What is the minimum recommended tracing duration for electronic fetal monitoring (EFM)?

• A. 10 minutes
• B. 20 minutes
• C. 30 minutes
• D. 45 minutes

Answer: (B)

The minimum recommended tracing duration for electronic fetal monitoring (EFM) is 20 minutes. This duration is crucial because it allows sufficient time to obtain a baseline fetal heart rate, assess its variability, and identify any decelerations or accelerations that may indicate fetal distress or a healthy fetal status. Monitoring for only a shorter period, such as 10 minutes, may not provide an accurate representation of the fetal heart rate patterns, leading to potential misinterpretation. A longer duration, like 30 or 45 minutes, while beneficial for observing trends over time, exceeds the minimum recommendation and may not be necessary in all clinical scenarios. Therefore, adopting the 20-minute standard ensures a balance between efficiency in monitoring and the need for adequate data to inform immediate clinical decisions regarding fetal wellbeing.
