Fetal Monitoring Flashcards
What is the most notable abnormality in FHR?
CP
At what time do we assess a FHR for normal vs. Abnormal?
8-12 weeks
What does FHR reflect?
Fetal oxygenation
Excessive amniotic fluid
Polyhydramnios
What doesn’t an external fetal monitor show?
Intensity
What is the most common uterine monitoring?
Toco transducer
Where is the uterine monitor placed?
On the maternal fundus; superior
What tightens with a contraction?
Maternal fundus
Frequency is measured in
Minutes
Duration is measured in
Seconds
The frequency shows
From the start of one contraction to the start of the next
The duration shows
From the start of one contraction to the end of the same contraction
What measures frequency, duration, intensity, and resting tone?
Internal fetal monitoring
ISE or FSE stands for
Internal or fetal scalp electrodes
IUPC
Intrauterine pressure catheter
Each small block on the fetal strip indicates how much time?
10 seconds
What does each large block on the fetal monitor indicate as far as time?
1 minute
A internal fetal monitor cannot be placed unless what happens first?
The membranes are ruptured and the cervix is dilated to at least 2cm
This is the pressure maintained in the uterus
Resting tone
The strength of the contraction is what? And can be palpated.
Intensity
What lies vertical on the monitor paper?
Rate
What lies horizontal on the monitor paper?
Duration
What is the average FHR on the monitoring paper?
Baseline
How long is a FHR monitored until the baseline is determined?
At least 10 minutes
