| Air Embolism | Air bubbles in the blood vessels. |
| Ambient Temperature | The temperature of the surrounding environment. |
| Anitvenin | A serum that counteracts the effect of venom from animals or insects. |
| Bends | Common name for decompression sickness. |
| Breath Holding Syncope | Loss of consciousness caused by decreased breathing stimulus. |
| Conduction | Loss of heat through direct contact (eg, when the body comes in contact with a colder object). |
| Convection | 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, the lungs, and vital organs). |
| Decompression Sickness | A painful condition seen in divers who ascend too quickly, in which gas, especially notrogen, forms bubbles in the blood vessels and tissues; also called "the bends". |
| Diving Reflex | Slowing of the heart rate caused by submersion in colder water. |
| Drowning | The process of experiencing respiratory impairment from submersion or immersion in liquid. |
| Evaporation | Conversion of water or another fluid from a liquid to a gas. |
| Frostbite | Damage to tisues as a result of exposure to cold; 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. |
| Heat Stroke | 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. |
| Turgor | The ability of the skin to resist deformation; tested by gently pinching skin on the forehead or back of the hand. |
| Hyperthermia | A condition in which the body core temperature rises above 101 degrees F (38.3 C) or more. |
| Hypothermia | A condition in which the body core temperature falls below 95 degrees F (35 C) after exposure to a cold environment. |
| Respiration | The loss of body heat as warm air in the lungs is exhaled into the atmosphere and cooler air is inhaled. |
| Radiation | The transfer of heat to colder objects in the environment by radiant energy, for example heat gain from a fire. |
| Hymenoptera | A family of insects that includes bees, wasps, ants, and yellow jackets. |
| Reverse Triage | A 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. |
| SCUBA | A system that delivers air to the mouth and lungs nat various atmospheric pressures, increasing with the depth of the dive; and stands for "self contsained underwater breathing apparatus. |
