This tool is designed for educational purposes and is adapted from the SOGC 2020 Fetal Health Surveillance (FHS) guidelines. It can make mistakes. Clinical judgment is paramount.
Not a Diagnostic Tool: This is NOT a clinical diagnostic tool or a medical device. It is an educational tool only.
User Responsibility: The user assumes all responsibility for clinical interpretation, diagnosis, and management plans.
Logic Limitations: Algorithmic logic may not capture all clinical nuances (e.g., maternal pulse interference, signal loss, or evolving clinical pictures).
No Liability: The creator explicitly disclaims all liability for any damages, medical errors, or adverse outcomes resulting from the use of this tool.
Institutional Protocol: This tool does not replace institutional policy or professional clinical training.
By clicking "I Understand," you acknowledge these limitations and assume full responsibility for the clinical application of any output.
Promptly take all necessary steps to resolve maternal-fetal heart rate coincidence and reassess the fetal status once resolved:
Place oximeter on maternal finger / Manually assess maternal pulse rate
Reposition external fetal monitor
Consider Internal Fetal Scalp Electrode (FSE)
If coincidence continues with FSE in place, consider a real-time bedside ultrasound to verify fetal heart rate and distinguish from maternal heart rate
What is the fetal heart rate baseline (rounded to the nearest 5bpm)?
Tachycardia Duration (>160bpm)?
Why is the baseline Indeterminate?
FHR Baseline Trend
Baseline Variability
Minimal or Absent Variability Duration?
Marked Variability Duration?
Accelerations
Are there any decelerations?
Select all that apply.
⚠️ Caution:
A baseline abnormality was selected. A variable deceleration in the presence of a baseline abnormality (Tachycardia, Bradycardia, Minimal or Absent Variability) is classified as a Complicated Variable. Ensure the correct selection is made based on the full clinical picture and appropriate deceleration identification.
