Lesson 10: Patient Care (4) Flashcards
Hot and Cold Applications
Both warm and cold applications can be ordered in two ways:
moist and dry application
Warm and cold applications have several purposes (3)
- To decrease discomfort and reduce pain
- To reduce the swelling of damaged tissues
- To promote the healing of damaged areas and tissue repair
Blood vessels
These provide nutrients and oxygen to the tissues and then remove waste products and carbon dioxide from the tissues.
- The vessels infiltrated every part of the tissues.
- Veins carry blood back to the heart
- Arteries carry blood away from the heart
- Blood vessels begin with the largest artery attached to the heart, the aorta, and become progressively smaller and smaller as they move away from the heart
- As they get smaller and smaller, they are referred to by different names: arteries, arterioles, and capillaries
Capillaries
These are tiny vessels that reside in almost every part of the tissues of the body.
- These then connect to the veins that move the blood back to the heart
Veins
Veins get progressively larger and are reffered to as venules, veins, and finally the largest veins the superior and inferior vena cava, which connect to the heart once again.
Circulatory system
The body’s network pushes the movement of blood through vessels, which is called circulation.
How do warm and cold applications use the blood vessels to help reduce pain and swelling and increase tissue repair?
- Blood vessels constrcit and dialtate in response to temperature changes.
- Heat causes the blood vessels to dilate and cold causes them to constrict.
- Because of this sensitivity to temperature, physicians can use warm and cold applications to control what happens in the tissues of specific body area
- Remeber that normal body temperature is about 98.6F or 37.0C
Effect of heat
Heat is applied to a part of the body to speed up the healing process
- It does this by dilatingthe blood vessels in the area, causing more blood to circulate to the damaged body tissues where the heat is applied
- Increased circulation means an increased amount of blood to the tissues; increasing the amount of blood in turn brings increased nutrients and oxygen the blood carries
- Heat may be applied to an area of the body to ease pain that is caused by inflammation and congestion
- When the vessels become dilated, an increased supply of blood can carry away the fluids causing the inflammation and pain
Effect of cold
- Swelling of body tissues causes tissue damage and delays healing.
- Cold is applied to body areas to constrict or decrease the amount of blood flowing to the area
- Cold applications on the area also reduce pain
When the damaged area becomes colder, less blood and fluid seep out of the cappillaries into the tissues - Cold also slows down the rate at which blood escapes from a cut or a hole in a vessel.
- In cases of hyperthermia, cold may also be applied to the individual’s entire body to reduce its temperature.
- A special blanket, called a hypothermia blanket, is typically used.
Examples of moist applications:
compresses and soaks
Compress
A moist application in which a cloth is dipped into water, the excess water is wrung out, and the cloth is applied to the skin.
- This is a localized application, meaning it is applied to one specific part of the body
Soak
This can either be a localized or a generalized application
- Generalized means that it affects or invleves the entire body.
Moist applications
This is an application in which water touches the skin, and the surface of the application is moist.
- Examples are: cool wet packs, hot and cold compresses, sitz bath, warm or cold soak, and tub bath
Dry aplications
This is an application in which no water touches the skin, and the surface of the application is dry.
- Examples: Aquamatic K-pad, commercial unit warm or cold packs, hypothermia blankets, and heating pads
Procedures for Applying Moist Heat
Step 1: Assemble the Equipment
Step 2: Ready the Individual
Step 3: Complete the Procedure
Step 4: Clean the Area and Equipment
Step 5: Follow Up
Applying moist heat: Step 1
- Assemble the equipment
- disposable bed protector
- basin
- pitcher of water that is 98F pr 37C
- washcloth, towel, or gauze pads
- large sheet of plastic
- bath towel
- bath blanket
- disposable gloves - Wash your hands and apply gloves if there is risk of open wounds
Applying moist heat: Step 2
- Identify the individual, if you are in a facility
- Tell the person that you are going to apply a warm compress and where it will be applied.
- Ensure the person’s privacy and comfort.
- Raise the bed toa. comfortable working position, if you are using a hospital-type bed.
- Help the person to a comfortable and expose the body area for application of a warm compress
- Place a disposable bed protector under the body area that is to be given the warm compress.
- Fill a pitcher with warm water and pour it into a basin.
Applying moist heat: Step 3
- Dip the compress into the water and wring it out thoroughly.
- Apply the compress gently to the proper area.
- Cover the wet compress by wrapping the entire area with a large towel or body wrap.
- Cover the are, compress, and towl with a waterproof pad.
- Cover the person with a blanket if she becomes cold.
- Change the compress and remoisten it as necessary to keep it warm. Allow the individual to apply the compress herself if she is able and your supervising nurse allows.
- Check the skin under the application every 5 minutes. If the skin appears red, remove the compress. Cover the area with a towel and report your findings to a nurse or physician. Document your findings as appropriate.
- When the treatment is completed, remove the compress and pat the area dry with a towel.
Applying moist heat: Step 4
- Clean the equipment and store it.
- Discard the disposable equipment and gloves.
- Wash your hands.
Applying moist heat: Step 5
- Make the person comfortable and return the bed to its normal position. Raise the side rails if necessary and using a hospital bed.
- Report to your supervisor:
- The time the warm compress was started
- How long the compress was in place
- The area of application
- How the individual tolerated the procedure
- Any unusual or abnormal observations
Applying moist heat: Charting example
3/17/12 1000: Warm compress applied on Mrs. Jones’s left forearm for 20 minutes as ordered. Mrs. Jones reported that the compress reduced her pain. -L.Hill, CNA

- Place the person’s arm, hand, leg, or foot into the basin of water gradually.
- Check the temperature of the water every 5 minutes.
- When it needs to be changed to maintain the warm temperature, take the person;s arm, hand, leg, or foot out of the basin and wrap it with a bath blanket or towel to keep it warm.
- Refill the basin with warm water and place the area back into the basin.
- Repeat this for the prescribed time for the soak. - Check the skin every 5 minutes.
