Outline Intro Determining the gestational age of a fetus is very important for the well being of the fetus throughout the pregnancy. Women are encouraged to get prenatl care. With a pregnancy wheel, clinicans use the tool to determine the woman’s due date, fetus’s approximate weight, appropriate testing, and more. What is a pregnancy wheel? According to Naegele’s rule, a typical pregnancy is 280 days long, or 40 weeks, therefore, a device was needed to help clinicians know what was happening to the pregnany woman and developing fetus week to week. The pregnancy wheel is a device that has helped the perinatal healthcare provider in a variety of ways.

How does it work? The device is a small plastic wheel with a calendar among the outer circular area. Inside the big circular device is a smaller circle to align the date with the last menstrual period and date of delivery for a uaul 40 week pregancy. Markers placed seven “days” apart to display and label the number of weeks between the last menstrual period and the delivery date. Ideally, this is 40 weeks. The little marks between the weeks indicate days, therefore, if the marker showed 30 weeks and two little “days” marked, the pregnancy would be 30 2/7 days…show more content…
