  • Dizziness

  • Headache

  • Brief fainting (passing out)

What happens to the body when Hypothermia occurs?

Hypothermia can lead to complete failure to the heart and respiratory failure leading to death.

100

What is the first step in caring for heatstroke and hypothermia?

Call 911 right away.

100

What is the main sign of a heatstroke?

Core temperature of 104 or greater.

200

What beverages are off-limits when treating a patient for heatstroke?

ALL OF THEM. Do not give them anything to drink.

200

Does Hypothermia increase the heart rate?

Yes, it causes the blood vessels and arteries to narrow, restricting blood flow and reducing oxygen to the heart.

200
What part of the body do you warm first in Hypothermia?

Warm the core first (trunk, abdomen), not the extremities (hands, feet). Most people will try to warm hands and feet first and that may cause shock.

200

What is the coldest core temperature a human can survive?

The average body temperature is 98.6 degrees Fahrenheit. At an internal temperature of 95 degrees, humans can experience hypothermia, shivering, and pale skin. At 86 degrees, they become unconscious and, at 77 degrees, cardiac arrest can occur. Most people cannot survive if their core temperature drops to 75 degrees.

300

Why shouldn't you heat up victims of Hypothermia too quickly?

Rapid warming may cause dangerous heart arrhythmias.

300

Why does frostbite turn your skin black?

After re-warming the area, the skin will appear black and feel hard due to tissue death in the affected area.

300

What are the steps (in order) for caring for Heatstroke victims?

1. Call 911
2. Move the person to a cooler place
3. Help lower the person's temperature
4. Do not give the person anything to drink

300

What is the hottest core temperature a human can survive? 

The maximum core temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably.

400

What is a symptom of frostbite?

  • Reduced blood flow to hands and feet (fingers or toes can freeze)

  • Numbness

  • Tingling or stinging

  • Aching

  • Bluish or pale, waxy skin

400

Why do some people faint while having a heat stroke?

Some people faint, because blood flow and oxygen to the brain slow down.

400

What is the last step in caring for heat exhaustion?

Have the person sip water.

400

How long does it take to recover from heatstroke?

The initial recovery is 1-2 days, complete recovery is 2 months to a year.
