EXAM 1- FETAL HEART MONITORING
What is *fetal heart monitoring*?
- purpose
- done through what methods
- goal to reduce ___ - ANS-- measures the heart rate and rhythm of your baby
- lets your healthcare provider see how your baby is doing
- primary evaluation tools used to determine fetal oxygen status indirectly
- can be done intermittently through fetoscope or doppler
OR
- can be done continuously with an electronic fetal monitor internally or externally
- GOAL: to reduce mortality/morbidity by ensuring all fetal hypoxic insults are identified
in time
What is *intermittent FHR monitoring*?
- uses 2 types
- does not
- assessed for ___ seconds - ANS--periodically listening to baby's heartbeat at set times
throughout labor by pressing a special stethoscope or Doppler
- can use *Fetoscope*: a modified stethoscope attached to a headpiece -> assesses
FHR
- can use *Doppler*: an ultrasound device that uses waves to bounce of fetal heart
- allows women to be mobile in first stage of labor
- DOES NOT
> provide continuous FHR recording
> document ow fetus responds to stress
> detect variability and types of decelerations
, - FHR is assessed for full minute after a contraction to establish baseline
- then on, listen for 30 seconds
- most clearly heard at fetal back (lower quadrant of mother)
What is *Continuous External FHR monitoring*? - ANS-- 2 ultrasound transducers are
attached to a belt around woman's abdomen
- one is used for sensing uterine contractions while the other senses the baseline FHR,
long-term variability, accelerations, and decelerations
- can measure approx duration and frequency of contractions
- can be used when membranes are intact with undilated cervix -> OR if not intact and
dilated
What is *Continuous Internal FHR monitoring*?
- given for
- done how
- 4 requirements to use this - ANS-- indicated for women or fetuses considered high risk
- involves placement of spiral electrode in the fetal presenting part
- electrode is most accurate method of detecting fetal heart characteristics
4 REQUIREMENTS
*(1)* ruptured ROM
*(2)* cervical dilation of at least 2 cm
*(3)* Presenting fetal part low enough to place electrode
*(3)* Skilled practitioner to insert it
What is *Internal Uterine Pressure Catheter*?
- used for
- what can it tell
What is *fetal heart monitoring*?
