Issues with CMS50E pulse oximeter - new and different issues

[coolguyclay]

I can read waveform data while it's in USB mode

Yeah, the waveform data wouldn't be too useful as a history. I was mainly just asking from a tech standpoint - pretty clever to get the live data. Does the software give an interface for that or is your python script accessing the USB signal directly somehow? Send me a PM if you don't mind sharing about it. The live waveform has me interested but I don't want to hijack this thread : )

I'm sending myself an email so I can post the code from the other computer, I keep forgetting.

I'm just using a serial ruby library... did I say Python, I mean Ruby. I did have to install the drivers for the USB serial adapter for that cable, but it was easy to find once I saw what manufacturer made the windows drivers.

That unit looks awkward to wear while sleeping. I've had pretty good luck with this one. I had a problem with downloading not working several months after purchase. Formosa Medical replaced it for free. I reviewed it.


My only gripe is that my ASV clock is slow by 21 minutes. So, it takes a bit of calculation to see if a particular event in my ASV report is related to a signal in pulse or oxygen saturation.

Hi Bill,
I bought the the PC68b in order to have a better understanding of my central sleep apnea.
I received it this morning, but unfortunately I am not able to install the soft.

The file data2 is corrupted. I believe the CD has a defect.

I am wondering if someone could send this particular file by email (it is arround 9.5 MB) !


Thanks in advance

It's not so much that I've forgotten as I've been trying to clean it up for public consumption.

When I'm done it'll live here. http://github.com/ohammersmith/spo2read

I'm gonna spend some time on it today, but no promises.

I could send you the file(s) I have ... one of which was actually downloaded from a link in another post here... but I'm not sure it would do any good. None of the versions I installed actually ever worked. Hence I wrote my own.

Did anyone ever get ahold of this script?
I'd love to get the CMS-50E working on my mac, but the github repo seems to contain nearly-empty files.


Thanks,
Jesse

Are you able to capture the (live) waveform data, or just data points?

I can read waveform data while it's in USB mode, but in record mode it only records data points.

I could probably hack something up to read the serial port and leave it in USB mode all night. Not sure it's relevant, though.. what would you use a historical HR waveform for, that you couldn't get from 1 Hz HR signal?

What is the raw data format for the stored data upload?

thanks.

[This Works]

1. With your finger in or out of the unit, long press to get to the menu.
2. The cursor should be on "Record Off". Long press to change to "Record On"
3. Short press moves cursor to "Exit". Long press to exit.

At this point the unit is recording. The flashing yellow dot is showing whether your finger is in or not. It will start gathering data when your finger is in the machine. If you take your finger out it will wait till you insert finger again.

Next morning...

4. To stop recording. Long press till menu appears.
5. Cursor should be on "Record On". Long press to change to "Record Off".
6. Short press moves cursor to "Exit". Long press to exit.

Ok now to download!

7. Start up the Green heart SPO2.
8. If not already connect the USB cable. (at this stage I'm assuming the unit is NOT connected to the cable)
9. Connect unit to cable. Do NOT turn on.
10. In program, click on the "New Session" button. (magnifying glass).
11. Enter details, click OK
12. Program should say "Waiting for data".
13. Long press on unit till menu appears. At this point the program should say "Receiving Data".
14. Enjoy the data!

The data will stay on the unit till you "Record On" again. You can't lose the data till you press "Record On" again. That's the only way to wipe the memory. Between steps 13 and 14. When at the Settings Menu with arrow pointing to Record Off, make a short press to start "Receiving Data". Don't do a long press as this will start recording and erase previous data.
