Importing CMS 50D Plus oximeter data into SleepyHead

This page summarizes one method to import CMS 50D+ Oximeter data into Sleepyhead software using the CMS USB cord.

Prerequisites:

• The SpO2 software must be installed on your computer with the appropriate user rights.
• Sleepyhead software must be installed with the appropriate user rights.

Note: USB serial importing directly from the device and live view are not covered here.

Starting/Stopping the meter for the Oximeter study

1. Ensure your finger is positioned properly in the device and the device secured to your finger such that it will remain in place during the study. Do not block access to the meters button with tape or other material.
2. Press and hold the meters button until the menu is displayed. Scroll through the menu items by pressing the meters button once to advance to the next item. Select the “Record On” / “Record Off” function by scrolling until the arrow points to the function.
3. To start the meter logging data press and hold the meters button until the function changes from “Record Off” to “Record On”. Scroll to the exit function. Press and hold the meters button until the menu closes. Note: Selecting “Record On” will overwrite previously recorded data.
4. Starting the CPAP machine at the same time the meter is started will allow for easy synchronization of the CPAP/Oximeter data when importing into Sleepyhead.
5. You should now see a flashing yellow dot indicating that the unit is now recording.
6. To stop the meter logging data press and hold the meters button until the function changes from “Record On” to “Record Off”. Note: Do not put the meter back into the “Record On” mode until you have saved the data otherwise it will be overwritten and you will lose the data.

Saving the CMS 50D Plus Study data to your computer

1. Ensure that the provided SpO2 software has been installed on your computer.
2. Ensure the meter in no longer recording data (step 6 above).
3. Connect the meter to your computer via the provided USB cord.
4. Press and hold the meters button until the menu is displayed and verify that it is in the “Record Off” mode (step 6 above).
5. Start the SpO2 software by clicking on the green "SpO2 Review" icon (not the red "SpO2" Icon that is used to receive real time data from the meter).
6. Click the “New Session” Icon on the software interface.
7. Enter a name for the data file. Enter any optional patient data you would like and then click “ok”.
8. Device connected, waiting for data will be displayed followed by "Receiving Data".

Importing and syncing the Oximeter data into Sleepyhead

1. Start Sleepyhead and import your CPAP data as usual.
2. Determine the time the CPAP was started by zooming to the maximum detail and noting the start time (e.g. 4/3/2012 22:41:46).
3. Click on the Oximetry tab (or icon).
4. Click on “_Open SpO./R File” located in the lower right corner of the sleepyhead user interface.
5. Navigate to the storage location the SpO2 software stored the file and select it.
6. Sleepyhead will then import the data. Look at the timestamp on the lower left side of the interface. Change the time to match the time you noted from the CPAP in step 2 above.
7. Click on the “Save File” icon located in the lower right corner of the sleepyhead user interface.
8. The data will be saved and the Sleepyhead Oximetry window will display “No Data”. This is normal.
9. Open the Sleepyhead daily tab and you should see the Oximetry data charted at the bottom of the page. There should also be a summary on the details tab.
