measurements (mm or cm), ratios (%) or fetal weight (g).
The Fetal growth curve graph shows the following
information for the selected measurement:
• The normal growth curve
• The standard deviations or relevant percentiles
• The gestational age of the fetus, using patient data
(vertical dotted line)
• Using the current ultrasound measurement data, where
the fetus is on the growth curve
From the OB graphs screen, the user can enter relevant
information in the Fetus position and Placenta fields.
The system provides calculations (e.g. estimated fetal weight)
and charts based on published scientific literature. The
selection of the appropriate chart and clinical interpretation of
calculations and charts are the sole responsibility of the user.
The user must consider contraindications for the use of a
calculation or chart as described in the scientific literature. The
diagnosis, decision for further examinations and medical
treatment must be performed by qualified personnel following
good clinical practice.
