SleepyHead vs ResScan?

I have been using ResScan since starting therapy and am pleased with the program. Does SleepyHead offer any advantage over ResScan? Should I bother to install SleepyHead in addition to ResScan? S9 SleepyHead users, what are your thoughts?

HI John, I used it a couple of times when he first made it available. It's a work in progress and I couldn't navigate it as easily as ResScan. I like the ability to add oximeter data into the same app for viewing, but when I tried it, it wasn't really there yet.. I'm not sure where it is now. It's great for PR users though, which I believe was the intent. I'll be watching to see what other Resmed users have to say.

I look at both. SleepyHead also has graphs for Respiratory Rate and Tidal Volume which I can't seem to get on the ResScan 3.14, if you're interested in those numbers. Currently, SleepyHead doesn't support printing of detailed daily data graphs. The ResScan "Reports" options are more comprehensive and look more professional as you can choose to include profile information and statistics along with summary and detailed graphs if you want. I think currently the only thing you can print in SleepyHead is the summary reports. I think they're both pretty good and SleepyHead is free so I'd suggest trying it out if you're interested. Nothing really to lose. If you don't like it, you can just uninstall it.

I haven't yet gotten into trying to monitor all the available stats, partly because I've been busy with other things the past few months, so I can't speak to which is best for doing that. The reason I use SleepyHead is that after I installed ResScan every time I tried to use it my computer would restart. I never could figure out what was causing it, and it was very frustrating. At least with SleepyHead I can review my sleep data over the past month or so, even I'm primarily checking my AHI and sleep times.

Bear in mind that SleepyHead is still only pre-beta, so it has quite a way to go before it is ready for daily use.

BTW, development has slowed down temporarily because Mark needed to have his appendix removed.

I haven't moved to 3.14 but I suspect the XML file changes are probably the same as in 3.12. After the xml file edits you can see the RR & TV graphs.

I think this is a little above my computer tech skill level. Where do you find the XML files? Are you saying that the data is there, but for some reason, ResScan chooses to block it so we can't see it?

I also noticed something kind of strange with last night's numbers in regards to leak rate numbers. On ResScan, I had a median score of 0.0, a 95th percentile of 3.6 and a maximum of 24.0. The strange thing was that on the actual detailed graph, when I hovered above the line on the graph, the highest point plotted was at 3.6. There wasn't anything close to 24.0 plotted on the graph. How could that be? The only thing I could think of was that I used the Swift FX nasal pillow mask last night and set it on Smart Start. When I took the mask off this morning, it blasted air out of the nose pillow for a second or two before shutting off. Might that have caused it to register 24.0?

Meanwhile on Sleepyhead, the numbers were minimum 0.0, Average of 0.35, 90% of 1.8 and maximum of 6.0 and the corresponding Sleepyhead graph did indicate a high reading of 6.0 as well. Shouldn't the maximum number for ResScan and Sleepyhead come out the same?

I have been using Sleepyhead exclusively for about a month. This was partly because I had to fire up a VM just to use Rescan and the whole process was incredibly slow. Then a month ago my VM stopped working so I started using Sleepyhead regularly. My VM is working again, but I haven't started using Rescan again, and I don't have any desire to.

Overall, the whole process of loading and having a quick glance at my data is so much faster and more convenient using Sleepyhead. There are a couple of minor usability improvements I would like, but generally I find it very intuitive. I have done things using it that I have no idea are even possible to do using ResScan.

Yes, the data is in the data files but for some unknown reason Resmed chooses to not make them visible by default.

xml files are in the same directory with the Resscan program files. You can edit them with a plain text editor but a special purpose editor makes it easier. It's really not too complicated and you can do it if you are reasonably well skilled in computer matters. If not, find someone to help you who is.

I've noticed in the past that Resscan summary data doesn't always seem to jibe with the raw data, or the graphs. Never took the time to pursue the issue in depth. I've seen some serious differences when I import the numbers from the raw data files into a spreadsheet and calculate the min, max, and 95% values. I suspect Sleepyhead is using calculations that mimic the spreadsheet calcs. No idea why they vary from Resscan. Math is math, I always thought.

There is one possible, or I think probable, explanation for the high leak rate in the summary data but not on the graph. The S9 writes data to the data files in whole minute increments beginning with the start time of the file. Any data after the whole minute is lost. There are several files that the data is recorded in, and they sometimes have significantly different start times. Those of us who have looked at that issue have no idea why it happens. So, if you take your mask off at the end of therapy you will have a huge leak. The S9 may have gotten that written to one of the data files but not to another. Let's say the leak occurs at xx7.6 minutes after the detail graph start time, and .3 minute before you turn off the machine, and the summary data start time is .2 minutes earlier. That means the detail graph would have been xx7.9 minutes long, but only xx7 minutes got recorded on the card. Since the summary data started recorded .2 minutes earlier than the detail, it would be at xx8.1 when you shut the machine off. The card would have xx8 minutes of data recorded, long enough to have caught the huge leak.

There are time differences between the various detail graphs sometimes also. I have had events show on the event graph after the flow graph stopped. It's all because of the differences in the recording start times, and the fact that all data ends on a whole minute increment after the start.

Hope this makes some sense. It can be kind of tough to visualize it, but think about it long and hard and it'll come clear.

I'll buy it...thanks for taking the time to respond in such detail!
