CMS50 Events

Does anyone know what constitutes an event flag in the Spo2 review software?

Is it just indicating a sudden drop / climb of some number of points?
Dropping below a certain threshold?

What Oximeter events flags would you like to eventually see in SleepyHead? (they will have to be seperate to the main flags, as time scales don't match)

Also, what oximeter report data other than the min/max/avg?

I am already working on time-below-threshold (%) code.

there are two types of events here, desats and pulse:

Start the SpO2 program and select a session for review.
Then notice the tools icon in the lower left of the screen. Click on it.
The screen that opens gives the definitions of events for the SpO2 program and the ability to change the values to suit your analytical needs.

Thankyou...

Desaturation Event: drop in SpO2 by at least 4% for a minimum duration of 10 seconds.
Pulse Event: Change in rate by at least 6 bpm for a mnimum duration of 8 seconds..

So that's fully adjustable in SpO2 review software?

I wonder if that's a drop/change from a running average, or the previous value?

I never fiddled around to answer that question. However you can. SpO2 saves a session file in the Program Files folder under the sub folder Data. The data file with the one second samples is a .CSV file. This file is a simple text file containing pairs of SpO2 values and Pulse values.

So ... You can edit the file to create any sequence you like to see how the program handles the data.
For example, edit in a sequence of value pairs such as:
90,62
90,63
90,64
90,65
90,66
90,67
etc,
Then put in a new series
90,55
etc,
Then run SpO2 Review and see what is reported.
