Study Notes
Dehydration
- A hallmark of dehydration is excessive thirst.
- A 5-8% decrease in total body water can cause impaired physical performance.
- Chronic dehydration can lead to kidney stones as a potential consequence.
- Dehydration is distinguished from hypovolemia by the loss of water and electrolytes, whereas hypovolemia is a loss of blood volume.
Hypothermia
- Death occurs when 12-15% of total body water is lost.
- Symptoms of moderate hypothermia include confusion, disorientation, and stumbling.
- A common cause of hypothermia besides exposure to cold weather is prolonged immersion in water.
- Hypothermia is diagnosed by a low body temperature, typically below 95°F (35°C).
- The recommended treatment for mild hypothermia is to remove wet clothing and provide warm, dry clothing and a warm drink.
- Paradoxical undressing, where a person removes their clothing, is associated with severe hypothermia.
