Cryotherapy Flashcards
The primary effect of cold on the body is _____
Vasoconstriction
Intensely itchy hives or rash due to a physical allergy to cold is called ____
Cold urticaria
Blood contains cold coagulable globulin. May see in multiple myeloma, among other diseases
Cryoglobulinemia
This syndrome occurs when parts of the body (usually fingers, toes, ears, nose) feel numb and cool in response to cold temperatures or stress. It’s often accompanied by changes in color of the skin (white, blue)
Raynaud’s phenomenon
Name the test: scratch the forearm with a pointed object. Normally and white line occurs and within 10 seconds it turns to a red line. If the line stays white it is a positive test
Barch test
The speed of a nerve impulse is ____ (increased/decreased) with decreased tissue temperatures
Decreased
T/F: Rheumatoid or gouty arthritis are contraindications the cryotherapy
TRUE
What are the 3 methods of cooling?
- Conduction
- Convection
- Evaporation
Name the method of cooling: heat is transferred between a surface and a fluid (liquid or gas) which is moving over the surface. This transfers heat faster than if the liquid is not moving
Convection
As a substance goes from a liquid to a solid state, it requires heat which is taken from the surrounding area. This is called _____
Evaporation
____ is when heat is transferred when two bodies of different temperatures are in contact.
Conduction
Heat is conducted from the hot material to the cool material. Good conductors are generally hard, dense materials. What type of cryotherapy would fall in this category?
Ice packs (conduction)
Wind chill, ice baths, and fluidotherapy fall in this category of cooling.
Convection
____ cools the body by evaporating and thus removing heat.
Sweat
When doing ice massage, an area about __ inches in diameter is covered over a 10-15 minute period.

List the 4 stages of cold:
- Coolness
- Burning
- Aching
- Numbness
Cold packs should be used for __-__ minutes
20-30
___ produce cooling through the rapid evaporation of a hydrocarbon applied to the skin.
Vapocoolants
Ethyl Chloride and Fluori-methane are two kinds of _______
Vapocoolants
Water temperature in ice baths should be __-__ F, submerge area to be treated for 10-20 minutes.
55-64 degrees
A _____ consists of a wrap that goes around the affected joint. It is attached to a small cooler filled with ice and water. When the cooler is placed above the wrap, cold water flows into the wrap cooling it and expanding it causing compression of the area also.
Cryo-Cuff
_____ helps reduce edema through a pumping action of the tissues.
Alternating heat and cold
____ reaction is periods of intermittent vasodilation and vasoconstriction following 15-30 minutes of vasoconstriction.
