Fetal heart rate Flashcards
Normal fetal heart rate
110-160bpm
Indications of continuous electrical fetal monitoring
oxytocin infusion, epidural, hypertension, meconium presence
Category 1
normal fetal heart rate
Characteristics of category 1
moderate variability, no decelerations, acid-base status is normal
Category 2
indeterminate
Characteristics of category 2
unknown acid-base status, baseline tachycardia or bradycardia, variability present, decelerations present, no accelerations with stimulation
Management of category 2
measures to enhance oxygen delivery to the fetus
Category 3
abnormal fetal heart rate
Characteristics of category 3
no variability, recurrent decelerations, sinusoidal pattern
Interventions for category 3
IV fluids, oxygen, prompt delivery if no change, L/R lateral side positioning, knees to chest to increase placental perfusion and relieve cord compression
When is baseline FHR determined
when mom is not having any contractions
Variability
irregular fluctuations in baseline FHR
Absent variability
fluctuation undetectable
Minimal variability
fewer than 5bpm
Moderate variability
healthy! 6-25bpm
