2.  Aseptic practices: used to keep an area free of disease producing microorganisms  Medical Asepsis: “clean technique”, purpose is to keep a clean environment so disease won’t spread. EX: hand washing, gloves  Surgical Asepsis: “sterile technique” a sterile environment in which there are no microorganisms or spores.

3.  Airborne Precautions:  disease that is spread by droplets in the air.  Must wear filter mask, and have negative pressure in the room  Droplet Precautions:  Spread when someone sneezes or coughs  Should wear a mask  Contact Precautions  Could get transmission by contact or non contact  Have wound covered with sterile dressing at all times

4.  Infection only happens if the pathogens alter the normal function of tissue.  They take up space and nutrients which allows them to get bigger and stronger.

5.  6 factors must be present for an infection to occur.  If chain is never broken…NO infection should occur!  Washing your hands will prevent the spread of disease = infection = no infection

6.  Mostly harmless microorganisms  When they multiply they become harmful  They multiply in a reservoir. … Infectious Agent

7.  Reservoirs = humans, insects, food water, bed linen or books  Pathogens stay in the reservoir until they can escape Reservoir

8.  Escape routes  Respiratory tract  Skin  Blood  GI tract  Mucous membranes Portal of Exit

9.  The way in which a pathogen goes from place to place  Can be spread by direct contact or airborne droplet  Proper hand washing is the best practice to prevent transmission Mode of Transmission

10.  Pathogens need a portal of entry for transmission.  Routes of entry:  Respiratory tract  Mucous membranes  GI tract  Cut on skin Portal of Entry

11.  One that is capable of becoming infected  Microorganisms must be present in large quantity  Host must be susceptible  If you are immune you are not susceptible Susceptible Host

12. Inf. Agent Reservoir Portal of exit Mode of Transmission Portal of entry Susceptible Host
