What are the 4 factors required for infection to spread? |
|
Definition
* The number of organsim.
*The virulence of the organism its strength or ability to cause disease.
*The person's immune systems.
*Length and intimacy of the contact, how long on the body and how close.

Definition
*Intact skin and mucous membrane.
*Normal PH lvl of the gastric secretion of the GI tract.
*WBC

Term
Stage 1of the Inflammatory Process
Description |
|
Definition
* Initial injury precipitates release of the chemical.
*Release of chemicals
*Histamine bradykin,serotinin,prostaglandin, and lymphokines

Stage 1of the Inflammatory Process
Result
|
|
Definition
Activation of the inflammtory response. |

|
Term
Stage 2 of the Inflammatory Process
(Description)
|
|
Definition
Increased blood flow to the inflamed area (erythema) |
|
|
Term
Stage 2 of the Inflammatory Process
(Result)
|
|
Definition
Redden and warm around the area |
|
|
Term
Stage 3 of the Inflammtory Process
(description)
|
|
Definition
Increased capillary permeability with leakage of large quantities of plasma out of the capillaries into the damaged tissue.
Tissue spaces and lymphatics blocked by fibrinogen
|
|
|
Term
Stage 3 of the Inflammtory Process
(Result)
|
|
Definition
| Walling of the infection bumped up |
|
|
Term
Stage 4 of the inflammatory process
(description)
|
|
Definition
damaged tissues infiltrated by leukocytes, which engulf the bacteria and necrotic tissue.
After several days, these leukocytes eventually die and form a cavity of necrotic tissue amd dead leukocytes.

|
Definition
| Destroyed tissue cells are repalced with identical or similar strurctural and fucntioning cells and/or fibronous tissue |

Term
Systemic responses to Inflammation are |
|
Definition
*Fever
*invreased WBC's
*malaise
*lethargy
|
|
|
Term
Cardinal Sysmptoms of Local Inflammation are |
|
Definition
* redness
*warmth
*swelling
*pain
*decreased function just in the injured area
|
|
|
Term
Reason for Cold Application |
|
Definition
* Control bleeding-slows flow, increase viscosity.
*Prevent swelling-decreased capillary permeablilty.
*cools the body-sponge bath to decrease temperature
*Releives superficial pain-slows down conduction rate.
*Muscles spasm-increase muscle relaxation by contractility
|
|
|
Term
Indications for Heat Application |
|
Definition
* Inflammation-increased blood flow yielding phagocytosis. More nutrients for healing soften and exudates.
*Contraction-allows greater distention of muscles and connective tissue decreased contracture and increase joint ROM.
*Joint stiffness-decreased viscoisty of synovial fluid.
|

Term
Indications for Heat Application
(cont'd)
|
|
Definition
* rewarm body parts
*Hasten healing suppuration
*pain-promoting muscle relxation increase circulation
*Muscle spasm-relaxes muscle increases contractiltiy.

Body response to cold and heat |
|
Definition
cold heat
down blood flow up
down capillary permeability up
down metabolism up
down inflammatory response up
up blood viscoisty down

Term
What is the rebound phenomenon? |
|
Definition
Occurs at time maximum therapeutic effect of application is acheived and the opposite effect begins. |
|
|
Term
What are some legal implications? |
|
Definition
* Not protecting the skin.
*Too hot or cold.
*Not chekcing frequently
* Using treatment without order.
|
|
|
Term
First Intention of Healing |
|
Definition
* Wound made aseptically
*Wound is clean in a straight line with little loss of tissue
*all wound-edges are well approxiamted
*Usually rapid healing with minimal scarring.
example: surgical incision
|
|
|
Term
Secondary Intention of Healing |
|
Definition
* Large wound with condsiderable tissue loss
*Natural healing by formation of granulation tissue
*Helaing takes longer and results in more scarring.
example: pack wound and use dressing, heals inside and out
example: Stage IV decubitis ulcer
|
|
|
Term
Tertiary intention of healing |
|
Definition
* Time dealy before wound is sutured
*greater garnulation, greter risk of infetion greater inflammotry reaction than primary intention.
*late suturing and mroe scarring.
example: Large injurious laceration
