Thoroughly revised for its third edition, this volume is a practical guide to the physiology, instrumentation, applications, and interpretation of fetal heart rate monitoring. A major portion of the book presents actual cases and monitoring strips that illustrate abnormalities such as fetal distress, fetal distress in prematurity, and central nervous system dysfunction. This edition features a new chapter on fetal pulse oximetry using a non-invasive electrode placed on the fetus' cheek during labor. Case examples include strips from the cheek electrode and the traditional scalp electrode. This edition also includes information on new drugs used during labor that affect fetal heart rate.
