Document Summary
Pregnancy unit: made up of maternal cv changes and maternal-placental and fetal-placental circulation. Maternal adaptations: mother will increase blood flow to several of her own organs to meet the needs of the baby (ex. Baby needs heat exchange-->mother increases blood flow to her skin: almost all hemodynamic changes in the mother are completely reversible after delivery (ex. Diaphragm is pushed up by growing baby and puts pressure on heart and lungs. After delivery, this is reversed: many of the maternal physiological changes occur before the uterine contents gain any significant weight (cid:894)(cid:1005)(cid:1004)(cid:449)ks(cid:895). This is the (cid:373)other(cid:859)s (cid:449)a(cid:455) of prepari(cid:374)g for the (cid:271)a(cid:271)(cid:455) Weight gain: 13. 4kg total, 8. 6kg tissue mass. 1. 0kg amniotic fluid: thin women can (cid:858)afford(cid:859) to gai(cid:374) (cid:373)ore (cid:449)eight duri(cid:374)g preg(cid:374)a(cid:374)(cid:272)(cid:455) tha(cid:374) o(cid:271)ese (cid:449)o(cid:373)e(cid:374, excess weight gain associated with gdm and macrosomia. Teratogens: caffeine is linked to sga and cvd later in life, alcohol is linked to a spectrum of disorders called fetal alcohol syndrome, preterm delivery and miscarriage.
