Your numbers on initial CPAP are very similar to my own. In the majority of people the AHI will improve with time usually within 2 months. It is great that you are sleeping better. In the meantime you can reduce your number of centrals by lowering or preferably turning off the EPR. However make sure...

If I were mouth breathing, would'nt it show up on the leak data........... hmmmmm, so if both pillows were blocked almost completly from being nasal clog or on skin then it would not show any leak data except the normal leak line that the pilairo has... Very interesting, I would have had to breath ...

Archangle, excellent point about the constant leak rates putting any mechanical blockage beyond the vent ports. Not familiar with the Pilairo but I wonder if the pillows could displace and impact into the skin. It is pretty extreme and sudden for nasal blockage. Thank goodness for mouth breathing! Ian

Ian, I thought about that and I am just not positive that did not happen... it could have, but what if it did not?? crazzy to think that but maybe... If it did not, sorry to say but you would not be here. The tidal volumes reported during those two hours are less than the physiological dead space o...

Could be a blockage of the flow sensor. However my first thought on this is that your tubing or mask blocked off. It happened suddenly and corrected suddenly. Is it possible that the tubing kinked somewhere? The machine reactions and Sleepyhead do look to be working correctly. I presume you would ha...

Am nose breather except when I clog up which could be part. Of the high pressure leaks I'm getting now. Thanks again. Missed this first time around. Nasal obstruction can be a cause of poor response to ASV treatment of central events and result in higher ASV pressures. With a full face mask, this o...

Most recently I have developed large leaks, where the machine high pressure limits and I leak a lot. Is the machine actually over breathing for me and forcing me into Chayne-Stokes to compensate? Hi Arkis There could be an element of this certainly. As Palerider says the main problem at the moment ...

JDSL thanks for the information about obstructing the airway, I will have to use this in future. Just a couple of points regarding all the above, firstly the 960 disables the BPM automatically when the PS Max is set to 0 for APAP or CPAP mode. When breath holding (without physically obstructing the ...

As part of an experiment to provide some data to Jedimark concerning SleepyHead, I did an experiment this morning. I tried to set up my Respironics ASV machine to be in straight BiPap mode. Here are the parameters: http://i1100.photobucket.com/albums/g416/jds74/Respironics%20Data/2014-08-08TherapyD...

For completeness sake, I'm going to need someone to record a short CPAP (& APAP if the mode is present) sessions on an ASV machine, and send me the resulting .001 and .002 files to see if it reuses the same code (0x04) for Pressure Pulse. Here is the short test session for the 960 running in APAP/C...

How does one get the 960 into either APAP or CPAP modes? APAP mode can be entered on the 960 by adjusting the PS Max to zero in the clinicians menu (APAP mode does not exist on the 950). CPAP mode can be entered by setting the PS MAX to zero and, in addition, setting the EPAP Max and EPAP Min to be...

Pressure pulses are only generated by the PR 960 if it is operated in APAP or CPAP modes (which it almost never is). In ASV mode it generates timed breaths only. From a quick experiment tonight (breath holding), I can confirm that 'pressure pulses' do show as red squares on Encore Pro and that they ...

Jedimark is amazing. Sleepyhead/Encore comparison done and I can confirm the results as per my previous post.

Photonic Just In case you have not heard from Jedimark, who must be incredibly busy! The red dots are 'timed breaths' and correspond to the purple dots on Encore Pro. These are where your next breath has been slower to start than the machine expected and it puts in a breath for you. So these are 'ma...

The pressure graphs are calculated and updated every 2 minutes. During that two minutes you would have say 25 breaths and each breath would have a different IPAP as the machine changes the pressure on a breath by breath basis. The graphs are the maximum IPAP, mean IPAP and minimum IPAP during those ...
