- A serum that counteracts the effect of venom from an animal or insect.
- Common name for decompression sickness.
- Slow heart rate, less than 60 beats/min.
breath-holding syncope -
- Loss of consciousness caused by a decreased breathing stimulus.
- The loss of heat by direct contact (eg, when a body part comes into contact with a colder object).
- The loss of body heat caused by air movement (eg, breeze blowing across the body).
core temperature -
- The temperature of the central part of the body (eg, the heart, lungs, and vital organs).
decompression sickness -
- 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."
-- Slowing of the heart rate caused by submersion in cold water.
-- Death from suffocation by submersion in water.
- Certain salts and other chemicals that are dissolved in body fluids and cells.
- Conversion of water or another fluid from a liquid to a gas.
- Damage to tissues as the result of exposure to cold; frozen or partially frozen body parts.
heat cramps -
- Painful muscle spasms usually associated with vigorous activity in a hot environment
heat exhaustion -
- 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.
- 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.
hyperbaric chamber -
- A chamber, usually a small room, pressurized to more than atmospheric pressure.
- A condition in which core temperature rises to 101 degrees F (38.3 degrees C) or more.
- A condition in which the internal body temperature falls below 95 degrees F (35 degrees C) after exposure to a cold environment.
- Spasm of the larynx and surrounding structures.
near drowning -
- Survival for 24 hours , at least temporarily, after suffocation in water.
- The transfer of heat to colder objects in the environment by radiant energy, for example heat gain from a fire.
- The loss of body heat as warm air in the lungs is exhaled into the atmosphere and cooler air is inhaled.
reverse triage -
- 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.
- 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.
- The ability of the skin to resist deformation; tested by gently pinching skin on the forehead or back of the hand.
