PROBLEM STATEMENT:

PROBLEM STATEMENT On his first visit to the beach, a man drinks a good amount of sea water while swimming. He feels thirsty after some time and decides to drink beer; after which he felt thirstier, develops a headache, dry mouth, dizziness, lightheadedness and finally collapses. He is told later at the hospital that his blood pressure had been 90/60.

OBJECTIVES:
