 Signs of heat stroke include confusion and slurred speech, loss of consciousness, hot, dry skin or profuse sweating, seizures, and very high body temperature. Please take the heat seriously. And remember that Riverview's emergency department is always open if the heat makes you sick. Riverview is offering its monthly CPR classes tomorrow at 6 p.m. One class is for certification with a cost of $55, and the other is called the Friends and Family class.
