treatment pressure higher than the setting pressure
03-29-2016, 10:18 PM
In my experience this is caused by rainout. There are many threads on this topic. In short, you will need to control the moisture in your tube. First, get a climate line hose. Set it to auto. Get a snuggle hose cover as well. Read the other threads for suggestions. Read Resmeds web page on controlling rainout. These are the methods I used to tame the machine going to 10 with a pressure max setting well below that.
See also today's discussion on thread - water in tube. It applies to your situation.
past the maximum pressure setting?
Please note: I understand that rainout might be mistaken for snoring or a flow limitation and lead to a pressure increase. But we're not talking about a run of the mill pressure increase here: We're talking about the machine increasing the pressure past the maximum pressure setting, and that's very unusual.
In other words, since the max pressure setting is 8 cm, why would the machine decide that it needs to deliver 10cm?
To debby2242: Any chance you show us the detailed data for 3/28/2016? By the detailed data, I mean the the graphs for the flow rate, pressure, and leak rate? You can do this in either ResScan (if you downloaded "all" the data) or SH. I believe that SH 0.9-8 works with the AirSense 10 AutoSets.

It's a CPAP which doesn't collect data I believe.

The Autoset collects full data.
And, RobySue -- a very good question. I'm thinking it's not the machine; but the reporting software.

Is your attachment from ResScan software?
Is there a possibility that your pressure has been changed remotely by your DME? I've heard of this happening.
The APAP should not rise above the max setting.
Double check your pressure settings in the CLINICIAL menu.

The reason I'd like to see the detailed data is to figure out whether the "max" value is some kind of a "freak peak" or whether the machine actually raised the pressure that high in response to some kind of event or snoring or flow limitation.
If the machine is indeed raising the pressure above the max setting, then my guess is that it's a faulty machine. If this were me, I'd be taking it back to the DME and asking them what the heck is going on. And demanding that the machine be replaced under warranty.

She should verify the settings in the Clinicial menu, as DME's have been known to change settings remotely.
Also, the ResScan software may not be giving reliable data.
If you have verified all stats, then I would asked for the machine to be exchanged.

This is a newbie question. The "pressure" being talked about here is a "setpoint" pressure and not a "detected" pressure, right? Just want to make sure I understand what I'm seeing in the data from my machine. The pressure graph I see from my data is either spiky or a series of ramps, not an organic-looking graph like what I see with flowrate.
