This is simply the best Obstetrics calculator in the market. This application is designed and written by a practicing OBGYN and tested clinically. 1) Rapid Gestational Age Calculator: having 8 date pickers enable a practitioner to enter the due day in less than 3 taps. Each date picker is a month apart from one another. One can easily scroll down to the desired month and then press to select the day of the month to complete the input. Each of the date picker is numerically pre-assigned each time the user signs into the program. 2) Fetal Weight Percentile: weight percentile from 2 sources enhances clinical decision making. Percentile information is calculated from employing error functions and z scores with the primary focus of being the most precise at the 10th percentile. This percentile level is an important cut-off for deciding the course of action. In addition, a weight projection at 39 weeks is revealed. This projection provides improved obstetrical understanding of percentile and can help providers and families to better analyze their situations. 3) Final Estimated Due Day: physicians or assistants enter the first day of last menstrual period, date of ultrasound and gestational age to establish the final estimated due day. This is the calculation in accordance with the guidelines of ACOG. Each clinical picture and comprehension shall be more pivotal than ACOG guidelines but this approximation can provide an impetus for discussion. 4) Weight Conversion: unit conversion from grams to pounds and vice versa is completed in this part of the program. Ultrasound almost always generate an estimate in grams. Many struggle to understand weight in grams while others face the challenge of locating a calculator swiftly. This section yields the answer and saves time for more crucial or critical conversations in other areas. Disclaimer This application provides information that is meant to be educational.
