Flashcards in Environmental Emergencies Deck (21):
1

Conduction

transfer of heat from one material to another through direct contact

2

water chill

chilling caused by conduction of heat from the body when the body or clothing is wet
water conducts heat away from the body 25 times faster than still air

3

Convection

carrying away of heat by currents of air, water, or other gases or liquids

4

Wind Chill

chilling caused by convection of heat from the body in the presence of air currents

5

Radiation

body's atoms and molecules send out rays of heat as they move and change
most occurs in head and neck

6

evaporation

change from liquid to gas. when the body perspires or gets wet evaporation of the perspiration or other liquid into the air has a cooling effect on the body

7

Respiration

breathing. during respiration, body heat is lost as warm air is exhaled from the body

8

Hypothermia

generalized cooling that reduces body temperature below normal, which is a life-threatening conditions in its extreme

9

Passive rewarming

converting a hypothermic patient and taking other steps to prevent further heat loss and help the body rewarm itself

10

Active rewarming

application of an external heat source to rewarm the body of a hypothermic patient

11

Central Rewarming

application of heat to the lateral chest, neck, armpits, and groin of a hypothermic patient

12

Local cooling

cooling or freezing of particular (local) parts of the body

13

Hyperthermia

an increase in body temperature above normal, which is a life-threatening condition in its extreme

14

drowning

process of experiencing respiratory impairment from submersion/immersion in liquid. which may result in death, morbidity (illness or other adverse effects), or no morbidity

15

air embolism

gas bubble in the bloodstream. the plural is air emboli. the more accurate term is arterial gas embolism (AGE)
Signs and Symptoms: blurred vision, chest pain, numbness and tingling sensation in the extremities, generalized or specific weakness, possible paralysis, frothy blood in the mouth or nose, convulsions, rapid lapse into unconsciousness, respiratory arrest and cardiac arrest

16

decompression sickness

condition resulting from nitrogen trapped in the body's tissues, caused by coming up too quickly from a deep, prolonged dive. symptom of decompression sickness is "the bends" or deep pain in the muscles and joints
Signs and Symptoms: Personality changes, fatigue, deep pain to the muscles and joints ("bends"), itchy blotches or mottling of the skin, numbness or paralysis, choking, coughing, labored breathing, behavior similar to intoxication, chest pains, collapse leading to unconsiousness

17

Emergency care for AGE or Decompression sickness

Maintain an open airway
administer high concentration O2
Rapid transport
take to Hyperbaric Trauma care center
Keep Patient warm
position either supine or either side

18

Diver Alert Network (DAN)

assist rescuers with the care of underwater diving accident patients
(919) 684-8111
for nonemergencies (919) 684-2948

19

Water Rescue Precedure

Reach, Throw, Row, Go

20

Toxins

Substances produced by animals or plants that are poisonous to humans

21

Venom

toxin (poison) produced by certain animals such as snakes, spiders, and some marine life forms.
