Q

Conduction

A
  • refers to the gain or loss of heat resulting from direct contact between two materials at different temp
  • heat is conducted from a material of higher temp to one of lower temp. heat transfer cont. until the temp and speed of molecular movement of both materials become equal

-EX: hot pack, cold pack, paraffin, ice massage and cryo cuff

Q

Convection

A
  • gain or loss of heat resulting from air or water moving in a constant motion across the body. Since the thermal agent is in motion and new parts of the agent are constantly coming into contact with the target area, heating by convection is capable of transferring large amounts of heat
  • EX: fluidotherapy, hot whirlpool, cold whirlpool

Q

Conversion

A
  • refers to heating that occurs when nonthermal energy is absorbed into tissue and transformed into heat
  • the rate of heat transfer with conversion is determined by the power of the energy source
  • Heat transfer does not require direct contact between the thermal agent and the target areas, however, it does require a medium that allows transmission of the particular type of energy
  • In the case of US, the medium may be gel, lotion or water
  • EX: diathermy and US

Evaporation

A
  • refers to the transfer of heat that occurs as a liquid absorbs energy and changes form into a vapor
  • in the case of a vapocoolant spray, the liquid spray is applied to a patient’s body
  • the vapocoolant spray is then heated by the warmer skin of the body, causing the liquid to change into vapor

Q

Radiation

A
  • refers to the direct transfer of heat from a radiation energy source of higher temp to one of cooler temp
  • in order for heating by radiation to occur, there must be a difference in temp between the energy source and the target area
  • this difference must exist without the energy source being in direct contact with the target area
  • the rate of heat transfer will be influenced by a number of factors including the intensity and size of the energy source, the target area, the angle of the radiation in relation to the target area, and the distance between the energy source and the target area
  • Ex: infrared lamp, laser, UV light
