8.2.3. Obstetrics Measurements

Obstetric measurements are used to calculate the GA (Gestation Age), EDD (Estimated Delivery Date)
and EFW (Estimated Fetus Weight).
The Obstetric package supports measurements and reports on up to four fetuses. If you know the
number of fetuses at the start of the exam then you can enter this in the Patient page (see section 4.4).
When the number of fetuses is known the system adjusts the user interface to optimize for that
number. If no information is entered about the number of fetuses the system will assume there is one.
