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
