Flashcards in Chapter 6- Environmental Considerations Deck (27):
1

adapting to an environment

acclimatization

2

exposure to cold; the skin is red and frozen

chilblains

3

this effects the biological time clock

circadian dysrhythmia

4

exposure to extreme cold; the skin is pale and waxy

frostbite

5

there is profuse sweating; excessive thirst

heat exhaustion

6

thermoregulatory failure

heat stroke

7

this brings about headaches, vomiting, and insomnia

mountain sickness

8

sunlight acts on nitrogen dioxide and stagnant air

photochemical haze

9

this measures heat and humidity

WGBT

10

this is caused by a combustion of fossil fuels

smog

11

how is heat eliminated?

conduction
convection
radiation
evaporation

12

factors for swear evaporation

relative humidity
wind velocity

13

for heat thirst; cold drinks, or room temperature drinks?

cold drinks

14

what people are more susceptible to heat illness

women
people who are overweight

15

Symptoms of heat exhaustion

profuse sweating, flushed skin, dizziness, rapid pulse

16

heat exhaustion treatment

cool environment, IV, lots of fluid

17

Heat stroke symptoms

loss of consciousness, almost no sweating, 106.0 degrees or higher

18

heatstroke treatment

straight to hospital, remove clothing

19

how does the body lose heat in the cold

radiation and evaporation

20

superficial vs deep frostbite

superficial effects only the skin, deep goes in more depth (tissues)

21

deep frostbite treatment

rapid warming

22

What causes ozone

sunlight acts on oxygen, nitrogen oxide, and hydrocarbon

23

signs of being in a high ozone environment

shortness of breath, chest tightness, coughing

24

what individuals will suffer from sulfur oxide?

asthmatics

25

steps to prevent heat illness

gradual acclimatization, weight records, eat well, change work uniform, fluid replacement

26

what health conditions are affected by altitude illness?

sickle cell trait
edema
acute mountain sickness

27

How to better adapt to time zone changes

well rester
pre-adjust
drink fluids
avoid caffeine and alcohol
