25 Cards in this Set

  • Front
  • Back
The presence of air in the veins, which can lead to cardiac arrest if it enters the heart.
air embolism
The temperature of the surrounding environment.
ambient temperature
A serum that counteracts the effect of venom from an animal or insect.
antivenin
Common name for decompression sickness.
bends
Loss of consciousness caused by a decreased breathing stimulus.
breath-holding syncope
The loss of heat by direct contact (eg, when a body part comes into contact with a colder object).
conduction
The loss of body heat caused by air movement (eg, breeze blowing across the body).
convection
The temperature of the central part of the body (eg, the heart, lungs, and vital organs).
core temperature
A painful condition seen in divers who ascend too quickly, in which gas, especially nitrogen, forms bubbles in blood vessels and other tissues; also called "the bends."
decompression sickness
Slowing of the heart rate caused by submersion in cold water.
diving reflex
The process of experiencing respiratory impairment from submersion or immersion in liquid.
drowning
Any signs and symptoms caused by the difference between the surrounding atmospheric pressure and the total gas pressure in various tissues, fluids, and cavities of the body
dysbarism injuries
Conversion of water or another fluid from a liquid to a gas.
evaporation
Damage to tissues as the result of exposure to cold; frozen or partially frozen body parts are frostbitten.
frostbite
Painful muscle spasms usually associated with vigorous activity in a hot environment
heat cramps
A form of heat injury in which the body loses significant amounts of fluid and electrolytes because of heavy sweating; also called heat prostration or heat collapse.
heat exhaustion
A life-threatening condition of severe hyperthermia caused by exposure to excessive natural or artificial heat, marked by warm, dry skin; severely altered mental status; and often irreversible coma.
heatstroke
A family of insects that includes bees, wasps, ants, and yellow jackets.
hymenoptera
A condition in which the body core temperature rises to 101°F (38.3°C) or more.
hyperthermia
A condition in which the internal body temperature falls below 95°F (35°C), usually as a result of prolonged exposure to cool or freezing temperatures.
hypothermia
The transfer of heat to colder objects in the environment by radiant energy, for example heat gain from a fire.
radiation
The process of exchanging oxygen and carbon dioxide.
respiration
A triage process in which efforts are focused on those who are in respiratory and cardiac arrest, and different from conventional triage where such patients would be classified as deceased. Used in triaging multiple victims of a lightning strike.
reverse triage
A system that delivers air to the mouth and lungs at various atmospheric pressures, increasing with the depth of the dive; stands for self-contained underwater breathing apparatus.
SCUBA
The ability of the skin to resist deformation; tested by gently pinching skin on the forehead or back of the hand.
turgor
