I would do this with a userform - see the basics at
http://www.gmayor.com/Userform.htm You can write the results or alternative texts based on the results to bookmarked locations, docvariables or content controls.
Take for example the part of the userform shown on that page to write a value to a bookmark i.e.
Code:
FillBM "bm1", Me.TextBox1.Text
If TextBox1 is your blood pressure field (it helps to use meaningful field names) then you could modify that to
Code:
If Me.TextBox1.Value > 160 Then
FillBM "bm1", "Elevated Blood Pressure"
End If
These are just simple examples. You could for example include error handling to ensure only numeric values are entered in the text box. You'll find code for that and other related things at
