Week 2: Ch. 7 (Thermal Agents: Heat) Flashcards
1
Q
Superficial Agents
A
- Skin
- Subcutaneous Tissue
2
Q
Deep Heating Agents
A
- Large muscles
- Periarticular structures
3
Q
Periarticular
A
- around a joint of the body
4
Q
Heat Agents
A
transfer heat to the body
5
Q
Cool Agents
A
transfer heat away from the body
6
Q
Specific Heat
A
- amount of energy required to raise temperature
- Skin: 3.77 J/gm/C
- Muscle 3.75 J/gm/C
7
Q
Conduction Transfer
A
- Direct contact due to direct collision
- agent to body
- body to agent
- Skin will heat more than deeper structures
8
Q
Convection Transfer
A
- Direct contact with a circulating medium
- e.g. Whirlpool /Fluidotherapy
- Decreases risk of burns
9
Q
Conversion Transfer
A
- Non-thermal Energy converted to heat
- e.g. Ultrasound/Diathermy
10
Q
Radiation Transfer
A
- Direct Transfer (hight temp to low temp)
- No Medium/Contact used
- e.g. Infrared Lamp
11
Q
Evaporation Transfer
A
- Liquid to Gas
- e.g. Vapocollant/Sweating
12
Q
Hot Packs
A
- 6-8 layers (Top)
- 8-10 layers (Underneath)
- Folded towel = +2 layers
- 20 min. Tx (Check within 5 min.)
13
Q
Paraffin Application
A
- Dip 6-10 x’s
- allow to harden within dips
- 10-15 min. Tx
- Wrap in a plastic bag + mitten
14
Q
Fluidotherapy Application
A
patient may move or Ex
* 20 min Tx.
15
Q
Superficial Heat Uses
A
- immdiately perform stretching
- Increase ROM/circulation
- Decrease joint stiffness
- enymatic activity + oxygen
