Apnea means "without breath" and refers to breathing that slows down or stops from any cause. Apnea of prematurity refers to breathing pauses in babies who were born before 37 weeks of pregnancy (premature birth).
Most premature babies have some degree of apnea because the area of the brain that controls breathing is still developing.

There are several reasons why newborns, in particular those who were born early, may have apnea, including:
Other stresses in a sick or premature baby may worsen apnea, including:
The breathing pattern of newborns is not always regular and may be called "periodic breathing." This pattern is even more likely in newborns born early (preemies). It consists of short episodes (about 3 seconds) of either shallow breathing or stopped breathing (apnea). These episodes are followed by periods of regular breathing lasting 10 to 18 seconds.
Irregular breathing may be expected in less mature babies. But the pattern of breathing and the age of the baby are both important when deciding how sick the baby is.
Apnea episodes or "events" that last longer than 20 seconds are considered serious. The baby may also have a:
How apnea is treated depends on:
Babies who are otherwise healthy and have occasional minor episodes are simply watched. In these cases, the episodes go away when the babies are gently touched or "stimulated" during periods when breathing stops.
Babies who are well, but who are very premature and/or have many apnea episodes may be given caffeine. This will help make their breathing pattern more regular. Sometimes, the nurse will change a baby's position, use suction to remove fluid or mucus from the mouth or nose, or use a bag and mask to help with breathing.
Breathing can be assisted by:
Some infants who continue to have apnea but are otherwise mature and healthy may be discharged from the hospital on a home apnea monitor, with or without caffeine, until they have outgrown their immature breathing pattern.

Apnea is common in premature babies. Mild apnea does not appear to have long-term effects. However, preventing multiple or severe episodes is better for the baby over the long-term.
Apnea of prematurity most often goes away as the baby approaches their "due date." In some cases, such as in infants who were born very prematurely or have severe lung disease, apnea may persist a few weeks longer.
