use any hose length you can procure with any mask, you just hook the sensor near the mask.

At first i was liekno way I can deal with 12 ft of hose but now I have gotten so used to it not to mention way more room f or me to turn over and be comfy with that I struggle to use just 6 ft of hose now inmy bed cause like last night I was stopped up from allergies and tried to use my ff mask adn well with only 6 ft of hose I ended up pulling the cpap machine and humidifier off the beside table...I mean I know this wont work for everyone but I just wanted ppl to know just because you have that machine you can still try the comfortcurve if you wanted to...

You did right, Heather.

You brings up an interestign new issue: once you get used to a 12 ft. hose - how do you handle the 6 ft?
Sleep is such a thing of habit!

GoodKnight 420S CPAP
Key Product Information

Manufacturer: Puritan Bennett
Part Number: YGK420S-NA

"This is a standard CPAP machine which delivers one level of pressure during inhalation and exhalation."

That's great that a connector between the Comfort Curve's 5 or 6 foot air hose and your PB 420S's 6 foot air hose (with sensor line) seems to work well for you, Heather.

I wonder if that additional 5 feet length with no sensor hose could adversely affect what your machine actually can sense happening? If something in a person's breathing happens, but the machine can't "see" it, that "happening" isn't going to appear on the data. That might not be as crucial for your 420S, since it's a straight cpap; but, I wonder if so much "non sensor" additional length could possibly skew the data results the doctor sees? Perhaps leaving out some events on the data because the machine couldn't see them through the extra length of non-sensor tube hose. I have no idea. If you're feeling good, though, then the connected hoses probably are fine for you and your machine, no matter if the data might (or might not) be a little off.

However, that could be a more important question for people using a PB 420E autopap. If an autopap cannot accurately sense from the air flow what is truly happening with a person's breathing, the autopap's actions might be detrimental to good treatment. It might respond to erroneous breathing info with too much pressure or too little.

Since everything an autopap does and everything it tallies up (or leaves out of) the data depends on what the autoap is sensing in the first place, the autopap's data could be even more "off" than the data from a straight cpap machine.

Of course, all my musings are only IF an extra 5 feet of non-sensor line hose would affect what either machine can "sense".

Before 420E autopap users try connecting two hoses that way, it might be a good idea to check with someone technical at PB. Find out just how long the "un-sensored" distance can be, between mask and machine, and still feed accurate info to the 420E autopap.

Gosh, we miss -SWS, don't we?
