Once a baby is born, he or she needs to breathe continuously to get oxygen. In a premature baby, the part of the central nervous system (brain and spinal cord) that controls breathing is not yet mature enough to allow nonstop breathing. This causes large bursts of breath followed by periods of shallow breathing or stopped breathing. The medical term for this condition is apnea of prematurity, or AOP.
When used alone, the asthma medications known as long-acting beta-agonists are associated with an increased risk of serious complications, new research indicates.
