movements, posture, or changes in tone; (vi) what resuscitative efforts were made and the infant’s response to them; (vii) when the infant was last fed; (viii) how quickly the infant returned to baseline behavior The responses to these questions may provide the physician with clues to the diagnosis As an example, an 8month-old infant who was interrupted in a favorite activity, began to cry, turned red and blue, and finally had several seconds of tonic–clonic motor activity likely had a breath-holding spell In contrast, a history of 40 minutes of cyanosis and apnea in a now well-appearing child may be unreliable Other recent events that should be documented include symptoms of other illnesses, such as changes in behavior, activity, and appetite, as well as recent trauma and immunizations TABLE 14.4 COMMON LIFE-THREATENING CONDITIONS THAT CAUSE APNEA Pneumonia Sepsis/meningitis Hypoglycemia Seizures Intracranial hypertension Shock Ingestion (e.g., analgesics, sedatives, muscle relaxants)
