Flow and pressure are provided as very high rate data; the rest is slow rate.
The event is reported as a 12 sec OA.
It starts with the pressure doing it's periodic thing swinging smoothly from 6.5 to 10.5 and flow is leading it by maybe 0.25 sec at most.
The flow reaches its peak normally, no anomaly noted, but the pressure does not follow it. Instead it swings up and reports a sharp peak at 11.4 cmH2O and slides down sharply. The pressure then makes another anomalous rise and falls to 6.4 cm where it stays for 16 sec. It ocillates 0.1cm around 6.4 for the last 10 sec then starts up the correct swing again going from 7.3 to 11.3 The pressure stopped responding before the flow stopped.
Meanwhile the flow swings normally until the pressure locks at 6.4 and then it goes to around zero where it stays for 16 sec. A blip on the flow data after 16 sec seems to instigate the pressure swing again.
3 sec later the OA event is reported.
There are no flow limits or snores reported. The ventilation, tidal volume,RR all show decrease at the slower data rate. Leaks are around zero.
So... Why does it look like the machine pressure instigated this event?
I see the oscillation on the pressure data half way through an event on most instances of flow stoppage including those less than 10 sec which don't get reported.
How does this compare to your events?
