The nurse is caring for a client during the second stage of labor. On assessment, the nurse notes a loss of variability. The initial nursing action is to pivot the client onto her side and provide oxygen by face mask at eight to ten Litre/min.
Short-term variability is the transition in the Fetal Heart Rate (FHR) near the baseline in the range of five to ten beats per minute (BPM). Long-term variability is a comparatively slow shift in heart rate and includes a frequency of 3-10 cycles per minute and a range of ten to twenty-five beats per minute (BPM).
