Heat Flashcards
(20 cards)
Used for chronic injury
It has been used for centuries for relieving pain & ⬇️Ms. Spasm
Heat
Heating
Therapeutic effects of Heat:
- Pain relief
- ⬆️ Blood Flow
- fascilitate tissue healing
- ⬇️ Ms. Spasm
- Prepare stiff joints & tight ms. for exercise
Superficial and Deep Modalities
Superficial:
- HMP
- Paraffin Wax
- Fluidotherapy
Deep:
- Continuous Short Wave diathermy
- Continuous Wave US
Superficial Modalities
- To heal superficial joints.
- Cause a heating effects in deeper structures.
- Heat soft tissue in order to ⬆️ its extensibility.
What is the therapeutic level of heat?
40C - 45C / 104F - 113F
What is the Biophysical effects of temp. Elevation?
- Extent of the temp rise
- Rate of which energy is being added to the tissue
- Volume of Tissue exposed
- Composition of the absorbing tissue
- Capacity of the tissue to dissipate it.
It is a specialized blood vessel that can dissipate heat?
Arteriovenous Anastomoses
What are the thermal modality options of Heat?
- HMP
- PWB
- Fluidotherapy
- Warm Whirlpool
- Microwavable Gel Packs
- Air activated Heat wraps
- Electric Heating wraps
What is the Physical Principle of Heat?
Thermal Conductivity = Heat flow through tissues that varies c the nature of the type of tissue.
In thermal conductivity how long will be the exposure of the skin if it is 0.5 - 2.0 cm and the 1-2cm?
0.5 - 2.0cm = 6-8 mins
1-2cm = 15 - 30 mins
Heat Transfer:
Conduction - Direct Contact
Convection - Liquid
Evaporation - Travels in waves
in HMP what are the sizes?
Standard = 10 x 12”
Half-size = 5 x 12”
Cervical = 24 x 6.5”
Lumbar = 24 x 15”
Jumbo = 24 x 30”
Spinal = 10 x 18”
What is the 3 things that makes the paraffin wax efficient?
What is the low melting point of Paraffin Wax?
What is the self sterilizing point?
- Low Melting Point
- 54C / 129F (50C-55C) - Low specific Heat
- Conducts heat more slowly than water
Sterilizing point = 60C - 65C
The techniques of Paraffin wax:
- Dip & Wrap
- Dip & re-immerse
- Pouring
- Brushing
What is the ration of paraffin wax?
7:1
Wax:oil
Contraindication
- Acute injury
- Impaired Sensation
- DVT
- Very young / very old
- Heat tolerance
- Malignancy
A method of applying low level heat over a long time
Electric Heating Pads
A dry heat modality that transfers heat through forced convection
Fluidotherapy
What are the multiple disc?
- iron powder
- activated charcoal
- Sodium chloride
- water
Indications of heating modalities
- chronic injury
- pain
- lack of tissue extensibility
- Ms. Spasm & Guarding
