Dr. Susan Yeargin’s course on exertional heat illnesses covers exercise-associated muscle cramps, Exertional Heat Exhaustion, Sickling, and Exertional Heat Stroke. It is designed to highlight key items in each of the following domains for both the experienced and novice health care clinician. Etiology along with clinical history items is provided for the recognition of each condition followed by immediate evidence-based treatments. Known risk factors are presented in conjunction with prevention interventions for each condition. Lastly, general guidelines for return to activity are given. Throughout the course, common mythology is addressed, research support provided, and practical applications offered.

Outline the basic treatment course for exertional heat exhaustion and syncope patients. Recommend prevention strategies for exertional heat exhaustion.
Differentiate between exertional and classical heat stroke definitions. Explain the physiological etiology of exertional heat stroke. Compare the key signs and symptoms associated with exertional heat stroke as opposed to exertional heat exhaustion. Judge exertional heat stroke treatment options to determine the best patient outcome. Propose prevention strategies based on the predisposing factors associated with exertional heat stroke.
