(A) Charting swallow-integrated pharyngoesophageal motility study in an infant with feeding success describing propagation of spontaneous dry swallow, wet swallow–induced primary peristalsis, and oral feeding challenge test. (B) Charting similar data in an infant with feeding failure describing failed propagation of dry swallow, response failure to wet swallow, and poor response to oral feeds. EMG = electromyography; UES = upper esophageal sphincter; PE = proximal esophagus; ME = mid esophagus; DE = distal esophagus; LES = lower esophageal sphincter.
