U.S. Version Report Page (cont’d)
EDD (LMP): Estimated delivery date computed from the
date of the first day of the Last Menstrual Period derived
from the edit field. The formula is:
EDD (LMP) = {LMP} + {40 weeks or 41 weeks as
selected in setup}
EDD (CUA or AUA): Estimated Date of Delivery
calculated from CUA or AUA as selected in the Setup
Menu. It is calculated using:
EDD (CUA or AUA) = {Exam date} – {CUA or AUA as
selected in setup} + {40 weeks or 41 weeks as selected
in setup}
All OB Calculations are calculated with average values.
For example, if two BPD values are available, the system
uses the average of those values. If it is desired to only
use a single measurement for calculation, deselect the
values in the Measurement Averaging Page that should
not be averaged.
Comments: Three lines of comments can be entered,
each line consisting of 54 alphanumeric characters.
Gestational Age Error Markers: Whenever three or
more gestational age (GA) measurements are included in
the CGA (the arithmetic mean of the included gestational
ages), an arrow may appear on the report page to mark
the GA which is farthest from the CGA. This arrow is
immediately to the right of the gestational age. This
makes it easy to spot the outlying measurement. If there
is a tie between two or more GAs for the outlying
measurement, no arrow will appear. When a hardcopy
print of the screen is made using
RECORD, the error
marker is temporarily erased and does not appear on the
print.
The US version formulas are given in a tabular form in
Table 13.
