OB Week 2: Physiologic and Behavioral Adaptations of Newborn
1. Newborn: birth to 28 days old
2. First stage after birth: First period of reactivity
up to 30 mins. after birth
can have: tachycardia, tachypnea, crackles, nasal flaring, grunting, retractions
best time to breast feed
3. second stage after birth: Period of decreased responsiveness
lasts 60-100 minutes
marked decreased motor activity
4. Third stage after birth: second period of reactivity
happens 2-8 hours after birth
can last 10 min to hours
tachycardia, tachypnea
pass first stool
5. acrocyanosis: normal first 24 hours
6. surfactant: if not enough, baby becomes tired
1/5
, preterm/sick babies may have none so at risk for resp. distress
7. signs of respiratory distress: nasal flaring
retractions
grunting
seesaw breathing
resp. rate <30 or 60> at rest
8. cutting the cord: inhibits prostaglandins so respiratory is stimulated
turns into ligament in 2-3 months
