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]
It usually occurs when the infant is sleeping deeply, but may occur with light sleep or even when awake. Studies have shown that 78% of healthy full-term infants experience episodes of periodic breathing in the first two weeks of life, which typically resolves in the first six months of life. [2]
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 ...
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.
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 (also spelled apnoea in British English) [1] is the temporary cessation of breathing. During apnea, there is no movement of the muscles of inhalation , [ citation needed ] and the volume of the lungs initially remains unchanged.

Breath-holding spells (BHS) are the occurrence of episodic apnea in children, possibly associated with syncope (loss of consciousness and changes in postural tone).. Breath-holding spells occur in approximately 5% of the population with equal distribution between males and females.
