In 2013, researchers proposed an algorithm for the management of category II fetal heart tracings. Fetal heart tracing is also useful for eliminating unnecessary treatments. External monitoring (unless noted differently), paper speed is 3cm/min. Itis called fetal tachycardia when it is greater than 180 BPM. Subtle, shallow late decelerations can be difficult to visualize, but can be detected by holding a straight edge along the baseline. Abnormal fetal acidbase status cannot be ruled out. Variability describes fluctuations in the baseline FHR, whether in terms of frequency, amplitude, or magnitude. Its carbon-14 (614C)\left({ }_{6}^{14} \mathrm{C}\right)(614C) activity is measured to be 60.0% of that in a fresh sample of wood from the same region.

Additionally, an Apgar score of less than 7 at five minutes, low cord arterial pH (less than 7.20), and neonatal and maternal hospital stays greater than three days were reduced.22, Tocolytic agents such as terbutaline (formerly Brethine) may be used to transiently stop contractions, with the understanding that administration of these agents improved FHR tracings compared with untreated control groups, but there were no improvements in neonatal outcomes.23 A recent study showed a significant effect of maternal oxygen on increasing fetal oxygen in abnormal FHR patterns.24. Remember to check out the additional resources below, including advice from our seasoned JFAC young physicians and links to ACOG wellness and clinical resources. Internally monitoring involves a thin wire and electrode placed through the cervix and attached to the baby's scalp. Initiate oxygen at 6 to 10 L per minute, 5. The physiology behind late deceleration is uteroplacental insufficiency.16,17 Transient late deceleration patterns may be seen with maternal hypotension or uterine hyperstimulation. [10] The first step involves identifying whether there are accelerations or moderate variability. The main goal is to identify fetuses who are prone to injuries stemming from hypoxia (or a lack of oxygen for fetal tissues).
