Algorithm-detected episode of central neonatal apnea. This constellation of signals is consistent with an episode of central apnea with bradycardia and desaturation. Time 0 is the center point of the apnea event. The results of the automated detection appear below the clinical data tracings as described in text. Abbreviations: ABD, apnea, bradycardia, and desaturation event; bpm, beats per minute; EKG, electrocardiograph; IP, impedance pneumography; SpO2, pulse oximetry.
