OB Calculation

 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 Gestations.

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

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

X GA(LMP) = Current System Date - LMP

Regardless of LMP, enter the EDD with a physician’s opinion in

P is not available,

when Estab. Due Date is modied, LMP is automatically calculated and the “C” mark is displayed next to

the LMP information.

A maximum of four fetuses can be entered in the

Gestations

menu. The default value is ‘1’. In the case

of twins, enter ‘2’.
