apneic spell
Episode of breathing cessation lasting 20 seconds or more, or shorter if accompanied by bradycardia or desaturation.
Full Definition
An apneic spell represents a concerning episode where breathing ceases for a clinically significant period, defined as 20 seconds or longer, or shorter durations when accompanied by bradycardia (heart rate less than 100 bpm) or oxygen desaturation. In premature infants, these episodes are common due to immature respiratory control mechanisms and can be classified as central (no respiratory effort), obstructive (continued effort against obstruction), or mixed. Apneic spells require careful monitoring and may necessitate intervention including stimulation, repositioning, or respiratory support. Frequent or severe episodes may indicate underlying pathology requiring investigation and treatment.
