HYPERTHERMIA - Coggle Diagram
HYPERTHERMIA
Treatment
For Mild Hyperthermia (Heat Exhaustion):
Move to a cooler place: Get out of the heat and into a shaded or air-conditioned area.
Rehydrate: Drink cool fluids like water or sports drinks to replace lost fluids and electrolytes.
Rest: Allow the body time to recover without physical exertion.
Cool the body: Apply cool, damp cloths to the skin or use a fan to help lower the body temperature
For Severe Hyperthermia (Heat Stroke):
Call emergency services immediately: Heat stroke is life-threatening, so fast action is critical.
Cool the body quickly: Move the person to a cool area and begin cooling measures like immersing them in cool (not cold) water or applying ice packs to the neck, armpits, and groin. Avoid using ice or very cold water, as it can cause shock.
Monitor breathing: If the person is unconscious, check for breathing and administer CPR if necessary until help arrives
Types of Hyperthermia
Heat Exhaustion
A milder form of hyperthermia, where the body loses more water and salt than it can replace, causing symptoms like heavy sweating, weakness, dizziness, nausea, and muscle cramps. If left untreated, it can progress to heat stroke
Heat Stroke
The most severe and dangerous form of hyperthermia, it occurs when the body’s core temperature rises above 104°F (40°C). This is a medical emergency and can cause confusion, seizures, loss of consciousness, and organ damage. It requires immediate cooling and medical intervention.
Causes of
heat stroke
CNS Hemorrhage
Malignant hyperthermia
Sepsis/ Bacteremia, CNS infection
thyroid storm
Prevention
stay in a ventilated area and avoid crowded places
Don't try a physical workout in a hot climate
wear lightweight, bright colored, loose-fitting clothes
avoids taking children and aged persons out in hot weather
consume more & more fluids & sports drinks to keep your body hydrated
Pathophysiology
Excessive heat load (environmental or physical) overwhelms the body’s normal cooling mechanisms.
Hypothalamic failure and impaired thermoregulation lead to rising body temperature.
Cellular and organ dysfunction occurs as proteins and enzymes are damaged, leading to a cascade of effects, including electrolyte imbalances, neurological dysfunction, and organ failure
DEFINITION: Hyperthermia is a medical condition where the body’s core temperature rises above the normal range, typically above (38°C), due to the body being unable to dissipate heat effectively.
It can range from mild (heat exhaustion) to severe (heat stroke), with the latter being life-threatening if not treated promptly
Symptoms - blurred vision, dizziness, headache, fatigue/weakness, low blood pressure, fast breathing, muscle aches/cramps, nausea & vomiting
