Periodic breathing in the newborn

Discussion

  • Periodic breathing is characterized by 3 or more episodes of central apneas, each lasting longer than 3 seconds, and separated by continuous respiration of less than 20 seconds. There may or may not be significant desaturations with the events.
  • Periodic breathing is considered a benign condition in infants and frequently observed in preterm infants. It is not a precursor of significant apnea and usually decreases with increased gestational age.
  • Periodic breathing in the newborn is believed to be secondary to immaturity in chemoreceptor function and central control of breathing.
  • Periodic breathing is more prevalent in active sleep (represented in the fragment) compared with quiet sleep, and is increased during fever, with significant GE reflux, with high ambient temperature, and at high altitude.
  • Periodic breathing has been found to respond to methylxanthines and low-flow supplemental oxygen. Indications for treatment include: associated heart decelerations, oxygen desaturations, or prolonged periods exceeding 4-10% of total sleep time.
