OB Wheels

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.

It contains a calendar calculator to determine EDD (EDC) from LMP or from a sonogram report. The calendar calculator also provides gestational age (EGA) as of any date for a given EDD or LMP. Because the calculator works off the real calendar, it is accurate for leap years too.

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. 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. 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.

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. 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.

As an educator and clinician myself, I am grateful for feedback. Email me via the contact email at my website.

世界是否需要另一个OB轮到期日期计算器应用程序？当然！ OB轮结合了三个东西，临床医生需要获得所有必要的孕期保健的日期，并没有其他的应用程序都有这样的组合。

它包含一个日历计算器从LMP或声像报告确定EDD（EDC）。日历计算器还提供孕龄（EGA）的任何日期定EDD或LMP的。因为计算器的工作原理是从真正的日历，它是正确的闰年了。

那么对于大家谁错过了纸板OB轮，该应用程序包含一个你可以旋转，捏和缩放，一般玩就像一个普通的纸板轮。这是一个有点棘手学习如何种植两个手指并旋转它们，而不是捏和变焦，旋转与缩放。但车轮的作品，它是准确的，尤其是这样，因为你可以放大，以确保在小日期哈希线所在。

最后，应用笔记从组委会对一个会如何调和来自LMP和声像图到期日在一个单一的最终到达EDD最近委员的意见方案。据我所知，该方案是权威为基础，没有更好或更坏比其他方案，但我的实践，我的学生需要一个明确的计划，因此这个应用程序包括一个简单的参考。

作为一名教育工作者和临床医生自己，我很感激的反馈。通过在我的网站上的联系人电子邮件给我发电子邮件。
