L&D/Maternal-Fetal Monitoring/Quick Notes Flashcards
Baseline FHR
110-160 beats/min
Saunders 348
Fetal Bradycardia
FHR less than 110 beats/min for 10 minutes
Fetal Tachycardia
FHR greater that 160 beats/min for 10 minutes
If fetal brady or tachycardia occur... Nursing actions (4)
1) Reposition mother
2) Admin oxygen (non rebreather 15 l)
3) Assess mothers VS
4) Notify Provider
Variability
Fluctuations in baseline FHR
Reassuring FHR pattern
Reassuring FHR patterns are those that are associated with fetal well-being and lack of acute distress. Reassuring FHR readings include periodic accelerations, mild variable decelerations lasting less than 30 seconds, or early decelerations that mirror contractions in duration and timing
Nonassuring FHR pattern
Nonreassuring FHR patterns are those that suggest fetal compromise or a declining ability to cope with the stress of labor.
Nonreassuring patterns include a significant decrease in baseline variability or baseline heart rate, progressive fetal tachycardia or bradycardia, persistent late decelerations, or recurrent late return to baseline after decelerations.
Accelerations
Brief FHR increase 15 beats/min for 15 secs
Brief FHR increase 15 beats/min for 15 secs
Assuring or nonassuring?
Assuring
Reactive test if at least 2 in 20 minutes
Non reactive result
Acceleration not present or does not meet Assuring criteria
indicates fetus at risk or asleep
Late decelerations are (2) caused by
1) impaired placental exchange
2) Uteroplacental insufficiency
Nonreassuring Fetal Heart Rate Patterns (8)
Saunders 350
1) Brady
2) Tachy
3) Late decele
4) Prolonged decel
5) Hypertonic uterine activity
6) Decrease or Absent variability
7) Variable decelerations falling less than 70 beats/min for longer than 60 minutes
8) Undetected variability
Nonreassuring Fetal Heart Rate Patterns
Priority Nursing Actions
(Saunders 350)
1) Identify cause
2) dc oxytocin (pitocin) infusion
3) Change mother’s position
4) Oxygen 8-10 l non rebreather
5) Infuse IV fluids
6) FHR assess, continue monitoring
7) C-section in needed
8) Document: Event, actions taken, mother’s response
9) Notify provider
Nonreassuring Fetal Heart Rate Patterns
Priority Nursing Actions
Identify cause
1) Prolapsed cord
2) Hypo or hypertension
3) Fever
4) Oxytocin stop infustion, tocolytic may be prescribed
Variable decelerations indicate
Variable decelerations falling less than 70 beats/min for longer than 60 minutes before returning to baseline
restricted flow to umbilical cord
