Pathophysiology: Both mother and baby begin to prepare for birth in the final weeks of pregnancy. The mother is instructed to call the health care provider and come into the birthing unit if any of the following occur. Rupture of membranes, regular, frequent uterine contractions (nulliparas, 5 minutes apart for one hour; multiparas, 6-8 minutes apart for 1 hour), any vaginal bleeding or decreased fetal movement. Family centered care is a model of care based on the philosophy that physical, sociocultural, spiritual, and economic needs of the family are combined and considered collectively when planning for the childbearing family. Five factors are important in the process of labor and birth. 1)Birth passage - is the size of the maternal pelvis or diameters of the pelvic inlet, midpelvis, and outlet. The type of maternal pelvis, and the ability of the cervix to dilate and efface and ability of the vaginal canal and the external opening of the vagina to distend. 2) The fetus-fetal head, fetal attitude, fetal lie, and fetal presentation. 3) Relationship between passage and fetusengagement of the fetal presenting part, station or location of fetal presenting part in the maternal pelvis in relation to the spine, and fetal position. 4) Physiologic forces of labor -frequency, duration, and intensity of uterine contractions as the fetus moves through the passage, and effectiveness of the maternal pushing effort.

5)Psychosocial considerations-mental and physical preparation for childbirth, socio-cultural values and beliefs, previous childbirth experience, support from significant other, and emotional status. Labor usually begins between 30 and 42 weeks of gestation. Pro just her own relaxes the smooth muscle tissue, estrogen stimulates uterine muscle contractions, and connective tissue loosens to permit the softening, thinning, and eventual opening of the cervix. In true labor, with each contraction the muscles of the upper uterine segment shortening and exert a Longitudinal traction on the cervix, causing effacement in which is the drawing up of the internal OS and the cervical canal into the uterine sidewalls. The contractions of true labor produced progressive dilation and effacement of the cervix. They only occur regularly and increase in frequency, duration, and intensity. The discomfort of true labor contractions usually starts in the back and radiates around to the abdomen. The pain is not relieved by ambulation. The contractions of false labor do not produce progressive cervical effacement and dilation. They are you regular and do not increasing frequency, duration, and intensity. The discomfort may be relieved by ambulation, changing positions, drinking a large amount of water, or taking a warm shower.

The first stage begins with the onset of true labor and ends when the cervix is completely dilated at 10 cm. The second stage begins with complete dilation and ends with the birth of the newborn. The third stage begins with the birth of the newborn and ends with the delivery of the placenta. Some clinicians identify a fourth stage. This stage lasts 1 to 4 hours after delivery of the placenta, the uterus effectively contracts to control bleeding at the placental site. Maternal systemic response to labor. The mothers cardiovascular system is stressed both by the uterine contractions and by the pain, anxiety, and apprehension she experiences. During pregnancy the circulating blood volume increases by 50%. The increasing cardiac output peaks between the second and third trimester. Maternal position also affects cardiac output. In the supine position, cardiac output lowers heart rate increases and stroke...
