The formula to estimate the fundal height is:
\[ FH = GA \times 0.5 + 4 \]
Where:
Fundal height is the distance from the pubic bone to the top of the uterus measured in centimeters. It is used by healthcare providers during prenatal visits to assess fetal growth and development. The measurement is typically correlated with gestational age in weeks, and it can help identify potential issues with the pregnancy such as fetal growth restriction or macrosomia.
Let's assume the following value:
Using the formula to estimate the fundal height:
\[ FH = 30 \times 0.5 + 4 = 19 \text{ cm} \]
The estimated fundal height is 19 cm.
