Dictionary » H » Hyperthermia




A condition in which the body temperature is higher than the normal range


Hyperthermia pertains to a condition in which the body temperature is higher than the normal range. In humans, the body temperature that is regarded as normal is around 37 °C or 98.6 °F (measured by an oral thermometer). Body temperature that is higher than that range is considered hypothermia. Essentially, the hypothalamus regulates the body temperature such that when the surroundings is too hot it tells the body to dissipate the heat, especially when the body absorbs more heat than it dissipates. When the heat-regulatory mechanisms of the body fail to do so the body temperature raises and exceeds the normal. In certain literature, the trigger of hyperthermia is limited to an external source, particularly the heat coming from the environment.1, 2 In other literature, hyperthermia is also regarded to be triggered by an internal factor such as when the immune system fights off an infection. Thus, it is used sometimes as a synonym for hyperpyrexia.

Word origin: Greek huper (over) + Greek therme (heat)

... Hence, while giving ice bath treatment, the client's body temperature has to be monitored closely. We don't want someone that comes in with hyperthermia turns into hypothermia. :wink: Good luck.

Homeostatic control o core body temperture

So do you get to choose the condition? I'd choose Malignant Hyperthermia :D They're just asking you 1. How does the body thermoregulate 2. Describe the pathophysiology of thermoregulation (or lack therof) in a specific condition

Calcium and Muscle fibers

when Ca++ can't be pumped back to sarcoplasmic reticulum, it will ultimately result in malignant hyperthermia. the process is as following: 1. In ACTIN thin filament, Ca++ stimulates troponin to pull tropomyosin away from the myosin binding site (tropomyosin normaly 'covers' ...
