[select name="respiration" value="less than 30 breaths per minute=0|greater than/equal to 30 breaths per minute=1"] <-- Respiratory rate
[select name="BP" value="systolic greater than/equal to 90 and diastolic greater than 60=0|systolic less than 90 or diastolic less than/equal to 60=1"] <-- Blood pressure
