title: Persistent Singultus: Addressing Complexity With Simplicity.
abstract: The hiccup reflex arc involving the brainstem, phrenic and vagus nerves, and the sympathetic chain is associated with singultus. There are many possible organic, psychogenic, idiopathic, and iatrogenic instigators. We describe a case of singultus in a 69-year-old man secondary to his CPAP mask, with resolution after he stopped using the mask. Our case establishes that CPAP may be a cause of iatrogenic aerophagia leading to gastric distention, singultus, and emesis and highlights the importance of a complete history.
