Passive Care - Cryotherapy Flashcards
Three things that cryotherapy does
- Vasocontriction
- Anesthesia
- Pumping Reaction
CBAN
Cold (5 minutes)
Burn (10 minutes)
Ache (15 minutes)
Numb (20 minutes)
Hunting Lewis Reaction
Pumping (vasodialation and vasoconstriction) after 20 minutes of icing / bad

Types of Heat Transmission: Convection
transmission of heat in gases and liquids by circulation heat particles
TYPES: Baths (hot and cold), IR
Types of Heat Transmission: Radiation
transmission of heat without the intervening medium getting warm
does not heat air
TYPES: Lamps, MWD, IR, UV
Types of Heat Transmission: Conversion
the conversion of electrical energy into heat or mechanical energy
changes energy, reverse piezoelectric
TYPES: Ultrasound
Types of Heat Transmission: Conduction
the transfer of heat through a substance, often heating up a solid
TYPES: Ice, Hydrocollator, Paraffin, IR
Action of Cryotherapy
Hypothermal
Results of Cryotherapy
LOCAL PRIMARY EFFECTS: decrease edema (vascular), anesthesia (neuro), increase pain tolerance
SECONDARY EFFECTS: increase viscosity of the blood, decrease cell metabolism, increase joint stiffness
Indications of Cryotherapy
Headaches (migraines) Urticaria (red wheals), itchy Spasticity (trigger point) MFS Sprain / Strain Angiomas Warts and Herpes
Contraindications of Cryotherapy
Elderly and Infants Hypersentitive to Cold Vascular Diseases (Raynaud's) High Blood Pressure Chilblains (right before frostbite) and Frostbite Tension Headaches Spasm (fibromyalgia)
Penetration
superficial
