 OB Basic Information

Enter the information required for OB diagnosis in the Patient Information window. The basic OB

information includes LMP (Last Menstrual Period) and Number of Fetuses.

Once LMP is entered, EDD (Estimated Delivery Date) and GA (Gestational Age) are entered

automatically. LMP is required for the calculation of values such as EDD and SD in obstetrics

measurement.

X

EDD (LMP) = LMP + 280 days

X

GA (LMP) = Current System Date - LMP

X

Enter Ovulation Date, and LMP will be automatically entered, followed by GA (LMP) and EDD

(LMP).

X

LMP = Ovul. Date -14

X

The physician may choose to override the LMP and manually enter the EDD into ‘Estab. Due

D a t e ’.

A maximum of four fetuses can be entered as Number of Fetuses. The default value is ‘1’. In the

case of twins, enter ‘2’.
