Some Personal Observations on New System One from Respironics
I've been trying out the new System One from Philips-Respironics this past week, and wanted to capture my observations in a thread so that others considering the device have the benefit of some color commentary:
I have the System One Auto-Adjusting CPAP. I am making the transition after years of using the M Series Auto-Adjusting CPAP with A-Flex from Respironics. Unlike a few months back when I tried out the ResMed S8 Autoset II with EPR Auto-Adjusting CPAP, the transition to the System One was a smooth one. It felt familiar and identical therapeutically to my M Series. When I tried the ResMed, it was a very different feeling, and I awoke in the morning feeling cloudy and unrested. I attribute the difference to the different algorithms ResMed and Respironics employ. Going from one manufacturer's machine to the other is a lot more jarring than "marrying up" to the latest device in a given manufacturer's line.
The device looks a lot less intimidating out of the box than do most flow generators. That's because there aren't many buttons on the device -- the user interface has migrated to an iPhone-like dial that lets a user scroll on an LCD screen through various user options.
For those who want to tinker with their own therapy, and adjust their own settings, suffice it to say there is a "secret handshake" that gets you into the clinician's menu. I don't necessarily encourage or discourage this sort of self-therapy -- I leave it up to adults to make intelligent decisions on their own as to what to do here.
The humidifier is one of the biggest advancements over the M Series in my view. No matter how high I cranked it up, i didn't get "rain-out." It also seems to be much more economical in its use of the distilled water I added into the humidifier chamber. I only filled it up ~25%, and it wasn't much lower than that in the morning. I found that the M Series consumed a lot more water, even at low humidifier settings. Furthermore, the humidifier chamber is designed to be spill-proof, which is nice for those of us who have transported a humidifier full of water only to find the water spill into the innards of the machine and cause problems.
Here's the biggest rub about this machine: while it's fully data-capable, and has an SD card that captures every breath you take and the efficacy of your therapy, there is no path for the patient to obtain last night's data on his/her own. Respironics needs to put out patient software for this device, as it has for its predecessor, the M Series. Why keep patient data behind lock and key?
I'll report more as things occur to me, but wanted to report my initial thoughts now.

to stop glasses steaming up when entering bue s in cold weather conditions you take them off and after you enter the bus you put them back on to prevent condensation. the condensation is cause by a hot and a cold front and this what rainout is
rMike said:Got word back from the Respironics rep I'm in touch with, with the following answers:
1. RE HUMIDIFICATION PROBLEM: Occasionally you may get mask condensation from the warm air you are exhaling through the mask. It is very difficult to control this. You shouldn't get rain out in the tubing though.
2. RE PATIENT ORIENTED SOFTWARE FOR SYSTEM ONE; Just asked that the other day. They are working on it with no expected release date.
3. RE SYSTEM ONE BIPAP RELEASE: System 1 BiPAP and System 1 BiPAP Auto are both out as of about a week or so.
Jan said:Does anyone know if the end user software is out yet...and whether the System One Bipap is out or when it might be coming to market?
Mike, also wondering if you figured out the humidification problem you talked about in your post above.
Thanks
Jan

Mike have you experimented with the "Split night mode" available in "Auto-CPAP mode"? Will the S9 have this option? If it does not not I will support this machine as the best auto-PAP on the market. For those of you that do not know this option allows you to be in straight CPAP mode for a set time and then switch to auto mode at the end of that time. We tend to have more breathing events in the last 1/3 of our sleep. We also get the majority of our rem sleep during this time.

I am also using the system one machine. So far i like it very much. I have had no rainout with machine, I was constantly fighting rainout before. My DME took the sd card out of the machine and said I did not need it. Said phone line was all I needed. Do I need the sd card? She said if I wanted any readings to call the sleep lab.

I haven't experimented with the split night mode yet, but wondering whether it would be advisable in my case. I have a pretty tight pressure range of 10-12 and am always in auto-PAP mode. Would changing to the split night mode do anything for me?

Split night mode is an auto-option. It will only work while in auto mode. Your 90th percentile pressure is more representitive of your NREM sleep which is predominate in the first 2/3 of your night. 75% of your sleep is NREM (in most cases). Your higher pressures are going to represent your REM sleep (in most cases). We see most of our REM in the last 1/3 of our night. Split night mode allows you to lock in a pressure for a specific amount of time. At the end of said time the machine switches to a true auto mode. This mode acknowledges the progressive nature of apnea as it relates to our sleep architecture. This would put even more limits to the auto algorithm. It keeps your pressures low, and allows them to go high when needed. No more fighting with the pressure changes caused by sleep onset.

sounds like another good tool to have in the arsenal, but it seems to assume a lot of knowledge on the part of the patient or clinician, as the case may be, as to when in the night REM sleep occurs -- and doesn't this vary by person and by night?

The knowledge was needed for the discovery of the imprtance of this option. the abiltiy to aplly it comes from being able to read your PAP data. Yes sleep varies from person to person. The properties of the sleep architecture vary only by the interruptions. The healthy sleep brought on by effective PAP therapy is very predictible.
Studies show that in most cases apnea is worse during REM. My experiecnes tell me the same. Most of the PAP data that I have seen support this. REM sleep occurs about every 90 minutes in healthy sleep. Stage REM starts out in short burst that progressively get longer with each cycle. Check your numbers. I would be willing to bet that for most on PAP therapy the events follow this pattern. As would the pressure changes with any auto. Most of the data that i have seen show a small grouping of events within 2 hours of going to bed. then a larger grouping between 4 and 7 when REM is abundant.

My resmed rescan downloads support these numbers. My apneas are concentrated at these times.

Thank you Mary Z. Your support on this is most appreciated. Most people become REM specific on PAP therapy. This means that the majority, if not all, of your events will be during REM while on PAP. this is due to the fact that respiratory function by nature is irregular in REM.

Mr. Lauren,
Thank you for your interest in the Philips Respironics products. The patient software has not been released yet. We have been told it is to be released this quarter.
Thank you,

It is? Is it available to us "lowly" patients anywhere? ;)
