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
Common name for decompression sickness.
A heart rate of less than 60 beats/min in children or less than 80 beats/min in infants.
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).
The loss of body heat caused by air movement (eg, breeze blowing across the body).
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
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.
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

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.
A severe constriction of the larynx and vocal cords.
Survival, at least temporarily, after suffocation in water.
near drowning
