These are events that are in the PRS1 files but which OSCAR doesn't know how to present:
- An F0V6 event with duration that looks like PB or LL but doesn't appear on any official reports
- The Auto-CPAP pressure to use at the beginning of a session
- A report of the snores detected at each pressure/EPAP/IPAP
- Apnea alarms on F3V6
Rather than bury the understanding in commented-out sections of the parser, these events
will now be parsed and added to the internal event stream, which allows them to be dumped
to YAML. Whenever OSCAR eventually supports these data, the importer will have ready
access to them.
Again, no change to external behavior.
This only affects the parser at this point, and the importer has been updated so that
there is no externally visible change to the imported data.
Eventually we'll need to figure out how to display the two differing kinds of
pressures, at which point we'll need to fix the importer to use the right channels,
instead of the inconsistent treatment now.
The next step will be to split parsing from mode interpretation, so that
we can at least accurately identify all of PRS1's modes. Then we can
work on mapping that to OSCAR's notion of modes, which probably then needs
to be augmented.
Also fix an issue with initializing the model names, since QObject::tr
won't work at global initialization time. And series detection needs
the untranslated names anyway.
Also clean up brick detection.
The official names don't yet appear anywhere, since there's a question
of how to juggle manufacturer, series, and model name in the various
places they're (inconsistently) displayed.
Series is also used to pick the machine icon.
This fixes the mask pressure graph as well as many of the events.
There are still some issues with presentation: some of the events are
being drawn at the wrong time, and certain events and statistics
don't really behave the way they're displayed.
Also several events have yet to be encountered in sample data.
Pressure settings are now properly being found and decoded, but there are lots
of unknown fields to figure out.
It turns out it uses the same humidifier setting encoding as F0V6, and the first
several slices seem to be the same. But pressure encodings are different, with
a gain of 0.125 instead of 0.1, presumably to allow for a maximum pressure of
30 cmH2O.
