Sleepyhead data rebuild

[mdemers800]

The last week or so of my Sleepyhead data seems to be corrupted. Each day I copy a summary of the data to an excel spreadsheet and what is now coming up in the daily summary no longer matches the spreadsheet for the last 5 days or so. I assume the correct first step is to use the rebuild CPAP data menu item. However, I load oximetry data daily also. Does anyone know the impact of a rebuild to that data? I had loaded that data daily to sleepyhead from dated files on my computer after having uploaded tom my computer from my Contec CMS50F using the SPO2 Assistant s/w program.

One more question.... I had lost some of my early oximetry data in Sleepyhead, it is just not there anymore. I have all the data in dated files on my computer. Is there a way to reload to some of these older days? I appear to be on SleepyHead v1.0.0-beta-2 and in that user interface, I cannot find a way to select a date for oximetry data load. So far, I have just been loading it daily after my CPAP data import and then synching the time stamp.

Thanks,

Michael

I have never understood why people obsess over historical data. The only important thing is about having everything setup to provide excellent therapy tonight ... and the next night ... and the next night ....

I agree...I have no Idea why people are obsessed with saving years of data...Why would you care what your AHI was a year ago? What's important is what your AHI is now.

Data trends are useful. This is what I do for a living, I run Data Management functions at large corporations. I am still experimenting with different masks, taping for mouth leaks, use of a cervical collar, APAP vs CPAP, pressure levels, EPR, etc. For example, my scores were bad last night because I forgot to put on my collar. Last time they were that bad was before I started using the collar. So I do find use in data trends. I now know that not using the collar causes a least 3 points difference in my AHI, (in OA and Hypopneas). When I use the collar, at the same pressures, I am at almost zero for those and my scores are mostly centrals. I learned this by experimenting and looking at the data. I also used the data to see I trended much better on CPAP than APAP, so I am pretty much CPAP exclusively now.

So, what is your AHI and leak level when you remember to set things up properly?

I am still going back and forth between amaraview mask and P10. With the P10, I have to do mouth taping as I sputter out air leakage if I do not.

Leakage on the P10 with tape is close to 0 for average and about the 95% level is around 1-2. The AmaraView leakage is about around 3 or 4 average and about 6-8 at the 95%.

My AHI averages about 2 with everything right, almost all of that is centrals. My CPAP pressure is 8.6. When I don't use the cervical collar, my AHI is 5+ and I get about 2+ on OA and the same on Hypopneas. The most significant thing to me is that that my centrals are always 10-20 seconds. My OA can be 30-40 seconds, when I get them. I am not sure why, but this cervical collar makes a huge difference for me.

They may not be centrals. It is common for us to reflexively hold our breathe when we move or otherwise change positions. My stats usually show a few short centrals; I go into IGNORE mode over them.

I am not sure why, but this cervical collar makes a huge difference for me.

1. It holds the airway in the best position (chin away from chest) for airway patency.
2. It keeps the lower mandible from dropping and falling back slightly. The further forward the lower mandible is, the more room for the back of the tongue to clear the airway.

The cervical collar is also a charm for me. Pressure requirements are lower, AHI is lower and there is less mouth breathing.
