-
General weakness, lethargy, and cognitive changes following rapid ascent to a high altitude.
Acute Mountain Sickness (AMS)
-
Transfer of heat (including the air) in direct contact with the body.
Conduction
-
Transfer of air through the movement of air currents
Convection
-
Respiratory impairment from submersion or immersion in a liquid medium
Drowning
-
Loss of heat when moisture vaporizes on the body's surface
Evaporation
-
Injury to the skin caused by prolonged exposure to the cold; Liquid content of the skin cells feezes; may be superficial or deep
Frostbite
-
Completely reversible superficial cold injury caused by intense vasoconstriction that affects only the topmost portions of the skin
Frostnip
-
Cerebral edema followinga rapid ascent to a high altitude
High-Altitude cerebral edema (HACE)
-
Pulmonary edema following a rapid ascent to a high altitude
High-altitude pulmonary edema (HAPE)
-
Abnormal and dangerous condition in which the body temperature falls below 95 degrees F (35 degrees C) and the body's normal body functions are impaired; usually caused by prolonged exposure to cold
Hypothermia
-
Transfer of heat by infrared heat rays. Heat rays are radiated by the body and other objects in the environment. If the temperature of the body is greater than the temperature of the surroundings, heat is lost from the body
Radiation
-
Any submersion into water that requires field care and transport to a hospital for treatment or observation
Submersion episode
-
The metabolic activity necessary to maintain cellular functions at rest
Basal Metabolism
-
The involuntary contraction of small groups of muscles, which can generate great amounts of heat
Shivering
-
A red rash with small bumps, usually found at the neck, under arms, and in the groin, caused by blocked sweat glands
Heat Rash
-
Muscular cramps that occur during strenuous exertion and from excessive loss of body fluid through persperation
Heat cramps
-
Inability of the cardiovascular system to keep up with stresses imposed by a hot environment. Rarely causes death
Heat Exhaustion
-
A transient loss of consciousness resulting from the blood vessels dilating to compensate fir excessive heat
Heat Syncope
-
A complete failure of the thermoregulatory system that results in extreme increases in core body temperature and damage to cells as well as changes to mentation. Associated with a high mortality rate
Heat Stroke
-
Inhibits heat loss because of the increased insulating effect of the excess subcontaneous fat
Obesity
-
Constant muscle tremors, and increased heat production, is another condition that predisposes an individual to heat illness
Parkinson's Disease
-
Fall in blood pressure when the supine patient stands
Orthostatic Hypotension
-
The most severe reaction to bug bites/stings
Anaphylaxis
-
Unpleasant tingling feelings both at the site of envenomation and at distant sites
Paresthesias
-
This snake's bite causes local necrosis; in severe cases, systemic effects occur and death may result. Dent between eyes and nostril, and plates on tail. Other symptoms of this snake bite are: Swelling, pain, redness of site
Pit Viper
-
This snake's bite causes no local necrosis. The nervous system is affected when the poison is obsorbed. The onset of effects may be delayed for up to 12 hours. Systemic effects can lead to respiratory paralysis and death. Skin colors are, red-yellow-red. Early signs of bite are mild, usually only minimal redness, and swelling.
Coral Snake
-
Generalized term used to describe the physiologic changes seen when a person is exposed to pressure changes.
Dysbarism
