conduction
The loss of body heat caused by air movement
convection
The temperature of the central part of the body
core temperature
A painful condition in divers who ascend too quickly, and which gas, especially nitrogen, forms bubbles in blood vessels and other tissues
decompression sickness
The slowing of the heart rate caused by submerging in Coldwater
diving reflex
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 and various tissues, fluids, and cavities of the body
Dysbarism injuries
Conversion of water or another liquid to gas
evaporation
Damage to the tissues as the result of exposure to cold; frozen body parts
frostbite
A condition in which the body core temperature falls below 95°F or 35°C after exposure to a cold environment
hypothermia
Painful muscle spasms usually associated with vigorous activity in a hot environment
heat cramps
A life threatening condition of severe hypothermia caused by exposure to excessive natural or artificial heat, marked by warm, dry skin; severely altered mental status; and often a reversible,
heat stroke
A balance of all the systems of the body
Homeostasis
A condition in which the body core temperature rises to 101°F or 38.3°C or more
hyperthermia
A family of insects that includes bees, wasps, ants, and yellow jackets
Hymenoptera
The transfer of heat to colder objects in the environment by radiant energy; for example heat gained from the fire
radiation
The loss of body heat as warm air in the lungs is exhaled into the atmosphere and cooler air is inhaled
respiration
A triage process used in treating multiple victims of a lightning strike, in which efforts are focused on those who are in respiratory and cardiac arrest. Reverse triage is different from conventional triage were such patients would be classified as deceased
reverse triage
The system that delivers air to the mouth and lungs at various atmospheric pressure's, increasing with the depth of the dive; stands for self contained underwater breathing apparatus
scuba gear
The ability of the skin to resist deformation; tested by gently pinching skin on the forehead or back of the hand
turgor
