Creating a Profile

If you have migrated your data from a previous SleepyHead installation, Oscar will automatically migrate your SleepyHead profile(s) as well. (See Migrating data). Otherwise when you first open up OSCAR, you will be asked to create a profile.

Your data is associated with a profile and you may have multiple profiles and each may have multiple CPAPS associated with it. However if you have more than one machine (especially if they are different brands), it is recommended that each machine be in its own profile.

To read more about creating and maintaining profiles, see [OSCAR Profile Page]

Importing Data into OSCAR the FIRST time

Once the profile is finished and saved, OSCAR will display a welcome page that looks like this:


You will see that the options to select statistics, overview or daily view are greyed out until you have loaded (imported) some data into OSCAR.

Put the SD card into the SD slot if you have not already done that. If your computer does not have an SD slot, you will need to buy a generic SD card reader and put the SD card in that.

WARNING: It's wise to make sure the card is locked if you are using a Mac or a Windows 8.1 or Windows 10 machine since these operating systems will write hidden files to unlocked cards. And the ResMed S9 machines will reject SD cards with any extra files written on them. See Secure Digital (SD) memory card for instructions on locking a card.

If you are about to import on a Chrome OS system, please read and follow these different instructions Mounting your SD Card under Chrome OS and then return here.

Once the card has been mounted to the computer system, you still need to import the data into OSCAR. There are three different ways to Import the data:

  1. The Import Icons on the main window and the sidebar. Click either of these and it starts the import process.
  2. The Import Data under the File sub-menu. Select this from the standard File menu in the usual way for your system and it starts the import process.
  3. The keyboard shortcut. On a Windows machine you can simply press the F2 key and that will start the import process.

The Import Data menu item and the Import Icons are arrowed in the screen shot below.

With your SD card is in the SD slot or card reader, once you click on Import Data, you will get a small pop up dialog box that looks this:

Click "Yes", and the data should load. After the initial data import, OSCAR should display your data in a screen that shows the Statistical Data. It looks like this:

Clicking on the Daily tab in the OSCAR window brings up the Detailed Daily Data for the last day of data:


Clicking on the Overview tab in the OSCAR window brings up the bar graph data, which provides a summary of the last week, two weeks etc right out to "everything". Note that selecting Everything can take several minutes to generate the chart if you have several years of data.:

Importing Data into OSCAR AFTER the first time

Each time you want to import data into OSCAR you go through the same basic process, except you don't have to create the profile:

Step 1. Open OSCAR

OSCAR will bring up a list of profiles for you to chose from. For most people, there will only be one name on the profile. Highlight the desired profile and press the Select User button. The data for that profile will load into OSCAR and the Statistics page should load.

Step 2. Make sure the SD card is in the SD slot or card reader

It's wise to make sure the card is locked if you are using a Mac or a Windows 8.1 (or later) machine since these operating systems will write hidden files to unlocked cards. And the ResMed S9 machines will reject SD cards with any extra files written on them.

You will need to have the card in the Write Enabled (unlocked) condition while it is in the S9 and Write Protected (locked) prior to inserting it into your computer. Also, some of the newer low-cost card readers do not have the micro-switch installed in the unit. This means that even if you have it write-protected, it may not stop it from having the system files written by the PC.

To be safe you may wish to download and use the following script. It will turn off(or back on) this feature on your PC. Prevent SysVol Info Write

Step 3. Import the Data

Once OSCAR loads the data for the selected Profile and the SD card is mounted, you can import the (new) data by either pressing the Import icon, using the File menu to select Import Data, or the keyboard shortcut---pressing the F2 key. The Import dialog box will appear and if you are importing from the After the first data importation, you can import the data regardless of which data view you are looking at. If you import data while in the Daily Data view, the Daily Data will jump to the last day of imported data after the data is successfully imported.

Additional Notes

1) The process for importing the data is easy once you get used to it.

2) Remember to properly unmount the SD card from your computer before removing it from the SD slot or card reader. You unmount the SD card the same way you unmount a flash drive or an SD card from a digital camera.

3) Remember to put the card back into your CPAP machine. This is particularly true for ResMed users: All the detailed data is written directly to the SD card, and if there is no SD card, that data is lost. And OSCAR will report that there is no data for the night. (ResScan will be able to report on the summary data that is stored in the S9's memory and then written to the card when it is inserted into the machine).
