Apnoea of prematurity |
One of the following is recorded in an infant <37 weeks conceptional age: |
Prolonged central respiratory pauses of The mechanisms by which oxygen therapy works is not entirely clear, but it is hypothesized that is has an effect on reducing peripheral chemoreceptor sensitivity to carbon dioxide which allows PaCO2 to elevate above the apnoeic threshold and reduces likelihood of instability ≥20 seconds in duration |
Shorter-duration events include obstructive or mixed respiratory patterns and are associated with a significant physiologic compromise, including decrease in heart rate, hypoxia, clinical symptoms or the need for nursing intervention |
Apnoea of infancy |
One of the following is recorded in an infant of conceptional age ≥37 weeks |
Prolonged central respiratory pauses of ≥20 seconds in duration |
Shorter duration events including obstructive or mixed respiratory patterns and are associated with bradycardia, cyanosis, pallor, or marked hypotonia |
For either diagnosis, the disorder is not better explained by another current sleep disorder, medical or neurologic disorder, or medication |
