⩥ Pattern recognition & intervention.
Answer: -FHR baseline ✓
-FHR variability ✓
-FHR accelerations ✓
-FHR decelerations ✓
-Normal uterine activity ✓
-Abnormal uterine activity ✓
-Fetal dysrhythmias ✓
-Maternal complications ✓
-Uteroplacental complications ✓
-Fetal complications ✓
⩥ FHR Descriptors.
Answer: 1) Baseline
2) Variability
3) Presence of accels
,4) Presence of decels
5) Changes in trends overtime
⩥ FHR Baseline.
Answer: Average FHR rounded to nearest 5 during a 10 min window
-110 to 160
-excludes accels, decels, & marked variability
-must have 2 mins to identify as a baseline (doesn't need to be
continuous)
⩥ Fetal Bradycardia.
Answer: <110 for ≥10 min
-Causes: hypotension (ex: after epi), cord prolapse, head compression,
congenital defect, rapid descent, abruption or rupture, tachysystole, post
dates, hypoglycemia, lupus (heart block)
-With ↓ O2, blood will be shunted to brain, heart, & adrenals, eventually
↓ FHR to ↓ O2 demands of heart muscle
-Verify not mom's HR, vaginal exam (r/o prolapse), resuscitate, evaluate
arrhythmia, expedite delivery
⩥ Fetal Tachycardia.
Answer: >160 for ≥10 min
, -Causes: fetal anemia, maternal fever or infection, fetal immaturity
(preterm), SVT, maternal anxiety (catecholamines), dehydration,
hyperthyroid, hypoxia
-Med causes: terbutaline, catecholamines (epinephrine, norepi)
-Assess mom's temp & infection risk (GBS, PROM)
⩥ FHR Variability.
Answer: Irregular in amplitude & frequency, quantified by peak to
trough
-Caused by sympathetic vs parasympathetic, r/t neuro maturity
-Less in preterm due to undeveloped CNS
-Absent: undetectable, flat
-Minimal: ≤5 bpm but detectable
-Moderate: 6-25 bpm
-Marked: >25 bpm (indeterminate baseline), significance unknown
⩥ Minimal variability.
Answer: ≤5 bpm but detectable
Sleep, sedated, or sick
-Sleep cycle: 20-60 mins
-Sedated: CNS depressant (ex: mag), 1-2 hrs
-Sick (acidemia): unresolved w intervention
-Priority: maximize oxygenation (position, bolus, O2 if needed)
