AND 100% CORRECT WELL DETAILED
Purpose of FHR monitoring - ANSWER - give info. about fetal oxygenation & prevent
fetal injury from impaired Oxygenation
- detect FHR changes before they are prolonged & profound
Leopold's Maneuver - ANSWER determine position of the fetus & to assist with
monitor placement
Timing of uterine contractions (UC's) - ANSWER - frequency
- duration
Frequency - ANSWER how often contractions happen--count from start of 1
contraction to the start of the next
Duration - ANSWER how long the contraction lasts--count from the start of one
contraction to the end of the same contraction
Tachysystole/Uterine Hyperstimulation - ANSWER more than 5 UC's in 10 minutes OR
2 UC's lasting more than 120 seconds in duration
NEEDS INTERVENTION!!
What needs to be determined to interpret FHR? - ANSWER 1. baseline FHR
2. FHR variability
1
, 3. Are HR accelerations present?
4. Are decelerations present? If yes, which variety?
5. Determine the FHR category
6. Is intervention necessary?
Baseline FHR - ANSWER 110-160 bpm (need at least 20 mins. to determine a baseline)
Tachycardia: > 160 bpm
Bradycardia: < 110 bpm
FHR Variability - ANSWER how many beats of change in the HR from the baseline
Absent: no changes
Minimal: 0-5 beats of change
Moderate: 6-25 beats of change
Marked: > 25 beats of change
Absent Variability - ANSWER no detectable change from baseline
Minimal Variability - ANSWER <5 bpm change from baseline
Moderate Variability - ANSWER 6-25 bpm change from baseline
Marked Variability - ANSWER > 25 bpm change from baseline
Accelerations in FHR - ANSWER 15 beats above baseline FHR for 15 seconds
