Chapter 6- Environmental Considerations Flashcards
adapting to an environment
acclimatization
exposure to cold; the skin is red and frozen
chilblains
this effects the biological time clock
circadian dysrhythmia
exposure to extreme cold; the skin is pale and waxy
frostbite
there is profuse sweating; excessive thirst
heat exhaustion
thermoregulatory failure
heat stroke
this brings about headaches, vomiting, and insomnia
mountain sickness
sunlight acts on nitrogen dioxide and stagnant air
photochemical haze
this measures heat and humidity
WGBT
this is caused by a combustion of fossil fuels
smog
how is heat eliminated?
conduction
convection
radiation
evaporation
factors for swear evaporation
relative humidity
wind velocity
for heat thirst; cold drinks, or room temperature drinks?
cold drinks
what people are more susceptible to heat illness
women
people who are overweight
Symptoms of heat exhaustion
profuse sweating, flushed skin, dizziness, rapid pulse
heat exhaustion treatment
cool environment, IV, lots of fluid
Heat stroke symptoms
loss of consciousness, almost no sweating, 106.0 degrees or higher
heatstroke treatment
straight to hospital, remove clothing
how does the body lose heat in the cold
radiation and evaporation
superficial vs deep frostbite
superficial effects only the skin, deep goes in more depth (tissues)
deep frostbite treatment
rapid warming
What causes ozone
sunlight acts on oxygen, nitrogen oxide, and hydrocarbon
signs of being in a high ozone environment
shortness of breath, chest tightness, coughing
what individuals will suffer from sulfur oxide?
asthmatics
steps to prevent heat illness
gradual acclimatization, weight records, eat well, change work uniform, fluid replacement
what health conditions are affected by altitude illness?
sickle cell trait
edema
acute mountain sickness
How to better adapt to time zone changes
well rester
pre-adjust
drink fluids
avoid caffeine and alcohol
