What is a characteristic feature of fetal hypoxia in relation to FHR?

• A. Increased variability
• B. No change in FHR
• C. Decreased variability
• D. Steady baseline

Answer: (C)

Decreased variability is a characteristic feature of fetal hypoxia when monitoring fetal heart rate (FHR). In healthy fetuses, variability in the FHR reflects the ability of the fetal autonomic nervous system to respond to stimuli and maintain homeostasis. When a fetus experiences hypoxia, the oxygen supply is compromised, leading to a diminished response from the nervous system. This results in decreased variability in the heart rate patterns observed. In clinical practice, recognizing decreased variability is crucial as it often indicates that the fetus is under stress, possibly due to inadequate oxygenation. It helps clinicians make informed decisions regarding further intervention or monitoring of the pregnancy. In contrast, increased variability or a steady baseline would suggest that the fetus is not currently experiencing hypoxia, and therefore, decreased variability serves as an important alarm signal in fetal monitoring.
