Flashcards do conjunto (26)
- 1The ________ is the temperature regulating center in the body.Hypothalamus
- 2______ ______ in the skin, muscles, & joints send impulses to the hypothalamus.Sensory Receptors
- 3What are two changes in circulation?Vasodilation & Vasoconstriction
- 4The extent of temperature change results from several of the following factors:1: Temp difference between agent & target tissue. 2: Time of exposure to agent. 3: Thermal conductivity of the target tissue. 4: Intensity of the agent.
- 5______ ______ acts as insulation to underlying tissues, thus limiting the degree of temperature change in deeper tissues.Adipose Tissue
- 6Heat loss or gain through direct contact between materials with diff. temperatures.Conduction (Hot & Cold Pack)
- 7Transference of heat to a body by the movement of air, matter, or liquid around or past the body.Convection (Fluidotherapy, Heat Pump)
- 8Radiant energy transfers heat through air from a warmer source to a cooler source.Radiation (Infrared)
- 9Temp change that results from energy transformed from one form to another.Conversion (US)
- 10Transformation from a liquid state to a gas state.Evaporation (Sweat)
- 112 types of therapeutic heat. Name them and describe them.Superficial: 2 cm or less, skin & subcutaneous.
Deep: 3-5 cm, muscles & joint capsules - 12Physiologic Effects of Heat vary according to:Intensity of agent, duration of application, area being treated
- 13Physiologic Effects of Heat result in:Increase blood flow (vasodilation)
Increased metabolic rate
Increased oxygen release (wound healing) - 14Pain ReductionGate Control Theory
Counterirritation
Elevates Pain Threshold - 15Reduction of muscle guarding or spasmDecrease muscle tonic activity
- 16Greater increase in blood flow with ____ & ____.Heat & Exercise
- 17Heat should be applied ___-___ minutes for maximal benefit.15-30
- 18How long should you leave a hydrocollator pack on?20 minutes
- 19What should the water temp be for hydrocollator packs and how many layers are required for them?Water Temp: 160-175 F
6-10 layers - 20How long should paraffin be left on? Temp? Dips?20 minutes, 116-130 F, 8-10 dips
- 21Name a few contraindications for heat.*Acute Inflammation*Existing Fever*Malignancies*Acute Hemorrage*PVD*Radiation Therapy*Undressed or Infected Wounds*Lack of Sensation*Metal Implants*Pacemaker
- 22Name precautions for heatDecreased Sensation*During menses*During pregnancy*Open Wounds*Pacemaker*Impaired Cognitive Ability
- 23Physiologic Effects of ColdVasoconstriction, Shivering, "Hunting Response", Temp Change 1-4 cm, Decrease elasticity & viscosity of tissue, decrease metabolic rate & slows production of metabolites
- 24What are the stages of cold?Cold, Burning, Stinging, Aching, Numbness
- 25Contraindications of ColdCold Urticaria*Cryoglobulinemia*Raynauds*Circulatory Impairments*PVD*Wound Healing/Open Wound/Infection*Hypersensitivity to cold*Lack of Sensation*Paroxysmal Cold Hemoglobinuria
- 26Precautions to ColdDecreased Sensation, Impaired cognitive ability
