Failed to start command

2019-07-01T19:48:36Z

July 1st - Today we had a 'failed to start prep command' with no apparent cause (see attachment). The alarms were green and participant breathing was detected fine. We recalibrated and reverified the system anyway, but it didn't help. Therefore, we couldn't start prep. Has anyone else had this? (We've had this retry pop-up before with starting a sequence, but it always started eventually).

July 8th - Same thing happened today. Did not let us start prep but there were no warnings. Still investigating why.

Understanding Prep Stage

Can anyone point me towards the best materials/publications that I can read that will help me better understand the prep stage?

I understand that a good prep involves checking the end-tidal peaks are found adequately, and getting consistent breathing from your subject, but I would also like to better understand the algorithm used to arrive at the final baseline parameters, and wasn't sure where best to look for that. Typically, I'm seeing about +5mmHg increase from the first initially recorded end-tidal CO2 values (at start of prep) compared to the final targeted end-tidal CO2, e.g. 37mmHg at start of prep -> 42mmHg final target. I wondered if there were any recommendations for spotting whether the targeted baseline parameters were more - or less - plausible.

Thanks,
Rachael
