The flashcards below were created by user BPT on FreezingBlue Flashcards. What would you like to do?


  1. how deep can superficial heat penetrated?
    1-10 mm
  2. What does superficial heat do?
    • increases metabolic rate of cellular processes
    • enhances inflammatory response
    • inhibits sympathetic nerve stimulation, causing vasodialation
  3. Why is it good to get the skin warm with superficial heating?
    increases blood flow and nerve endings are there so can cut out pain sensation for temporary amount of time
  4. what are some of the physiological effects of superficial heat
    • increase metabolism (direct)
    • increase blood flow (direct and reflex)
    • increase elasticity (direct)
    • produces relaxation (reflex)
    • decreases muscle strength (reflex)
    • decreases pain (reflex)
  5. what are the therapeutic benefits of superficial heat
    • decreased pain
    • increased range of motion
    • increased healing rate
  6. name some of the ways a heat is transferred
    • conduction
    • convection
    • radiation
  7. what is convection
    convection is circulation of the media such as air or water
  8. what is conduction
    transfer heat from one surface to another through direct contact
  9. what is an example of radiation
    heat absorbed from the sun
  10. when using a hotpack, what type of heat transfer is being used
    radiation and conduction (slow release of thermal energy)
  11. what is the temperature of the water in the hydrocollator?
    170°F
  12. how long does a typical hotpack treatment last
    about 30 min.
  13. how many layers should be used on a hotpack
    six layers of towels
  14. explain how to apply it hotpack
    • inspect skin
    • remove pack from tank with tongs
    • insulate pack with covers/towels
    • protect clothes/sheets from moisture
    • leave pack on for 20 – 30 min.
    • check skin at the end
  15. after applying a hot pack, you should always check the skin for capillary refill. What does it mean if you check the capillary fill and the skin remains red?
    it means you burnt the patient and you need to tell them.

    Be sure to ask if the skin is itchy
  16. What don't you want to heat with a hot pack?
    • large scars
    • poison ivy
    • burns
    • wounds
  17. how long does a typical paraffin bath treatment lasts?
    10 to 15 min.
  18. what is the temperature of a paraffin bath
    130°F
  19. What type of heat transfer is a paraffin bath?
    conduction
  20. how do you perform a paraffin bath treatment – name the steps
    • inspect and wash skin, no jewelry
    • dip body part 6 – 12 times
    • Place body part in bag, wrap in towel
    • peel off wax after 10 min.
    • discard or return wax to bath
  21. true or false – when performing a paraffin Bath treatment, there will be a small space between the hand and the wax
    true
  22. when performing a paraffin bath treatment, the patient may say "the wax isn't hot anymore", when in reality it still is, explain this
    the Thermo receptors in the skin become accustomed the sensory input ( steady-state)
  23. what are the two methods of performing a paraffin bath treatment
    • dip – remove – wrap
    • dip – remove – leave
  24. why doesn't paraffin at 130°F burn the skin
    specific heat
  25. what method of heat transfer is used when performing an infrared lamp treatment
    radiant heat
  26. true or false – infra-red lamps have a lightbulb that is 500 W
    true
  27. why do infra-red lamps have red light bulbs
    to soften the glare of the lamps
  28. explain the technique of using infrared lamps
    • inspect skin
    • lamp is at 90° and 45 – 60 cm away
    • avoid directing into eyes
    • treatment last 15 to 30 min.
    • check skin for blanching
    • remove light and inspect skin
  29. when performing an infrared lamp treatment, what happens if you decrease the distance from the body and the lamp by one half
    the energy/heat absorbed by the body will quadruple
  30. fluidotherapy involves what type of heat transfer
    • conduction (touch the skin)
    • convection (move past the skin)
    • radiation (coil at bottom)
  31. true or false – you can't use fluidotherapy if you have an open wound
    false

    Yes you can but the wound must be covered
  32. how hot does fluidotherapy get
    102 – 118°F
  33. What is fluidotherapy (general)?
    heated air blowing into cellulose particles (corn cob particles)
  34. explain the treatment techniques for fluidotherapy
    • no jewelry, inspect skin
    • put body part in sleeve and seal
    • adjust agitation and temperature levels
    • treat for 20 min.
  35. what are the contraindications to superficial heat
    • loss of sensation – numbness of skin
    • inadequate blood flow – peripheral vascular disease (smokers, diabetics)
    • acute inflammation (it will increase inflammation)
    • over malignancy (can send cancer cells out)
    • patient unresponsive or confused
  36. true or false – it is okay to use superficial heat for acute pain
    true
  37. name some precautions for superficial heat
    • edema: chronic inflammation is okay
    • pregnancy: don't go over abdomen
    • open wound: be cautious of infection
    • cardiac insufficiency
    • superficial ointments: if they open the pores they can make heat treatments worse
