ResScan-aligning 30 sec graph w 8 hour graph

Thanks Jay,

I wasn't clear about the sliders. I only mentioned them as an afterthought. After selecting the time of an event in the top graph and noticing the bottom red vertical line wasn't aligning well, I would resort to moving the sliders. Even then, I couldn't align the vertical lines representing the two time slices as I thought they should be.

This problem has persisted over a number of downloads and installs of various versions. Wish I could figure what is causing my problem.

Has anyone had any luck communicating directly with ResMed about the ResScan software? Aren't they changing their stance somewhat on "patient use of ResScan"?

Oldern, it's a long shot, but have you checked the difference in time setting between your computer and your machine? Since you are gathering data via cable and I think I read ResScan treats some forms of data differently (high resolution vs detailed), I suppose it's possible some data may be referenced to computer time and some to machine time. I doubt this is the case, but hey, it's easy to check.

I just installed ver 4.2 of ResScan and am having the same problem with alignment of the two graphs in detailed view. In the bottom graph the red line should be somewhere near of the middle of the two vertical lines in the top graph. You can see it is not that way.

I haven't had time to check the suggestion about possible difference between my computer and my machine. I do remember setting the time to agree once or twice and there is the thing about daylight savings time. I will look.

Any other suggestions

Here is the reply I received from ResMed Rep when I asked them why the time labels were different in the top graph (Navigational pane, I think) and the detailed graph below.

Thank you for contacting ResMed.

Can you contact your provider to assist with your question, we don’t support rescan for patients are using. We only give support ResScan to our providers. We recommend patients use our Sleepseeker software at http://wakeuptosleep.com/ Sorry for the inconvenience.

If you have any additional questions please feel free to call our Technical Support Department at 800-424-0737 option 6 then option 2.

Regards

This is about what I expected from ResMed. I haven't called their tech support but I probably will Monday. If anyone finds anything of value at the website the Rep referred to, I'd be interested in knowing. I'm thinking of emailing back and asking him to contact my DME, his provider and customer.

Brief review when the top graph shows a normal eight hour graph and the lower graph shows a 30 min slice of time:

I pinpoint a particular event in the top graph which, say, occurred at 5:00 Am. The particular point and event will be centered near the red line in the lower graph. However, the time depicted in the label for that graph will show, say, 5:20 AM. This has occurred over several upgrade versions of ResScan. Among other things, it makes me wonder which is the correct time of the event.

Probably the easiest way to figure out which time scale is closest to the recorded data is to pick a specific graph point that will be easy to find and look at the EDF file with EDF Browser and see what time it shows with it.

Late response to Jay: I downloaded data this AM and the time on the machine corresponded identically with the time shown on my computer. Thanks for suggestion.

idamtnboy, I googled the browser you mentioned on the internet but don't have time to check it out now. I'll try to give it a look later. One question comes to mind, though. Can I be sure the correct time as shown by the browser for a particular time point on one or the other graphs would persist across any data points selected? Knowing which graph depicts the correct time would help, of course. However, it is still a p I t a to have to deal with the apparent incorrect time labels in one or both of the graph.

I sent another email to ResMed asking them to contact my DME if they didn't want to deal with a patient. Hopefully, my DME will get some time to follow up on his end and perhaps between the two of them-well who knows?

Anyway . . . ?

Are you familiar with the different EDF data files? Each one carries its own time data. If not, I'll explain the details but it's been awhile since I've looked at them so I'll have to refresh my familiarity.

No, I'm not familiar with those files.

Well, this is interesting. I turned on my machine last night at about 1:12 or 1:13 Am according to my clock in the bedroom. Looking at ResScan for last night, with the navigation graph set for 8 hours and the detailed graph set for 30 minutes, I see that the detailed graph shows a start time of about 1:11 AM. Yet the navigation graph, the top graph, shows a start time of about 00:35 AM.

So, the detailed graph appears to be more accurate . . . hmmm.

On the detailed graph set for 8 hours, the start time appears to be closer to that shown on the navigation chart.

Odern,
I'm not sure if you're till watching, but if you are, I thought you might be interested in this, a condition similar to that you were experiencing. I noticed that while using ResScan 4.2.0.8.5438, the first 30 minutes of all my pressure graphs were missing. I don't use ramp or anything that would cause this, the first 30 minutes of pressure just were not being represented graphically. Other than that, the remainder of the graph was correct with pressure changes represented correctly at the appropriate times, in line with the other graphs. Not a big deal, nothing much happens in the first 30 minutes, anyway. I don't know how long this problems has existed, probably since installing 4.2. Interestingly, looking back at my posts on page one of this thread, I see the first 30 minutes of pressure was missing and I didn't notice it then.
This morning I installed ResScan ver 4.3.0.7081 and it works fine, the first 30 minutes of all pressure graphs have been restored.
