WebSome tracings remained nonreactive (three of 15), and some tracings remained reactive (four of 15) at both assessments. None of the tracings that were initially nonreactive became reactive. The change in reactivity was significant (P =.013). Conclusion: Acute, repeated smoking decreases FHR reactivity. WebUnstressed or resting FHR tracings are indices of the following: (1) parasympathetic (vagal) tone; (2) sensitivity to sympathetic (adrenergic) discharge; (3) organization of fetal activity or behavioral states; (4) circadian rhythms; (5) the linkage between body movements and accelerations; (6) increasing stroke volume with reduction in resting …

WebFeb 13, 2024 · Reactive tests based on at least 2 accelerations (> 15 bpm, >15 s) in 20 min indicate fetal reassuring (well-oxygenated). Theoretically, in fetuses with heart block, FHR accelerations cannot be expressed and falsely interpreted as non-reassuring fetal well-being. WebFeb 17, 2024 · The baseline FHR is the average FHR from a 10-minute segment of a tracing, rounded to the nearest 5 bpm interval. The normal range of FHR at term is 110 to 160 bpm. If there is a change in the baseline rate that lasts for more than 15 minutes, then it is interpreted as changed. the primary function of the pinna is
