Process of Infection

Types of Epidemiology

-Endemic: manageable rate in a specific area

-Epidemic: sudden rapid spike in a region

-Pandemic: epidemic that spreads all around

Modes of disease transort

1)DC

2)DS

3)A

4)ST and what is the spreader

5)H and what is the spreader

1)Direct Contact

2)Droplet Spread

3)Airborne

4)Strike Through; water

5)Hematogenous; blood

Etiology:

Resident Flora:

Transient Flora:

1) Study of the cause of disease

2) Permanently inhabit body and found in specific tissues

3)Don’t normally reside in body tissue, can be removed

Predisposing Factors to Wound Infection

1)Preparation for

2)Specific surgical

3)Causative

1)Surgery

2)patient

3)Microorganisms

The closer the surgery is to the heart the less likely

it is to become infected

Preparation to Surgery

-When do you shave a patient

-Where do you shave it, what do you use to contain it and how do you deal with excess

-Prepare Skin with

1) 6 hours before surgery

2)Outside the OR; heavy lather, tape

3) Antiseptic

What is Virulence

When to classify as infection

1) Strength of microorganism

2) when the microorganism number exceeds patient resistance

What must nonsterile members wear to cover arms

What are sources of containiation

1)S

2)RT

3)E

4)CA

5)GT

6)H

1)Warmup jackets

2)

-Skin

-Respiratory Tract

-Equipment

-Circulating Air

-Gastrointestinal tract

-hair

Antiseptic

chemical agent used on skin to inhibit growth of microorganisms

Asepsis

absence/elimination of pathogenic microorganisms

Fomite

inanimate source in disease transmission

Pathogen

disease causing microorganism

Surgical Sight Infection SSI

Post operative infections of surgical wound

Vector

living intermediate character of microorganisms from one host to another

Wicking

absorption of liquid by capillary action
