Electronic Fetal Heart Rate Monitoring:
What is the normal BPM?
(Over a 10 minute segment, between contractions)
110-160 BPM
Electronic Fetal Heart Rate Monitoring:
What is the bradycardia BPM?
(Over a 10 minute segment, between contractions)
<110 BPM
Electronic Fetal Heart Rate Monitoring:
What is the tachycardia BPM?
(Over a 10 minute segment, between contractions)
> 160 BPM
What is the most important indicator of fetal well-being? Visually detectable FHR oscillations from the baseline.
Variability
What does variability represent?
Represents intactness of fetal CNS
What are the 4 different levels of variability?
absent, minimal, moderate, or marked variability
Depending on the amplitude of the waves
What are periodic changes?
Changes from the fetal heart rate baseline that are associated with uterine contractions
What are episodic changes?
Changes from the fetal heart rate baseline that are not (or are in between) associated with uterine contractions
What is this describing?
- May be either periodic or episodic
- Are visually apparent abrupt increases in FHR above baseline
- Goal: peak > 15 BPM, duration >15 sec but
Accelerations
What is this describing?
- Are periodic
- Are visually apparent gradual decreases in FHR below baseline. Onset to nadir > 30 sec and coincident with the onset, peak, and ending of contractions
- Does not require additional nursing action
Early decelerations
What are early decelerations caused by?
Fetal head compressions
What is this describing?
- Are periodic
- Visually apparent gradual decrease in FHR below baseline
- Onset to nadir > 30 sec and delayed in timing to peak of contraction
- Requires interventions
Late decelerations
What causes late decelerations?
uteroplacental insufficiency/fetal hypoxia
-requires interventions to enhance fetal oxygenation and placental perfusion
What causes variable decelerations?
What are the interventions?
Caused by cord compression
Interventions aimed at eliminating cord compression, increasing fetal oxygenation
What causes prolonged decelerations?
Many causations: prolapsed cord, tachysystole, rapid decent, abruption, etc
What term is this describing?
Mean FHR rounded to increments of 5 bpm during a 10 minute segment excluding periodic or episodic changes, periods of marked variability and segments of baseline that differ by 25 bpm. Duration must be > 2 minutes
Baseline Rate
What term is this describing?
Fluctuations in the baseline FHR of 2 cycles/min or greater. Visually quantitated as the amplitude of the peak-to-trough in beats per minuute
Variability
What term is this describing?
Amplitude from peak to trough undectable
absent variability
What term is this describing?
Amplitude from peak to trough >undetectable and < 5 bpm
minimal variability
What term is this describing?
Amplitude from peak to trough 6-25 bpm
moderate variability
What term is this describing?
Amplitude from peak to trough > 25 bpm
marked variability
In gestations <32 weeks, peak of 10 bpm and duration of 10 seconds is….
Acceleration, if >32 weeks is 15 bpm and 15 sec
What term is this describing?
Visually apparent abrupt decrease (onset to nadir is < 30 sec) in FHR below baseline. Decrease is >15bpm, duration >15 sec and < 2 min
Variable deceleration
What term is this describing?
Visually apparent abrupt decrease (onset to nadir s < 30 sec) in FHR below baseline. Decrease is > 15 bpm, duration >2min but <10 min
Prolonged deceleration
What are the 3 phases of the first stage of birth?
- Latent phase
- Active phase
- Transition phase
What is the approximate time for the Latent Phase?
6-8 hours
What is the dilation for the latent phase?
0-3cm
What are the contractions frequency, duration and intensity in the Latent Phase?
Every 5-30 minutes
30-40 sec
Mild progress to moderate
25-40 mmHg IUPC
What is the approximate length of time for the Active Phase?
Approx. 3-6 hours
What is the dilation in the Active Phase?
4-7cm
What are the contractions frequency, duration, and intensity in the Active Phase?
Every 3-5 min
40-70 sec
Moderate progress to strong
50-70 mmHg by IUPC
What is the approximate length of time for the Transition Phase?
approx. 20-40 minutes
What is the dilation in the Transition Phase?
8-10 cm
What are the contractions frequency, duration, and intensity in the Transition Phase?
Every 2-3 minutes
45-90 sec
Strong by palpation
70-90 mmHg by IUPC
How long is the second stage? Nullipara and Multipara
Influenced by regional anesthesia
Nullipara: 50 min-2hr
Multipara: 20 min-1hr
What are the 3 types of breathing patterns to comfort for labor and birth?
Slow Breathing Pattern -in through nose, out through mouth -begin when mom has difficulty walking during contractions Light Breathing or Accelerated Breathing -Use when tense -silent inhale, audible exhale -"greet" the contraction w/ cleansing breath -end contraction with another "blow it away" Transition Breathing -pant-pant-blow -he-he-he-blow
What are some techniques to relieve backache during labor and birth?
hands and knees position, pelvic rocking, lunge, walking, stair climbing, slow dancing, birthing ball, changing positions, cold packs, rolling pressure (tennis balls, rolling pins), counter pressure
What are some other effective comfort measures?
Visualization/attention focusing, music and aroma therapy, tub/shower, cold or hot pack, massage techniques, palm massage, effleurage
What are 3 bearing down techniques?
- “Laboring down” or push only with the urge
- Directed pushing or valsalva pushing
- Open-glottis pushing
What are 4 positions for comfort?
Squatting, semi-sitting, hands and knees (easy, help rotate baby, may help the FHR), and dangling (elongates the trunk, relaxes the pelvis)
