title: Development of the control of breathing: implications for sleep-related breathing disorders in infants.
abstract: Abnormal development of the control of breathing has implications for the occurrence and severity of SDB during infancy. Prevention of prenatal insults such as nicotine exposure should be included in public health programs. Infants at risk for SDB or with symptoms of SDB should be investigated for peripheral and central chemoreceptor dysfunction. Peripheral chemoreceptor function can be assessed using either the hyperoxic test or the alternating breath test, and central chemoreceptor function using the rebreathing test. Optimal treatment of SDB in the developing infant is of central importance for preserving normal behavior and neurocognitive development. Oxygen supplementation and/or ventilatory support during sleep prevent uncontrolled episodes of hypoxemia, sleep fragmentation, and REM sleep reduction. Finally, alterations in homeostatic responses during development may have long-term effects on breathing during sleep in childhood and adulthood. In genetically-predisposed subjects, environmental conditions during the period of development of respiratory control mechanisms may add to the intrinsic vulnerability to SDB.
