Case study:
Dale Fremore was back home after spending the day at a picnic
where he ate some "spoiled" potato salad. He developed severe
abdominal pain and cramps, vomiting, and diarrhea. After about
ten to twelve episodes of water diarrhea, Mr. Fremore became so
pale and weak he could hardly walk. His wife took him to the

(decreased plasma volume). Mr. Fremore was suffering from
shock.

to maintain blood pressure and blood flow when a person goes
into shock.
