Apnea: When breathing stops for more than 20 seconds.
Bradycardia: A heart rate of less than 100 in a premature baby & 80 in a full term infant.
Pathologic Apnea: A breathing pause is abnormal if it is prolonged (at least 20 seconds) or combined with cyanosis (bluish color), pasty appearance, listlessness, or bradycardia.
Apnea of Prematurity: Periodic breathing with pathologic apnea in a premature infant. This usually resolves by the time the infact is 34-26 weeks gestational age.
I'll post more from the handout later, including the two main reasons for and the monitoring/management of apnea of prematurity.
