application of heat and cold

1. Therapeutic 2. Comfort 3. Rehabilitation
Factors to Consider in Safe Application of Heat and Cold
1. Patient’s Condition
▪ Age
▪ Circulatory or neurologic deficiencies
▪ Level of consciousness
▪ Amount of body fats
▪ Condition of the skin in the area being treated
▪ Patient’s diagnosis
2. Adaptation of thermal receptors
3. Thermal application must be stopped before “rebound phenomenon” begins
Rebound phenomenon
▪ occurs at the time the maximum therapeutic effects of
hot or cold application is achieved and the opposite
effects begin.
▪ negates the therapeutic effect of heat and cold
application.
* 20- 30 minutes – maximum vasodilatation heat produces
* 60 F / 15 C – temperature of the skin when maximum
vasoconstriction occurs
• Continuation of heat application beyond 30 – 45 mins.
May result to tissue congestion, vasoconstriction and
client’s at risk of burn
• Continuation of cold application below 15°C
May result to vasodilatation begins w/c is protective &
prevents freezing of body tissues
• Prolonged cold application
May result to impaired circulation, cell deprivation &
subsequent tissue damage due to lack of oxygen &
nourishment
SIGNS OF TISSUE DAMAGEa. bluish & mottled skin appearanceb. numbnessc. stiffnessd. pallore. sometimes blister & pain
4. Moisture conducts heat better than air5. Length of exposure and the area to be
exposed 6. Condition of the equipment
• The length of time the body is exposed as well as
the size of the skin area being treated affects the
body to tolerate the treatment:
– Smaller area – shorter exposure = better tolerance
– Larger area of exposure = lower tolerance
• Feel hot and cold applications most while the skin
temperature is changing and after a period of time
tolerance increases.
LOCAL EFFECTS OF HEAT AND COLD
Physiologic Response to HEAT
• Vasodilation of peripheral blood vessels
• Increase blood flow (to injured body part)
• Increase supply of oxygen
• Decrease blood viscosity
• Increase tissue metabolism
• Improve circulation
Physiologic Response to COLD
• Vasoconstriction of peripheral blood vessels
• Decrease blood circulation
• Decrease capillary permeability
• Delayed re-absorption of fluid
• Increase coagulation of blood
Systemic Effects
• Heat – CO & PR, sweating, BP
• Cold - BP, shivering, goose bumps
• Heat and cold in one body part is found in
another area of the body
Hypothalamus
– Responds to signals from the thermal receptors
– Controls body temperature
– Thermoregulatory centre in the brain.
• Anterior hypothalamus – dissipate heat
• Posterior hypothalamus – conserve heat

Devices used for HEAT Application
1. DRY Heat• Hot water bags or bottles
• Electric heating pad
• Aquathermia pad
• Heat Lamp
• Heat Cradle
• Hot packs
• Gel filled hot packs
• Thermal blanket (heating)
• Diathermy
Aquathermia pad
• It is a rubber pad of
tubular construction that
can be filled with distilled
water, an electrical unit
heats the water and keeps
it at an even temperature
Aquathermia pad
• Steps in applying Aquathermia pad
(K pad)
1. Fill reservoir of unit 2/3 full
distilled water
2. set desired temperature = 40.5 C
(105 F) adults
3. cover and plug unit
4. apply to body part (continue for
30 minutes.)
Electric Heating Pad
▪ This provides constant and
even heat.
▪ It has wires that provide
heat should be covered by
rubber or plastic to ensure
safety
▪ Should never use in the
presence of moisture
because of the danger of
electric shock
Heat Lamp
• It is a gooseneck
lamp containing a
60-watt bulb, applied
18-24 inches from
the body
Heat Cradle
• A metal cradle in which
several electric sockets
are installed for 25-watt
luminous bulb, applied
18 inches away from
the patient
Hot Packs
• commercially prepared and
disposable
• instructions depending on
the manufacturer
Gel-filled Hot Packs
• Gel-filled hot
packs are available
commercially and
are reusable
• Be certain to read
manufacturer’s
instructions
Thermal Blanket
• Similar to the water-
flow heating pad
except that it is of
blanket size
Diathermy
Diathermy
• Deep heat treatment
• Electrical energy is changed to heat similar to the
principle underlying the microwave
Definition: A common form of dry heat used at
home
HOT WATER BAG
APPLICATION
Equipment
• Pitcher with hot water
• Hot water bag
• Towel
• Bath thermometer for hot water (optional)
• Dropper or a stick
HOT WATER BAG Application
1. Check the order & specify2. Identify the patient3. Assess the general condition of the patient 4. Explain the procedure5. Prepare equipment & supplies.6. Wash hands.7. Provide privacy and comfort, exposing only the
area to be treated.8. Check temperature of water using bath
thermometer or test on inner wrist. (Make sure heat will be within the acceptable range for individual). Rinse bag with water, empty, then fill to warm the rubber.
9. Fill the hot water bag half to 2/3 full.
HOT WATER BAG Application
10. Expel remaining air from bag in one of two ways: place the bag on a flat surface, permit water to come to the opening and then close the bag or hold the bag up, twist the portion to remove the air and then close the bag. Fasten up securely. Check for leaks.
***Air reduces pliability of the bag. Securing the top prevents leakage of water and discomfort for the patient.
11. Cover the bag with towel or other protector & apply to prescribed area.***Covering the device protects the skin from direct contact with rubber. Heat travels by conduction from one object to another.
12. Remove hot water bag after 15- 20 minutes (or as ordered by the physician).
HOT WATER BAG Application
13. Evaluate the following: 1) signs and symptoms of both desirable and undesirable response to treatment and 2) patient’s comfort
14. Document the treatment, including the length, time, and patient’s response.
15. Perform hand hygiene
Note:Adult and child over 2 yrs – 46 C to 52 C (115 F – 125 F)Deliberated/unconscious adult or child under 2 yrs. – 40.5 C to 46 C (105 - 115 F
2. MOIST Heat
• Warm moist compress

