An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.
Heat illness is a spectrum of disorders due to increased body temperature. It can be caused by either environmental conditions or by exertion. It includes minor conditions such as heat cramps, heat syncope, and heat exhaustion as well as the more severe condition known as heat stroke. [1] It can affect any or all anatomical systems. [2]
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness. Heat stroke is more likely than heat exhaustion to cause palor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of spatial awareness, loss of bodily movement control, seizures, etc.).
Heat exhaustion: Heat exhaustion is the body's response to an excessive loss of water and salt that usually happens from sweating a lot, according to the CDC. It can cause heavy sweating, fatigue ...
The National Association of EMS Officials recommends "Cool First, Transport Second" for patients whose body temperature is over 104 degrees.
[1] [11] Later research revealed the link between neurological signs such as visual loss and increased heat production and Uhthoff's belief that exercise was the etiology of visual loss was replaced by the conclusions of these later researchers stating that heat was the prime etiology.
The resulting increase in calcium concentrations within the cells cause the muscle fibers to contract. [1] This generates excessive heat and results in metabolic acidosis. [1] Diagnosis is based on symptoms in the appropriate situation. [2] Family members may be tested to see if they are susceptible by muscle biopsy or genetic testing. [4]
