Chapter 16 Flashcards
Components of the Birthing ProcessTHE FOUR P’s**
Powers -contractions and pushing
Passage- uterus/vagina and pelvis
Passenger - fetus
Position of the the laboring woman
Powers
Uterine contractions- first stage
Maternal pushing- second stage
Contractions
INCREAMENT
PEAK
DECREMENT
Contraction Measure
- FREQUENCY 2. DURATION 3. INTENISTY 4. INTERVAL
coordinate more intense contractions at the top
makes it so you can push out baby; stretches at bottom so baby can come out
no rest for mother until
baby comes out
increment
as contraction builds
decrement
as contraction comes down
duration *
beginning of 1 contraction to end of same contraction
if contraction longer than ____ then worry
90 seconds; the longer the contraction the more likely for the baby to have distress
internal rest period *
from 1 contraction to the next
frequency
the beginning of contraction to the beginning of the next; includes 1 contraction and interval (rest period)
can measure intensity of contraction by
put hand on woman and feel
if mild contraction will feel like
tip of the nose
if moderate contraction will feel like
chin
if firm contraction will feel like
forehead
how do contractions help in labor
helps baby come down and out more easily
Uterine Contractions-
The upper 2/3 contracts and the lower1/3 & cervix are passive and separated by the physiologic retraction ring
effacement
thinning & shortening of the cervix 0- 100%
dilation
widening of the cervical os 1 to 10 CMS
10 cms =
100 % effaced, time to push
multigravida -
2nd or more baby, so delivery goes faster
primigravida -
dilate before labor begins
relaxant
release when labor tarts so pelvis can be stretched