encrusted secretions and
dead tissue
Definition: A form of local moist heat application
done with compress cloth.

area affected.
WARM COMPRESS Application
1. Check the order & specify2. Identify the patient3. Assess the general condition of the patient 4. Explain the procedure5. Prepare equipment & supplies.6. Wash hands.7. Provide privacy & comfort.8. Prepare compress. Pour warm water into the
basin & place the towel on it. Check temperature of warm water with inner wrist.
WARM COMPRESS Application
9. Apply the heated towel. 10. After 20-30 minutes, remove warm compress. 11. Evaluate the following: 1) signs and symptoms
of both desirable and undesirable response to treatment and 2) patient’s comfort
12. Document the treatment, including the length, time, and patient’s response.
13. Perform hand hygiene.
Devices used for COLD Application
1. DRY Cold
• Ice bags / ice collar
• Cold packs / ice packs
• Gel filled cold packs
• Thermal blanket (cooling)
Ice Bags/Ice Collars
Ice Bags/Ice Collars
• commercially prepared ice bags
• these bags cannot be reused
Gel-filled Cold packs
• available
commercially and
reusable
Thermal Blanket (Cooling)
• commonly referred as
hypothermia blanket
• the blanket cools the
patient to the desired
body temperature and
maintains that level
2.MOIST Cold
• Cold compress
• Cold sponge bath
Cold Sponge Bath
• Used to lower temperature• Heat dissipates both by heat
conduction and evaporation
• Alcohol is not added
anymore due to the harmful
effect of its fumes and its
extreme drying effect
Definition: Ice bags, like their counterpart hot
water bottles or bags, are relatively easy and
inexpensive method for applying cold to the area
affected.
ICE BAG
APPLICATION
Equipment
• Ice bag or collar
• Ice chips
• Bath towel or absorbent pad
• Towel or pillow case
ICE BAGS Application
1. Check the order & specify2. Identify the patient3. Assess the general condition of
the patient4. Explain the procedure5. Prepare equipment &
supplies.6. Wash hands.7. Provide privacy & comfort8. Place towel or absorbent pad
under area to be treated.
9. Prepare ice bag or collar:a. Fill bag with water, secure cap & invert.b. Empty water & then fill bag 2/3 full with
small ice chips. c. Release excess air from bag by
squeezing its sides before securing cap.d. Wipe bag dry. e. Apply snugly over area.
10. Check condition of the skin every 5 minutes 11. After 15- 20 minutes (or as ordered by the
physician), remove cold application & gently dry off any moisture.*** Drying prevents maceration of the skin.
Prolonged application of cold can result in diminished blood flow and tissue ischemia or compensatory vasodilatation to provide warmth to area being treated.
