The Passage Way Flashcards
Passageway: The birth canal that is composed of (5)
1) Bony Pelvis2) Cervix3) Pelvic floor4) Vagina5) Introitus (vaginal opening)
Passageway: False Pelvis
False pelvis lies above the pelvic brim
Passageway: True Pelvis
True pelvis represents bony limits of birth canalMeasurements: Transverse and anterior-posterior
Passageway: Four pelvic types
1) Gynecoid2) Android3) Anthropoid4) Platypelloid
Passageway: Effacement(Powers: Primary Forces)
With each contraction muscles of upper uterine segment shorten and exert longitudinal traction of cervix causing effacement, drawing up internal os and cervical canal into uterine side walls. Measured 0 to 100%(Hogan 161)
Passageway: Dilatation(Powers: Primary Forces)
Open of cervix: as uterus elongates with contractions, fetal body straightens and exerts prussure against lower uterine segment and cervix. Measured 0 to 10 cm
Bishop Score1) What is it measuring?2) Range?3) Score less than 6 means?
To prepare for labor and delivery, the cervix begins to soften (ripen), thin out, and open. These changes usually start a few weeks before labor begins. Health care providers use the Bishop score to rate the readiness of the cervix for labor. With this scoring system, a number ranging from 0–13 is given to rate the condition of the cervix. A Bishop score of less than 6 means that your cervix may not be ready for labor
