RE: Philips-Respironics "DreamStation" - new CPAP series on the way
PajamaGame, I am glad you like your new device. May you have many good years of use from it and sleep well and vigorously.
I had clearly stated it in my first post and subsequent posts that it was a first impression based on a rather over-quick look in a noisy environment, I described the design flaws as I saw it based on that impression, including the possible noise problem from the redesign of the air intake, which was confirmed by another poster who now was using the device, thus showing that my first impression had some accuracy in it (and why not? I work with medical devices all day long, so I do know what I am looking at) and while I am glad it does not exhibit such noise at a fixed pressure of 8 cm, it does at higher pressures, and that may present a problem for users who need higher pressures or use variable pressures. If it is only intended to be near silent at 8 cm of air, then it is not a useful device, is it? It should then have a warning on it - do not exceed so many cm of air or noise values will increase uncomfortably. I might point out the its predecessor has no such problem at 15 cm of air.
For those who are used to the PRS 50/60, the removal of the tank is more complicated in the Dreamstation, although not by a lot, but enough to take a bit of getting used to. I found the addition of a lid over the CF card to be a hindrance, and years and years of experience working with medical devices tells me this may be a point of failure if subjected to constant use. Plastic breaks, that is a rule.
Nowhere did I use the word junk or imply that it was junk.
I did not like the new colouration, and that of course is a subject of taste, and I am pretty sure it was clear to any reader that such a thing was a matter of taste - again, I said it was impression. As for that "certain device", I really don't think I have ever described it on any thread, so I don't think it is obvious to people who don't have to deal with disgustingly and embarrassing biological aspects of medicine on the course of their daily work. It was also a bit of a medical joke, if you had a sense of humour for it.
When I get a Dreamstation in my hands for extensive testing (January, when they become available in Switzerland) I will make a more thorough report. In the meantime, I can only go on my first impressions, which is what I reported on and clearly stated as being. And my first impression was that it was a cosmetic move for the sake of cosmetic moves, adding little new to the already successful and efficient design of the PRS line, and this was of interest to those who use the PRS now and would like to know how it differs - if you have experience of the PRS, I invite you to please make the comparison between the two, so that people here may benefit from your knowledge. As it is, my impression is the redesign is strictly a marketing move to counter the A10. People I know in Philips confirm this sentiment, and the data sheets I have received do not indicate any immense improvements in the algorithms that would necessitate a redesign of the physical system. I am not a fan of redesign for redesign's sake, particularly when the original design was efficient and successful - clunky, yes, unattractive, yes, but efficient. Putting go-faster stripes on a scalpel does not make it cut any better. Again, I spoke of my first impressions, and when I get to test one, I will be able to report better on it, but yes, I will compare it to the PRS, because that is the device it is replacing and PRS users should be informed if it is a step up a step sideways or just more of the same. An informed user is a good user.
One more thing, PG, you ARE new to CPAP, I am not, nor are many people here - perhaps you might trust that experience of a wide range of devices counts for something.
As for your implication that I have a problem with CE, why would I have a problem with CE? Conformité Européene is a mandatory marking system for medical and consumer devices, and I can recall no time I have spoken against it here or anywhere. Philips is not a leader in CE - CE is a mandatory mark they and all manufacturers have to have, showing that it passes safety standards. The leader in CE is the organisation that administers it, not the manufacturers. Why you should even bring it up is beyond me - I never have, and it is a most unusual region to discuss, particularly as I get the impression you are not European, and CE is strictly for Europe. North America and other region have heir own certification authorities. One is neither a fan nor not a fan of such things - they are the regulatory hoops one has to jump through if one puts a product on the market.
