Blue in Sleep, Pink by Day: A Neonate with Congenital Central Hypoventilation
Blue in Sleep, Pink by Day: A Neonate with Congenital Central Hypoventilation - Sleep Medicine clinical simulation case. Six-day-old full-term female...
Six-day-old full-term female neonate, born to a healthy primigravida mother via uncomplicated vaginal delivery, presenting with recurrent cyanosis and apnea exclusively during sleep, normal breathing and pink color when awake, no structural heart or lung disease identified on prior workup, currently admitted to the Level III NICU.
Acute Resuscitation Milestones & Priorities
Clinical phases and key interventions encountered in this emergency module:
Phase 1: Sleep-Only Cyanosis Recognition
Phase 2: Confirm Central Hypoventilation & Initiate Sleep Ventilatory Support
Phase 4: Definitive Home Care, Tracheostomy Decision & Family Training
High-Yield Clinical Pearls
Congenital Central Hypoventilation Syndrome is suspected in any infant with cyanosis or apnea confined to sleep with immediate correction on arousal and absent respiratory distress.
Polysomnography with capnography is the diagnostic gold standard; awake drive is preserved while sleep drive fails, producing hypercapnia without increased work of breathing.
PHOX2B polyalanine repeat expansion (PARM) confirms the diagnosis; the 20/25 genotype is the most common and informs screening for Hirschsprung disease, neuroblastoma, and cardiac pauses.
First-line treatment is non-invasive positive pressure ventilation with backup rate during sleep; tracheostomy with home ventilation is definitive when non-invasive support fails or causes facial injury.
Supplemental oxygen alone is contraindicated: it masks hypercapnia, does not address absent drive, and risks CO2 narcosis and death.
