Unformatted text preview: Chapter 16 Giving Birth 1 Uterine Contractions:
Opposing Characteristics Fig. 17-2 2 Components of the Birthing Process Powers Uterine contractions
• Frequency (beginning of one to beginning of next)
Duration (length in secs)
Intensity (strength) Cervical changes (dilation & effacement) Passageway- maternal pelvis (gynecoid)
Passenger-fetus, placenta, cord
Psyche- Mind-body connection---Anxiety, fear,
fatigue, or relaxation effects labor progress.
3 Cervical Changes (Powers) Cervical dilation- opening of cervix allows
passage of fetus; measured in cms (0-10
cms) Cervical effacement- thinning of cervix;
effacement measured percent (0-100%). Dilation & Effacement of cervix- components of labor. true 4 Plus 3 Patience - procession of labor at its own
pace- 1st delivery will take atleast 24 hr Presence - skilled support person Protection - creation of “Safe Nest” for
birthing Only intervention consistently reduced
rates of C/Ss is one-to-one support of
woman by nurse, nurse-midwife, or doula.

vertex or occipital bone, brow, and mentum (chin).
Breech-sacrum is reference point.
Transverse lie-AKA shoulder presentation; scapula is reference point Fetal position- relationship of reference point of fetal
presenting part to one of 4 quadrants of mother ’s pelvisleft or right & anterior or posterior.
Fetal station-relationship of presenting part of fetus to ischial
spines of maternal pelvis. When presenting part is at same
level of ischial spines, the station is “0” (zero) 10 Types of Cephalic Presentation 11 Left Occiput

Fetal Compromise Fetal heart rate (FHR) outside normal range
Little or no variability in FHR
Persistent slowing of FHR after UCs
Meconium-stained amniotic fluid
Cloudy, yellowish, or foul odor to amniotic fluid 25 Conditions Associated with Fetal
