Flashcards in Labor Deck (13):
1

labor

cervical change + regular contractions

2

latent phase

mostly effacement (cervix <4cm)

3

active phase

dilation occurs more rapidly (cervix >4cm)

4

protraction of active phase

dilation <1.5/hr for multip

5

arrest of active phase

no progress for >2hrs

6

first stage of labor

onset to complete dilation

7

second stage labor

complete dilation to delivery

8

third stage labor

delivery infant to delivery placenta

9

FHR: normal, tachy, brady

normal = 110-160

10

adequate contractions

ev 2-3min, firm to palpation, last 40-60seconds (OR >200MVU)

11

Category 1 tracing

normal baseline + variability, no late/variable decels

12

Category 2 tracing

some concerning aspect, but not ominous (fetal tachy without decels)

13

Category 3 tracing

omnious, high liklihood of fetal hypoxia (absent baseline variability with recurrent late or variable decels or bradycardia; or sinusoidal HR pattern)
