The recording of Vital Signs is accessed by a function key. The particular function key depends on how your system is set up. See the "Settings" tab and then the "Function Keys" tab. I have the "Vitals" on F5 for my own system. Inside a consult, press F5. You can type in the vitals, press the "Calc BMI" button, and then either insert the results into the current encounter, and save into the database, or just save into the database. Synapse EMR saves these results as numerical values which can be accessed in the Patients/Results/Numerical Results tab. As numerical results they can be graphed and reported upon. Note that if you are entering data in lbs and ins, you have to use the <enter> key on those fields. This then puts the data into the metric fields for the BMI calculation to work.
