Hiccups Hiding in the Waveforms

Breaths 2 and 5 in the following waveforms demonstrate a marked pressure drop below baseline, accompanied by higher peak inspiratory flow and a rapid return of flow to baseline compared to the surrounding breaths. When such brief, strong inspiratory efforts are observed, it is important to consider hiccups as the cause, since hiccups generate sudden, short-duration diaphragmatic contractions that produce this characteristic waveform pattern
