Principle and Practice of Asepsis Flashcards
Define Asepsis
The freedom from diesease-causing microorganism
Medical Asepsis
To confine a specific microorganism to a specific area
Objects refer to clean / dirty
Surgical Asepsis
Keep an area or object free of all microorganism
Use for all procedures involving the sterile area of body
Purpose of Asepsis
-To provide safety & comfort to patients
-To increase the effectiveness of treatment given to patients
-To decrease the possibility of transferring microorganism from one and another
Pathogen
A microorganism that cause diesease
Pathogenicity
An ability of a microorganism to produce diesease
Virulence
The frequency a pathogen producing dieseases
The ability of an organism to overcome the host defense and cause damage
Sepsis
The state of infection
Infection causing infections
-Bacteria
-Viruses
-Fungi
-Parasites
Bacteria
-The most common microorganism that caused infections
-Single cell microorganism
E.colli
Viruses
-Smallest microorgansim known to cause infection disease
Herpes simplex virus -cold sore
Rhinovirus-cold
Fungus
Yeast and molds
Candida albicans-normal flora in the human vagina
Parasite
Live on other living organism
Malaria- protozoa
Helminths- worms
Method of transmission of microorganism
-Direct
-Airborne
-Indirect-Vehicle borne,Vector borne
Direct transmission
Immediate & direct transfer of microorganism from person to another
Touching, kissing, snezzing, coughing
Indirect transmission
Vehicle borne transmission
Any substances as a ‘vehicle’ to transport & introduce microorganism into suspectible host
Toys, surgical instruments, food, water
Indirect transmission
Vector borne transmission
An animal/flying/crawing insect as an intermediate from one to another
Mosquitoes-inject blood
Flies-depositing feces
Airborne transmission
Involve droplets and dust
Types of infections
-Acute infection
-Chronic infection
-Local infection
-Systemic infection
Acute infection
Infection that appears suddenly & last a short time
Chronic infection
occurs slowly, over a very long period
Local infection
The microorganism remain the specific part of the body
Cut wound
Systemic Infection
The microorganism speard & damage different part of body
