the only thing I hate about this is that blood pressure has 2 "values". It's the only vital type that does. So I'm tempted to break out "Blood Measurements" into its own table that would have a "glucose", "systolic", and "diastolic" column. What I don't like about that, is that I will have a lot of null values in cases where only glucose is collected or only sys/dia is collected....
Any thoughts here that could help me make up my mind? TIA
