To avoid misdiagnosis or harming
the patient outcome, start a new
patient information form before
starting a new patient exam and
performing calculations. Starting a
new patient information form
clears the previous patient's data.
The previous patient's data will be
combined with the current patient
if the form is not first cleared. See
"To create a new patient
information form"
To avoid incorrect calculations,
verify that the patient information,
date, and time settings are
accurate.
