Another area of interest is the use of computer analysis for key components of the fetal tracing,29 or decision analysis for the interpretation of the EFM tracing.30 These have not been demonstrated to improve clinical outcomes.29,30 Fetal pulse oximetry was developed to continuously monitor fetal oxygenation during labor by using an internal monitor, requiring rupture of membranes.31 Trials have not demonstrated a reduction in cesarean delivery rates or interventions with the use of fetal pulse oximetry.31. Rhythm abnormalities of the fetus. Adequate documentation is necessary, and many institutions are now employing flow sheets (e.g., partograms), clinical pathways, or FHR tracing archival processes (in electronic records). This web game uses NICHD terminology to identify tracing elements and categorize EFM tracings. Strongly predictive of normal acid-base status at the time of observation. Accelerations (A). 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. A wooden artifact is found in an ancient tomb. American Pregnancy Association. The fetal heart rate tracing shows ALL of the following: Baseline FHR 110-160 BPM, moderate FHR variability, accelerations may be present or absent, no late or variable decelerations, may have early decelerations. -*considered significantly non-reassuring, esp when repetitive and associated w decreased variability*, Repetitive late decelerations are defined as, occurring *after 50%+ of contractions in a 20 min* period, *uteroplacental insufficiency*, as a result of eitehr decreased uterine perfusion or decreased placental function From time to time the app may be updated with revised content.

Late decelerations (Online Figure J) are visually apparent, usually symmetric, and have the characteristic feature of onset of the deceleration after the onset of the uterine contraction.11 The timing of the deceleration is delayed, with the nadir of the deceleration occurring after the peak of the contraction.11 The onset, nadir, and recovery of the deceleration usually occur after the beginning, peak, and ending of the contraction, respectively. The information is reviewed in a stepwise fashion to guide the learner through the evaluation of this commonly-used diagnostic procedure and discusses different clinical scenarios and their impact on patient care.
