The OB Wheel Pro 7 is the most complete, powerful, and easiest-to-use tool for healthcare professionals providing prenatal care. In just ONE app there is 1) a gestational age calculator, 2) an ultrasound biometric calculator, 3) a fetal weight calculator, 4) a list of key weeks and trimesters, 5) an age-adjusted risk table for trisomy 21 and aneuploidy, 6) a BMI calculator, and NOW 7) an Apple Watch app is included with your purchase! The OB Wheel Pro 7 is a state-of-the-art gestational age calculator (also known as an obstetric or pregnancy wheel) that is used every day by doctors, obstetricians, midwives, nurses, and pregnant women. The OB Wheel Pro 7 is a professional tool that replaces the need for multiple apps and it greatly enhances the functionality of those worn-out cardboard wheels without compromise. The OB Wheel Pro 7 accurately determines the estimated delivery date (EDD), or due date, of a pregnancy based on the first day of a woman's last menstrual period (LMP), or from the date of conception, or from a known gestational age (GA) on a known date, e.g. from an ultrasound measurement, or from fetal biometry like Crown-Rump Length (CRL), Femur Length (FL), and BiParietal Diameter (BPD). Additionally, for appropriate gestational ages, The The OB Wheel Pro 7 estimates fetal weight and displays the number of days completed and remaining. The OB Wheel Pro 7, besides calculating GA from fetal ultrasound biometrics, enables clinicians to also calculate Estimated Fetal Weight (EFW) from FL, BPD, Head Circumference (HC), and Abdominal Circumference (AC) using the most appropriate published reference formula using the maximum and most appropriate parameters. Prenatal care providers know that there are key gestational ages where testing or interventions are needed. The OB Wheel Pro 7 lets providers see at a glance when these items should be scheduled.
