Irregular in amplitude &
frequency, quantified by peak
to trough
-Caused by sympathetic vs
parasympathetic, r/t neuro
FHR Variability
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
≤5 bpm but
detectable Sleep,
sedated, or sick
Minimal variability
-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)
6 to 25 bpm
Moderate variability
-Reliably predicts the absence of metabolic acidosis (even w
decels)

Reliably predicts absence of
metabolic acidemia
(spontaneous or stimulated)
-Onset to peak in <30 sec
FHR Accelerations
-For ≥32 wks: 15x15 (peak ≥15 bpm
above baseline lasting ≥15 sec)
-For <32 wks: 10x10
-Prolonged accel: 2-9 mins (at 10
becomes change of baseline)
Nadir aligns w contraction peak,
gradual onset (≥30 secs to
nadir), benign vagal response
1) Pressure on fetal head
Early deceleration
2) Increased intracranial pressure
3) Alteration in cerebral blood flow
4) Central vagal stimulation
5) FHR deceleration
Periodic: caused by contractions
-recurrent: occurs w ≥50% of contractions in 20 min
Periodic vs Episodic
-intermittent: w <50% of
contractions in 20 mins Episodic:
spontaneous
Caused by cord compression
-Interventions: position change, amnioinfusion
Variable deceleration -Abrupt onset: <30 seconds
from onset to nadir dropping
≥15 bpm lasting 15 secs to
<2min
-Transient rise in PCO2 & fall in PO2
Abruptness r/t pressure changes
1) Vein obstruction → reflex tachy
-↓ venous return & cardiac output → hypotens →
Mechanisms of variable baroreceptor reflex ↑ in FHR to maintain BP
decelerations 2) Arterial obstruction → decreased FHR
-obstructed blood flow back to placenta → HTN →
baroreceptor reflex of slowing FHR to maintain BP

Uteroplacental insufficiency
-Indicative of transient fetal hypoxemia
-Gradual onset: ≥30 secs to
Late decelerations nadir w nadir occurring after
peak of contraction
-Priority is to maximize
uteroplacental blood flow:
position lateral (off vena cava &
aorta), fluid bolus (perfusion),
O2, avoid tachysystole
Low O2 → chemoreceptor response peripheral
vasoconstriction → blood flow to vital organs → HTN
→ baroreceptor vagal stimulation → FHR decel
1) Decreased uteroplacental oxygenation (transient hypoxemia)
2) Chemoreceptor stimulation
Mechanisms of a late 3) Alpha adrenergic response (catecholamines, peripheral
deceleration vasoconstriction)
4) Fetal HTN
5) Baroreceptor stimulation
6) Parasympathetic response
7) FHR deceleration
8) ↓ myocardial stress
