What is OB Wheels? OB Wheels is a pregnancy care app that combines three essential features for clinicians. It includes a calendar calculator to determine EDD (EDC) from LMP or sonogram report, a cardboard OB wheel that can be rotated, pinched, and zoomed, and the most recent committee opinion scheme from ACOG on reconciling due dates from LMP and sonograms.
1. To my knowledge, the scheme is authority-based and no better or worse than other schemes, but my practice and my learners need a single clear scheme, so this app includes one for easy reference.
2. Does the world need another OB-wheel-due-date-calculator app? You bet! OB Wheels combines three things that clinicians need to derive all the dates necessary in pregnancy care, and no other app has this combination.
3. Finally, the app notes the most recent committee opinion scheme from ACOG on how one might reconcile due dates from LMP and sonograms to arrive at a single final EDD.
4. Then for all of you who miss your cardboard OB wheel, the app contains one which you can rotate, pinch and zoom, and generally play with just like a regular cardboard wheel.
5. But the wheel works and it is accurate, especially so because you can zoom in to be sure where the little date hash lines lie.
6. Because the calculator works off the real calendar, it is accurate for leap years too.
7. It contains a calendar calculator to determine EDD (EDC) from LMP or from a sonogram report.
8. The calendar calculator also provides gestational age (EGA) as of any date for a given EDD or LMP.
9. It's a little tricky to learn how to plant two fingers and rotate them rather than pinch-and-zoom to get rotation versus resizing.
10. As an educator and clinician myself, I am grateful for feedback.
