An example:
row_id 24288398,24288390 and 24288389 in table chartevents are all for the same patient.
Itemid 224687 (row_id 24288398) shows the minute volume at charttime 2101-09-12 17:00:00
Itemid 220293 (row_id 24288390) shows the Minute Volume Alarm - High at charttime 2101-09-12 17:00:00 (same charttime)
Itemid 220292 (row_id 24288389) shows the Minute Volume Alarm - Low at charttime (2101-09-12 17:00:00) (same charttime).
I thought that the alarm events occur then the special item values (here minute volume) undergoes or overgoes some border but how could it be that all three events (minute volume, Minute volume alarm - high and minute volume alarm - low) could appear at the same time?
Maybe my understanding of how the alarm events work is just wrong. So what is the interpretation of the alarm events (here for example Minute volume alarm - high and minute volume alarm - low)?
