Emergency care includes the following: t • Remove the patient, when possible, from the source of heat. • Call an ambulance. ' . Remove as much of the patient's clothing as possible or reasonable, pour cool water over his/her body (avoiding the nose and mouth), fan the patient briskly, and shade from the sun if he/she is still outdoors. Wrapping a wet sheet around the patient's body ' and then directing an electric fan at the patient are also good ways of cooling. Cool the patient more slowly if he/she starts to shiver since that produces heat. Elevate the patient's head and shoulders slightly during cooling, and make sure that ' he/she is comfortable. • Never give the patient stimulants or hot drinks. ' If proper precautions are taken, heat stroke is completely preventable. Exertion should be limited when temperatures and humidity are high, and activities in direct sunlight should be avoided. Adequate hydration is an absolute necessity and may be the single most important prerequisite for avoiding heat illness. Both fluids and electrolytes should be replaced after any ' activity in the heat; water itself is usually sufficient during exertion. A period of acclimatization is recommended before vigorous activity is undertaken. At least two ' weeks in a hot environment are needed to bring heat control mechanisms to maximum efficiency, and even this period may be inadequate if temperature and exertion are extreme. Heat Exhaustion Heat exhaustion, the most common heat injury, occurs in an otherwise fit person who is involved in extreme physical exertion in a hot, humid environment. This condition results from a serious disturbance of the blood flow, similar to the circulatory disturbance of shock. Heat exhaustion is, in fact, a mild state of shock brought on by the pooling of blood in the vessels ' just below the skin, causing blood to flow away from the major organs of the body. Due to prolonged and profuse sweating, the body loses large quantities of salt and water. When the water is not adequately replaced, blood circulation diminishes, affecting brain, heart, and lung functions. Heat exhaustion is sometimes, though not always, accompanied by heat cramps due ' to salt loss. There are two basic kinds of heat exhaustion. The first is salt depletion (sodium depletion), ' which occurs when un-acclimatized individuals exert themselves and drink enough water but do not replace the sodium. Second, there is water depletion, which occurs when individuals do not 1 ' 902 Industrial Way•Lodi,CA 95240-209.367.3701 •Fax 209.333.8303 02014 Neil O.Anderson&Associates,Inc.
