Investigate empty bed garbage data

[jeremyestein]

Sympton is unmatched CSNs, but we think it's caused by getting garbage data through where there is no patient.

This could have consequences for our storage calculations if we're getting loads of useless HL7 data. We may have to go back and carefully delete stuff.

Claire to dig in the manual or ask Omar.

@thompson318 All waveform variables can send error messages. Generally any value < -32001 is an error. Please see attached for actual errors.

Does this account for all the messages with out a bed?

Thanks @clairejblack . I don't think I've seen values like that in the data I've looked at. I haven't looked at all the data though, and right now I can't think of a quick way to search through it for specific values like those.
