Your doctor uses special types of equipment to conduct electronic fetal monitoring. The onset, nadir, and recovery of the deceleration usually coincide with the beginning, peak, and ending of the contraction, respectively.11 Early decelerations are nearly always benign and probably indicate head compression, which is a normal part of labor.15, Variable decelerations (Online Figure I), as the name implies, vary in terms of shape, depth, and timing in relationship to uterine contractions, but they are visually apparent, abrupt decreases in FHR.11 The decrease in FHR is at least 15 bpm and has a duration of at least 15 seconds to less than two minutes.11 Characteristics of variable decelerations include rapid descent and recovery, good baseline variability, and accelerations at the onset and at the end of the contraction (i.e., shoulders).11 When they are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions.11 Overall, variable decelerations are usually benign, and their physiologic basis is usually related to cord compression, with subsequent changes in peripheral vascular resistance or oxygenation.15 They occur especially in the second stage of labor, when cord compression is most common.15 Atypical variable decelerations may indicate fetal hypoxemia, with characteristic features that include late onset (in relation to contractions), loss of shoulders, and slow recovery.15. - When considering the effectiveness of Electronic Fetal Monitoring, it comes down to the experience and knowledge of the person identifying the tracings. Intrapartum fetal monitoring was developed in the 1960s to identify events that might result in hypoxic ischemic encephalopathy, cerebral palsy, or fetal death.

Structured intermittent auscultation is a technique that employs the systematic use of a Doppler assessment of fetal heart rate (FHR) during labor at defined timed intervals (Table 1).4 It is equivalent to continuous EFM in screening for fetal compromise in low-risk patients.2,3,5 Safety in using structured intermittent auscultation is based on a nurse-to-patient ratio of 1:1 and an established technique for intermittent auscultation for each institution.4 Continuous EFM should be used when there are abnormalities in structured intermittent auscultation or for high-risk patients (Table 2).4 An admission tracing of electronic FHR in low-risk pregnancy increases intervention without improved neonatal outcomes, and routine admission tracings should not be used to determine monitoring technique.6. Baseline is calculated as a mean of FHR segments that are the most horizontal, and also fluctuate the least. Whenever possible, they will implement measures to prevent an unfavorable outcome. Reviewed by Eugenia Tikhonovich, MD Obstetrician-Gynecologist, Medical Consultant Prolonged decelerations (Online Figures K and L) last longer than two minutes, but less than 10 minutes.11 They may be caused by a number of factors, including head compression (rapid fetal descent), cord compression, or uteroplacental insufficiency.
