Category I FHR includes all of the following: baseline: 110-160 bpm The probe sends your babys heart sounds to a computer and shows FHR patterns. meconium stained amniotic fluid is present in 10-20% of births, and most neonates don't experience issues. FHR baseline usually ranges from 120-160 beats per minute (bpm); however, with fetal decelerations, the heart rate usually drops about 40bpm below baseline. The FHR normally exhibits variability, with an average change of 6 to 25 bpm of the baseline rate, and is linked to the fetal central nervous system. Continuous EFM increased cesarean delivery rates overall (NNH = 20) and instrumental vaginal births (NNH = 33).

During a term antepartum NST (non-stress test), you notice several variable decelerations that decrease at least 15 bpm and last at least 15 secs long. This mobile app covers the following topics: Basics of reading and evaluating fetal heart rate tracings, including baseline determination and variability; the evaluation and biological background of various types of accelerations and decelerations; and a set with case examples for practicing the interpretation of FHR tracings. Fetal heart rate (FHR) may change as they respond to different conditions in your uterus. The different catagories of FHR tracings and their clinical meanings are discussed. Nadir of the deceleration = peak of the contraction. This fetal heart rate deceleration quiz will help you learn how to differentiate between early decelerations, late decelerations, and variable decelerations. Periodic changes in FHR, as they relate to uterine contractions, are decelerations that are classified as recurrent if they occur with 50 percent or more of contractions in a 20-minute period, and intermittent if they occur with less than 50 percent of contractions.11 The decrease in FHR is calculated from the onset to the nadir of the deceleration.
