Pediatric hypoventilation syndromes

Hypoventilation syndromes are an uncommon but important group of respiratory control disorders in infants and children. Congenital central hypoventilation syndrome (CCHS) is the principal and most important example. No specific anatomical or biochemical mechanism has yet been identified. This article summarizes current knowledge regarding CCHS in infants and children, and emphasizes the most recent and most important publications. The most recent advances in CCHS pertain to its genetics, pathophysiology, diagnosis, and treatment and provide state-of-the-art information regarding advances in diaphragm pacing, responses to exercise, and long-term outcome. CCHS is now being recognized more frequently, treatment is more successful, and long-term outcomes are encouraging with timely diagnosis, state-of-the-art treatment, and comprehensive follow-up at an experienced pediatric referral center.
