Apnea is a pause in breathing that has one or more of the following characteristics:
lasts more than 15-20 seconds
is associated with the baby's color changing to pale, purplish or blue
is associated with bradycardia or a slowing of the heart rate
Bradycardia is a slowing of the heart rate, usually to less than 80 beats per minute for a premature baby. Bradycardia often follows apnea or periods of very shallow breathing. Sometimes it is due to a reflex, especially with the placing of a feeding tube or when the baby is trying to have a stool.
No, apnea of prematurity is by far the most common cause of apnea in a premature infant. However, apnea can be caused or increased by many problems including infection, low blood sugar, patent ductus arteriosus, seizures, high or low body temperature, brain injury or insufficient oxygen.
Premature babies have immature respiratory centers in the brain. Preemies normally have bursts of big breaths followed by periods of shallow breathing or pauses. Apnea is most common when the baby is sleeping.
As your baby gets older, his/her breathing will become more regular. The time course is variable. Usually apnea of prematurity markedly improves or goes away by the time the baby nears his/her due date.
Several treatments are possible. Your baby may be treated with one or more of the following:
Medications that stimulate breathing. Commonly used drugs include theophylline, aminophylline, or caffeine.
CPAP or continuous positive airway pressure. This is air or oxygen delivered under pressure through little tubes into the baby's nose.
Mechanical ventilation (breathing machine). If the apnea is severe, the baby may need a few breaths from the ventilator every minute. These might be given at regular intervals or only if apnea occurs.
A rocking bed or periodic stimulation
Your baby's respirations are monitored continuously if s/he is at risk for apnea. An alarm will sound if there is no breath for a set number of seconds.
A nurse will observe your baby to see if s/he is breathing, if there is a change in color or if the heart rate is falling. False alarms occur often.
The nurse may stimulate your baby if your baby needs a reminder to breathe.
If there is a change in color, the nurse may give your baby extra oxygen.
If your baby still doesn't breathe, s/he may give the baby a few breaths with a bag and mask, or extra breaths on the mechanical ventilator.
Most infants are over their apnea completely when
they go home; however, some babies reach all other criteria for discharge before
their apnea is completely gone. Some babies are candidates for home apnea
monitoring. Your baby may be a candidate for home apnea monitoring if :
s/he has apnea that is short and s/he recovers without any stimulation
s/he has no color change or bradycardia with the apnea
the apnea is not expected to go away in the next several days
your nursery has a home apnea program
you have a phone and live near emergency help (if you would need it)
you, and usually a second person, have completed home apnea training and a course in cardiopulmonary resuscitation of a baby
your baby's doctor feels this is a good idea for your particular baby
Apnea of prematurity is a result of immaturity. Once a baby matures and the apnea resolves, it will not return. If a baby should have breathing pauses after apnea goes away, it is not apnea of prematurity. It is due to some other problem and needs to be discussed with your baby's physician. This is not common.
No, these are two entirely different problems. Most babies who die of SIDS are born at term and have normal newborn stays. Babies who have needed newborn intensive care for any reason are at a slightly higher risk of SIDS than other babies. Apnea of prematurity does not determine this risk.
