OB Wheel (Pregnancy calculator)

The OB Wheel app is newly available as a Progressive Web App.

https://obwheel.quartertone.net

----------------------------------------

Multi-function pregnancy calculator. Created by a board-certified ObGyn.

Calculate dates of pregnancy:

-Last menstrual period (LMP)

-Estimated date of conception

-Weeks gestational age (WGA)

-WGA obtained by ultrasound

-Dating by IVF Embryo transfer

-Calculate gestation by Crown-Rump length

-Estimated due date (EDC)

-"Time Machine" mode can calculate "How many weeks will patient be on xxxx date?" and "When will patient be xx weeks gestation?"

Features still present, but no longer supported:

-Store multiple patients for easy retrieval

-Adjust length of cycle and luteal phase

-Full Help pages

-Include extra notes in patient data

Please note: This app may be used for personal tracking purposes, but it is primarily meant to be a clinical tool for professional healthcare workers.

**************************

***IMPORTANT NOTE***

**************************

This app calculates exactly 280 days (40 weeks) from LMP to EDC, and accordingly for any date in between. Please note that the paper/plastic wheels used by obstetricians or ultrasound technicians are inherently inaccurate. Different pregnancy wheels may vary by as much as 3 or 4 days. Please keep this in mind when comparing the values obtained here to those given in clinics/hospitals.

----------------------------------------

多功能怀孕计算器。由董事会认证的ObGyn创建。

计算怀孕日期：

-月经期末（LMP）

-预计怀孕日期

-周胎龄（WGA）

-通过超声波获得的WGA

-通过IVF胚胎移植约会

-通过冠臀长度计算妊娠

-预计截止日期（EDC）

-“时间机器”模式可以计算“患者在xxxx日期有几周？”和“患者何时怀孕xx周？”

功能仍然存在，但不再受支持：

-存储多个患者以便于检索

-调整周期的长度和黄体期

-完整的帮助页面

-在患者数据中包括额外注释

请注意：此应用程序可能用于个人跟踪目的，但主要是为了成为专业医护人员的临床工具。

***重要的提示***

**************************

这个应用程式会精确计算从LMP到EDC的280天（40周），并据此计算介于两者之间的任何日期。请注意，产科医生或超声技术人员使用的纸/塑料轮本质上是不正确的。不同的怀孕轮可能相差多达3或4天。将此处获得的值与诊所/医院给出的值进行比较时，请记住这一点。
