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
Treatment Temperatures: Cold
55-65
Treatment Temperatures: Cool
65-80
Treatment Temperatures: Tepid
80-92
Treatment Temperatures: Neutral
92-96
Treatment Temperatures: Warm
96-99
Treatment Temperatures: Hot
99-104
Treatment Temperatures: Very Hot
105-115
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
Dosage
Every 20 minutes, each two waking hours
Types: Ice Pack
Moist towel layer - increase ice permeability
Time: 20 minutes
Method: conduct
Types: Blue Ice
Dry towel layer, reusable
Time: 20 minutes
Method: conduct
Types: Vapocoolant Spray
Fluori-methane / Ethyl chloride
18-24”, angle spray, spray one direction, nozzle adjusts
Time: none
Method: none
it’s not used a lot anymore - bad for the ozone
Types: Ice Massage
Direct ice has deepest effect / Must move
Time: 0 - 20 minutes
Method: Conduct
