FINALS PT2 Flashcards
Larger area of exposure=
LOWER TOLERANCE
PHYSIOLOGIC RESPONSE TO HEAT
● Vasodilation of peripheral blood vessels
● Increase blood flow (to injured body part)
● Increase supply of oxygen
● Decrease blood viscosity
● Increase tissue metabolism
● Improve circulation
PHYSIOLOGIC RESPONSE TO COLD
● Vasoconstriction of peripheral blood vessels
● Decrease blood circulation
● Decrease capillary permeability
● Delayed re-absorption of fluid
● Increase coagulation of blood
● ↑ Cardiac Output and Pulse Rate
● Sweating
● ↓ Blood Pressure
HEAT
● ↑ Blood Pressure
● Shivering
● Goosebumps
COLD
● Responds to signals from the thermal receptors.
● Controls body temperature.
● Thermoregulatory center in the brain.
HYPOTHALAMUS
Dissipate heat -
Conserve heat -
ANTERIOR HYPOTHALAMUS
POSTERIOR HYPOTHALAMUS
No direct application to skin
common form of dry heat used at home.
HOT WATER BOTTLE OR BAGS
It is a rubber pad of tubular construction that can
be filled with distilled water, an electrical unit
heats the water and keeps it at an even
temperature.
AQUATHERMIA PAD / K PAD
● This provides constant and even heat.
● It has wires that provide heat and should be
covered by rubber or plastic to ensure safety.
ELECTRIC HEATING PAD
It is a gooseneck lamp containing a 60-watt bulb,
applied 18-24 inches from the body.
HEAT LAMP
● Commercially prepared and disposable.
● Instructions depending on the manufacturer.
HOT PACKS
A metal cradle in which several electric sockets are
installed for a 25-watt luminous bulb, applied 18
inches away from the patient.
HEAT CRADLE
● Gel-filled hot packs are available commercially
and are reusable.
● Be certain to read the manufacturer’s
instructions.
GEL-FILLED HOT PACKS
Similar to the waterflow heating pad except that it
is of blanket size.
THERMAL BLANKET
● Deep heat treatment.
● Electrical energy is changed to heat similar to the
principle underlying the microwave.
DIATHERMY
A form of local moist heat application done with
compress cloth.
WARM COMPRESS APPLICATION
Means of applying tepid or hot water to the pelvic
or rectal area. Clients are placed in a tub filled with
sufficient water to reach the umbilicus.
SITZ BATH
Immersion of a body area into warm water or a
medicated solution.
WARM SOAKS
● Filled either with ice chips or with alcohol based
solution.
ICE BAGS/ICE COLLARS/ICE GLOVES
Available commercially and reusable.
GEL-FILLED COLD PACKS
● Commonly referred to as hypothermia blanket.
● The blanket cools the patient to the desired body
temperature and maintains that level.
THERMAL BLANKET (COOLING)
A form of local, moist cold application done with
compress cloth.
COLD COMPRESS APPLICATION
● Used to lower temperature
● Heat dissipates both by heat conduction and
evaporation.
COLD SPONGE BATH
