Central apnea is quite common and can be found in healthy, full-term infants for short periods of time before breathing patterns in the infant stabilize. [4] In premature infants, central apnea is attributed to an underdeveloped respiratory system which results in decreased response to higher carbon dioxide levels and difficulty breathing. [1]
Periodic breathing is clusters of breaths separated by intervals of apnea or near-apnea. As opposed to normal breathing which is usually regular, periodic breathing is defined as three or more episodes of central apnea lasting at least 4 seconds, separated by no more than 30 seconds of normal breathing.

Central sleep apnea is common in preterm, newborn, and infancy stages but a decrease in risk is found with aging and maturity of the central nervous system. Underlying neurological disorders are the most common cause of CSA in full term infants. Of the apnea related events in preterm infants born at less than 29 weeks, 25% are central in origin ...
Sleep apnea (sleep apnoea or sleep apnœa in British English) is a sleep-related breathing disorder in which repetitive pauses in breathing, periods of shallow breathing, or collapse of the upper airway during sleep results in poor ventilation and sleep disruption.
Obstructive apnea may occur when the infant's neck is hyperflexed or conversely, hyperextended. It may also occur due to low pharyngeal muscle tone or to inflammation of the soft tissues, which can block the flow of air though the pharynx and vocal cords. [1] Central apnea occurs when there is a lack of respiratory effort.
CPAP also may be used to treat pre-term infants whose lungs are not yet fully developed. For example, physicians may use CPAP in infants with respiratory distress syndrome. It is associated with a decrease in the incidence of bronchopulmonary dysplasia. In some preterm infants whose lungs have not fully developed, CPAP improves survival and ...
Transient tachypnea of the newborn occurs in approximately 1 in 100 preterm infants and 3.6–5.7 per 1000 term infants. It is most common in infants born by caesarian section without a trial of labor after 35 weeks of gestation. Male infants and infants with an umbilical cord prolapse or perinatal asphyxia are at higher risk.
Apnea can also be observed during periods of heightened emotion, such as during crying or accompanied by the Valsalva maneuver when a person laughs. Apnea is a common feature of sobbing while crying, characterized by slow but deep and erratic breathing followed by brief periods of breath holding.
