Due Date Calculator, Gestational Age, Estimated Fetal Weight and 10+ ObGyn tools

Obstetric Calculator (also known as Obstetrical Wheel) will help to determine gestational age in weeks and days as well as estimated due date using last menstrual period, ultrasound report, ovulation/IVF and other methods.

In addition, there are 10+ handy ObGyn tools in the application.

The full list of available tools and scales:

- Estimated due date (EDD) & Gestational Age by First Day of Last Menstrual Period (LMP)

- EDD & GA by Ultrasound Report

- EDD & GA by Conception Date

- EDD & GA by Fetal Movements

- EDD & GA from Given Date

- GA & LMP from Estimated Delivery Date

- GA by Crown-Rump Length (CRL)

- GA by Fetal Biometry

- Estimated Fetal Weight by Mother's Biometry

- Bishop Score (Quick Cervix Assessment)

- Probability of Successful Vaginal Birth after Cesarean Section (VBAC/TOLAC)

- Breast Cancer Risk Estimation (Gail Model)

- Cervical Cancer Risk Estimation (ASCCP 2020)

Each tool is accompanied by instructions ("i" in the upper right corner).

This app was designed for educational use by health care providers in the field of Obstetrics & Gynecology.

The Obstetric Calculator, a vital tool for healthcare professionals, simplifies complex calculations related to pregnancy and childbirth, offering quick and accurate results for crucial parameters. Its primary function is to determine the Estimated Date of Delivery (EDD), commonly referred to as the due date. This calculation, based on the first day of the last menstrual period (LMP), provides a benchmark for tracking fetal development and planning for labor and delivery. The standard method, Naegele's Rule, adds seven days to the LMP, subtracts three months, and then adjusts the year if necessary. The calculator automates this process, eliminating potential human error and providing a reliable EDD.

Beyond the EDD calculation, the Obstetric Calculator often includes functionality for determining gestational age, the time elapsed since the first day of the LMP. This information is essential for assessing fetal growth and development and scheduling appropriate prenatal tests and screenings. The calculator accurately tracks gestational age in weeks and days, providing a clear picture of the pregnancy's progression.

Furthermore, many Obstetric Calculators incorporate features for calculating the estimated fetal weight (EFW). This estimation, based on ultrasound measurements of fetal parameters such as head circumference, abdominal circumference, and femur length, helps assess fetal growth and identify potential complications like intrauterine growth restriction (IUGR) or macrosomia (large for gestational age). The calculator utilizes established formulas to provide an EFW, aiding healthcare providers in making informed decisions regarding fetal well-being.

Another valuable feature often included is the calculation of the fundal height, the distance from the pubic bone to the top of the uterus. This measurement, taken during physical examinations, correlates with gestational age and provides another indicator of fetal growth. The calculator allows for quick comparison of the measured fundal height with the expected value for the given gestational age, alerting clinicians to potential discrepancies.

Some advanced Obstetric Calculators offer additional functionalities, such as calculating the Body Mass Index (BMI) before pregnancy and recommending appropriate weight gain during pregnancy based on pre-pregnancy BMI. This feature helps manage gestational weight gain and promotes maternal and fetal health. Furthermore, some calculators provide information on expected changes during each trimester, offering valuable educational resources for expectant parents.

The user interface of Obstetric Calculators is designed for ease of use, with clear input fields for the required data, typically the LMP or gestational age. The results are displayed prominently and clearly, facilitating quick interpretation. The digital format eliminates the need for manual calculations, saving time and reducing the risk of errors.

The accuracy and reliability of the Obstetric Calculator are paramount. The calculations are based on established medical formulas and guidelines, ensuring that the results are consistent with current obstetric practice. This precision contributes to improved patient care and informed decision-making.

In conclusion, the Obstetric Calculator serves as an invaluable tool for healthcare professionals involved in prenatal care. Its ability to accurately calculate the EDD, gestational age, estimated fetal weight, and fundal height, along with other potential features, simplifies complex calculations, saves time, and improves the quality of care provided to expectant mothers. Its user-friendly interface and reliance on established medical principles make it an essential resource for managing pregnancies and ensuring positive outcomes for both mother and baby. The readily available information provided by the calculator empowers healthcare providers to make informed decisions and provide optimal care throughout the pregnancy journey. The convenience and accuracy of the Obstetric Calculator contribute to a more efficient and effective approach to prenatal care, ultimately benefiting both patients and healthcare professionals.
