Body Thermostat
This is the temp in the trunk of the body comprising of the heart, lungs, brain, and abdominal viscera.
What is Core Body Temp?
This is the relaease of stored heat and energy from the body.
What is thermolysis?
These are at least two of the factors that increase internal heat production.
What is exertion, fever, agitation, and drug overdoses?
This type of heatstroke affects the extremes in age, people with decreased mobility, and people living in poorly ventilated areas.
What is a classic heatstroke?
This is a decrease in CBT starting at 95F.
What is hypothermia?
Due to its ability to fluctuate, temps in this part of the body play a major role in thermoregulation.
What is the skin and extremities or periphery?
This method of heat loss is used instinctively when we blow on food to cool it off.
What is convection?
This is the presentation of the skin in heat exhaustion.
What is cool, moist skin?
This type of heatstroke is more common in younger, healthier people.
What is an exertional heatstroke?
The loss of this skin layer contributes to hypothermia in geriatric patients.
What is subcutaneous tissue?
This is the organ responsible for thermoregulation.
What is the hypothalamus?
This method of heat loss accounts for more than 65% of bodily heat loss.
What is radiation?
This symptom may be present or absent in heat exhaustion.
What are muscle cramps?
Along with AMS, this diagnostic vital sign is used to determine a heatstroke, though its absence does not rule out a heatstroke.
What is a temp of 104 or greater?
This is a major contributor to hypothermia in infants.
What is large head to body surface area?
This is the most important factor in heat loss to the environment.
What is body surface area?
This method of heat loss explains why trauma patients on the ground continue to lose heat even after being covered up.
What is conduction?
This is the main cause of heat cramps.
What is sodium and water loss?
Though these prostaglandin blocking agents can be used to decrease a fever, they should not be used to treat heat illnesses.
What are NSAIDS and ASA?
These are at least four of the factors that contribute to hypothermia in the general population.
What is alcohol use, liver disease, diabetic neuropathy, spinal cord injury, wet clothes, wind chill, and meds that interfere with vasoconstriction.
This is the heat energy produced at rest from normal metabolic reactions.
What is the basal metabolic rate?
An increase in CBT causes the hypothalamus to activate this system and induce vasodilation and sweating.
What is the autonomic nervous system?
These three factors contribute to water depleted heat exhaustion in geriatric patients.
What are diuretic meds, decrease thirst sensitivity, and increased immobility?
This drug can induce malignant hypothermia and should be closely monitored.
What is Succinylcholine?
Hypothermia in trauma patients contributes to these two deadly conditions.
What is coagulopathy and acidosis?
