I got my new Phillips Respironics Dreamstation Auto CPAP recently. Of course I tried it out at nap time.
No Bueno – the pressure was only 5cm. I am prescribed 10cm of pressure. I thought it was the Ramp feature, so I turned it off (Ramp Time zero). Still it was stuck on 5cm of pressure when it ran. The ramp feature has 3 choices for initial pressure – 4, 4.5 and 5cm. This was a bit confusing, but I determined that the Ramp function was Off and I should be getting whatever was prescribed for me. I called my provider. They checked the machine and re-downloaded the settings. They confirmed that the machine was set for 10cm. They also told me that the pressure shown on the screen didn’t matter – it was the Ramp initial pressure. I read in the User Guide that this was not correct. The Pressure shown (when it’s running) is in fact the working Therapy pressure. It was still at 5cm and not changing. I headed to the Internet and found out how to go into the Clinician Settings. I confirmed that the machine was set for 10cm. I tried to understand what each setting did.
I played with the Auto CPAP settings and was able to get it to start at whatever pressure I wanted. I noticed that Auto CPAP switches the EZ-Start function Off. I turned off Auto CPAP and left EZ-Start Off. The Therapy pressure was now correct (at 10cm for me). What does EZ-Start do you may ask.
Eventually came across this –
EZ-Start
Reduces the therapy pressure for the first few days of operation and the device automatically gradually increases this setting until the prescription therapy
pressure is reached. On/Off
And after some further searching -
If the EZ-Start is engaged, it will start at 50% of the prescribed pressure (but the minimum pressure must at least be 5cmH20). Now every time that person can successfully sleep more than 4 hours a night with their CPAP at ½ pressure…the CPAP machine will on the next night start at 1cmH20 higher. It will continue to do so until the prescription setting is achieved. Previously, doctors would have the medical equipment company increase the pressure by 1cmH20 every week. Now the machine will do it automatically. Fantastic feature.
Fantastic indeed! You are air-starved for in my case at least 5 days (well maybe 8 or 9cm would be OK). It was set to initially give only one half of my prescribed pressure.
The answer –
Switch Off the EZ-Start Function
Lesson learned –
Your provider probably has no clue. Don’t simply trust what they say. Figure it out yourself. Get a copy of the Clinician Settings Guide. Understand what your machine is doing.
Mini Review -
The new machine is now working very well. It’s very quiet and I like the heated hose. The Air Filtering is much improved. It has a lot of Wiz Bang features – built-in cellular modem and Bluetooth. Be aware that your provider can get the machine to automatically Phone Home which allows them to change settings and monitor compliance. I just needed to make sure that my provider won’t try to reset the EZ-Start ever.
I used a nasal pillow for many years (Swift II), but I decided to try the newer ResMed AirFit P10. It’s smaller, lighter, and quieter. The headgear is an improvement and much more comfortable. The fit was good. I had no leakage right from the start. It’s a clear winner.
I purchased a new SoClean unit. Hopefully the improved filtering on the Dreamstation and the Ozone disinfection of the SoClean will also be a positive experience for me. The SoClean machine is pretty noisy. It buzzes quite loudly during the 7 minute cleaning cycle and then runs silently for the 2 hour purge cycle. Hopefully it works better than it sounds. I can’t believe an engineer couldn’t get it any quieter. There is a slight hint of Ozone when you use the CPAP after cleaning, but I didn’t find it to be too bad. I’m used to a hint of detergent after washing these parts so it’s just a new “fragrance”.
I hope this helps.
Best Regards,
