What does hyperthermia mean?
|
Elevated/ high temperature
|
|
|
What is the difference between hyperthermia and a fever?
|
Fever has a change in the set point. It is caused by infection
|
|
|
Hyperthermia occurs when?
|
The thermoregulatory mechanisms are overwhelmed by: heat production, excessive environmental heat (no ac)
|
|
|
What is heat exhaustion?
|
Decrease in fluid intake and an increase in physical activity and heat exposure
|
|
|
What is heat stroke?
|
Increased body temperature and increased pulse
|
|
|
What is the difference between heat stroke and heat exhaustion?
|
Heat exhaustion skin is wet and moist. Heat stroke skin is dry and hot.
|
|
|
What is hypothermia?
|
A core temperature less then 35*C

|
How do you treat hypothermia?
|
Rewarming
|
|
|
What is core body temperature?
|
The balance between heat gain and heat loss
|
|
|
What is the hypothalamus?
|
Thermal control center
|
|
|
Where does the hypothalamus receive information from?
|
Peripheral thermoreceptors and central thermoreceptors

|
|
What is the normal range of thermoregulation?
|
96.2- 99.4 F Regular- 98.6

|
|
Role of endocrine system in thermoregulation= Hypothalamus receives stimulus -> sends signal to thyroid gland -> sends signal to adrenal medulla to release catecholamines which stimulate...?
|
Vascular changes, skeletal muscle changes, and vascular changes
|
|
|
What is vasodilation?
|
Decrease in temperature. Loose heat/shivering

|
|
What does vasoconstriction do?
|
Prevents blood from surface and keeps heat in the core
|
