OVERVIEW

Obstetric Calc is a sophisticated application designed specifically for healthcare professionals in obstetrics, midwifery, and maternal-fetal medicine.

KEY FEATURES
1. Advanced Dating & EDD Calculator
· LMP (Naegele's Rule): Standard 280-day calculation from last menstrual period
· Ovulation Dating: Precise dating based on known ovulation date (266 days)
· ART/IUI/Transfer Dating: Specialized calculations for assisted reproductive technology
· Fetal Biometry (Hadlock Formula): Ultrasound-based dating using BPD, HC, AC, and FL measurements

Each method automatically calculates:

· Estimated Due Date (EDD)
· Current Gestational Age in days and weeks
· Trimester classification (First, Second, Third)
· Clinical alerts for pre-term, term, and post-term pregnancies

2. Comprehensive Clinical Metrics
BMI & Gestational Weight Gain
· Pre-pregnancy BMI calculation with IOM/ACOG category classification
· Automatic weight status categorization (Underweight, Normal, Overweight, Obese)
· Evidence-based weight gain recommendations

Mean Arterial Pressure (MAP)
· Rapid MAP calculation for pre-eclampsia risk screening
· Simple systolic/diastolic input with instant results
· Essential for hypertensive disorder assessment

HCG Doubling Time
· Early pregnancy viability assessment
· Calculate doubling time over any specified interval
· Critical for ectopic pregnancy and miscarriage risk evaluation
3. Gestational Diabetes Screening (OGTT)
· 75g OGTT interpretation based on WHO/ACOG criteria
· Evaluates fasting, 1-hour, and 2-hour glucose values
· Clear diagnostic output:

4. Fetal Assessment Tools
Estimated Fetal Weight (Hadlock Formula)
· Comprehensive EFW calculation using four biometric parameters
· Utilizes the validated Hadlock regression formula
· Output in both kilograms and grams for clinical precision

Bishop Score (Simplified)
· Labor induction readiness assessment
· Evaluates dilation, effacement, and station
· Score range 0-9 with intuitive classification

5. Advanced Risk Assessment
Pre-eclampsia Risk (sFlt-1/PlGF Ratio)
· Evidence-based ratio interpretation
Pregnancy of Unknown Location (PUL) Risk
· M4 (Multiple of Median) risk assessment
· Combines HCG and progesterone values
· Provides actionable risk stratification for ectopic pregnancy

6. Real-Time Labor Monitoring Dashboard
A unique, interactive feature for active labor management:

Contraction Tracking
· Start/stop timing for individual contractions
· Automatic frequency calculation
· Real-time interval monitoring
Cervical Dilation Monitoring
· Manual entry of dilation readings
· Visual progression tracking
· Phase identification (e.g., transition phase at ≥8cm)

Fetal Heart Rate Monitoring
· BPM entry and tracking
· Automatic bradycardia/tachycardia alerts (<110 or >160 bpm)
· Historical logging with timestamps

USER EXPERIENCE FEATURES
