This handheld device is commonly used in the OB office during the second and third trimesters for intermittent fetal heart rate assessment.
What is a Doppler?
This is the normal fetal heart rate baseline.
What is 110–160 bpm?
This fetal heart rate change is reassuring and signifies fetal well-being.
What is an acceleration?
No intervention is required for this fetal heart rate pattern because it is considered reassuring.
What are accelerations?
This outpatient fetal assessment test evaluates fetal well-being without contractions.
What is a Non-Stress Test (NST)?
This external monitor is placed over the area where the fetal heart sounds are best heard.
What is the ultrasound transducer?
This type of variability indicates the healthiest fetal neurological status.
What is moderate variability?
This deceleration results from fetal head compression.
What is an early deceleration?
This is the first intervention for recurrent late decelerations.
What is maternal position change?
A reactive NST in a term fetus requires at least this many accelerations.
What are 2 accelerations?
This external monitor detects uterine contractions but cannot measure their intensity.
What is the tocotransducer (toco)?
This variability pattern is expected in a sleeping fetus or a premature fetus.
What is minimal variability?
This deceleration is caused by umbilical cord compression.
What is a variable deceleration?
This is the first intervention for recurrent variable decelerations.
What is discontinue Pitocin?
Each acceleration for a reactive NST in a term fetus must increase by this amount and last this long.
What is 15 bpm for 15 seconds (15×15)?
This internal monitor directly measures uterine pressure and contraction intensity.
What is an IUPC (Intrauterine Pressure Catheter)?
This ominous wave-like fetal heart rate pattern is excluded from variability and often requires immediate delivery.
What is sinusoidal pattern?
This deceleration is associated with uteroplacental insufficiency.
What is a late deceleration?
This medication is considered one of the last interventions because it is treated as a drug.
What is oxygen (10 L/min via nonrebreather mask)?
Most laboring patients fall into this fetal heart rate category.
What is Category II?
These two conditions must be present before internal fetal monitors can be inserted.
What are ruptured membranes and cervical dilation?
This is the most common maternal cause of fetal tachycardia.
What is maternal fever?
A fetal heart rate decrease lasting more than 10 minutes is classified as this instead of a deceleration.
What is a baseline change (bradycardia if <110 bpm)?
This procedure may be performed during recurrent variable decelerations when amniotic fluid is low.
What is an amnioinfusion?
This fetal heart rate category predicts abnormal fetal acid-base status and requires expedited delivery.
What is Category III?
