Controls body temperature
Regulates Heat Loss
Regulates Heat Production


Widening of blood vessels that inhibits heat production


Reduces blood flow by narrowing of blood vessels

Heat production occurs through:

Basal Metabolic Rate
Voluntary movement (exercise/activity)
Nonshivering thermogensis (in neonates)

Heat loss occurs through:

Radiation-transfer w/out contact (vasodilation)
Conduction-transfer w/direct contact (hot or cold object)
Convection- transfer w/air movement (fan)
Evaporation-transfer from liquit to gas (sweat)


Controlled by hypothalamus; located between cerebral hemispheres

Skin temperature regulation:

Subcutaneous tissue & fat insulates, keeping heat inside body

Factors affecting body temperature:

newborns- loose up to 30 % heat through head
child-until puberty temp regulation unstable
Elderly-tends to be lower
Hormonal Level-
Woman experience greater fluctuations
Variations during menstrual cycle & menopause

Hot flashes:

Are caused by inability to control vasodilation and vasoconstriction

Exercise increases temperature by:

Stimulating muscle activity, requiring increased blood supply and increased carbohydrate & fat breakdown

Circadian rhythm:

Changes body temperature
Temperature maxes out by 6 pm
Temperature is lowest between 1 -4 am
Can be changed by people working night shift-takes 3 wks


Fever (temperatures above 100.4 / 38 c)

Causes of Pyrexia (fever):

Ambient temperature/humidity
FUO-fever of unknown origin

Fever has the ability to:

Increase Oxygen demands
Increase metabolism
Stress cardiac & respiratory systems
(is an important defense mechanism)

Sustained Fever:

Temp over 100.4 w/ NO fluctuation

Intermittent Fever:

Fluctuation between febrile & afebrile
One afebrile reading in 24 hr period

Remittent Fever:

Fluctuation of temperature but always febrile
No return to afebrile at any time

Relapsing Fever:

Periods of febrile and afebrile temperatures; periods often longer than 24 hrs each

How mild temperatures help immune system:

WBC production is increased, iron concentration is reduced, suppressing growth of bacteria


Temperature over 104 (may go as high as 113)

Malignant Hyperthermia:

Rapid rise in core body temperature that happens when anesthesia is administered;
Caused by hereditary

Heat stroke:

Heat depresses hypothalmic function;

Cold Emergency Management:

Gradual warming, protect injured area, warmed fluids
prevent further heat loss-remove wet cloths, layer clothing, body to body heat

Celsius to Fahrenheit conversion factor:

°C x 9/5 + 32 = °F

Fahrenheit to celsius conversion factor:

(°F - 32) x 5/9 = °C

Axilla temperatures:

Safe for newborns and unconscious


The indicator of circulatory status

What causes the pulse:

Electrical impulses originate in the SA Node and travel to heart muscle to stimulate contraction

Ventricular contraction:

60-70 mL of blood enter aorta

Stroke Volume:

Pulse deficit:

Difference between apical & radial pulse (ineffective contraction)

Irregular rate:

Abnormal accumulation of fluid under skin


Any fluid that filters from the circulatory system into lesions or areas of inflammation.

Primary Intention:

Wound is approximated, clean edges, mainimal risk for infection and scarring

Secondary Intention:

Tissue loss, gaping, irregular wound, epithelium heals over scar; wound is left open until it becomes filled by a scar.

Tertiary intention:

Delayed closure, wide scar; heals from base of wound

Concomitant medical conditions:

Concurrent medical condtions; existing at same time


The use of two or more drugs together, usually to treat a single condition or disease


A restriction in the supply of blood to a body part (ex: tissue) that is due to obstruction of the inflow of arterial blood


Causes damage to the Dermis by stretching and angulation of tissue capillaries
