Collaborative Care- Vomiting

Contents of emesis: Emesis containing partially digested food several hours after a meal is indicative of gastric outlet obstruction or delayed gastric emptying. Color of emesis: Vomitus with a "coffee ground" appearance is related to gastric bleeding, where blood changes to dark brown as a result of its interaction with HCl acid.
