TRANSITION (first 6-8hrs after birth; SNS mediated)
* most healthy newborns experience transition regardless of gestational age or
type of birth
* very premature infants may not experience transition bc of physiologic
immaturity
First Period of Reactivity:Period of Decreased Responsiveness: Second
Period of Reactivity:
 lasts up to 30ish min after birth  lasts 60-100 min (1-2ish hours)  occurs btwn
hr 2 and 8
 HR s  to 160-180 bpm,  sleeps of marked reduction in motor  lasts from 10
min to several hr falls w/in 30 min to 100-120 bpm activity after 1st
period of reactivity  brief periods of tachycardia
 RR 60-80 breaths/min, irregular,  color is now pink and tachypnea
fine crackles on auscultation RR up to 60 breaths/min (rapid),  ed muscle tone
 Audible grunting, nasal flaring, chest retractions shallow but unlabored
 color changes may be present (should cease w/in 1st hour)  bowel sounds
audible  mucus production
 Alert, spontaneous startles, tremors, crying, head  peristaltic waves may be

visible over  meconium passed movement side-to-side rounded abdomen
 Audible bowel sounds, meconium may be passed
