WHAT IS ASEPSIS?
WHAT IS EQUIPMENT DISINFECTION?
WHAT IS EQUIPMENT STERILIZATION?
means freedom from infection
use of a chemical procedure that eliminates virtually all
recognized pathogenic microorganisms but not all microbial forms
procedure used to prevent contamination by microbes and endospores before, during, and after surgery using sterile technique
WHAT IS MEDICAL ASEPTIC TECHNIQUE?
WHAT IS STERILE TECHNIQUE?
WHAT DOES IT INVOLVE (EXAMPLES?)
reduction in the numbers of infectious agents, which decreases the probability of infection
certain procedures to make sure no microorganisms contaminate a sterile field
- gowning, gloving, masking, assisting with sterile trays, preparing sterile syringes, etc.
What is the first line of defense in preventing the spread of disease?
WHAT IS STERILIZATION?
CAN YOU LEAVE A STERILE AREA UNATTENDED?
Medical aseptic technique
absolute killing of all life forms
NO, ONCE LEFT OR UNSURE - DISCARD / ASSUME CONTAMINATED
IN IV INJECTION, CLEANING THE SKIN IS EXAMPLE OF ______ & KEEPING NEEDLE & CONTRAST STERILE IS EXAMPLE OF ______-
STERILE TECHNIQUE VS MEDICAL ASEPSIS
EXAMPLES:
MEDICAL ASEPSIS / STERILE TECHNIQUE
Sterile technique is used for invasive procedures, such as surgery and inserting catheters,
medical asepsis is used for noninvasive procedures, such as measuring blood pressure and suctioning the oral cavity
WHAT IS CDC STANDARD PRECAUTIONS FOR?
IS EVERY PATIENT INFECTED? IS ALL BODILY FLUID?
EXAMPLES OF CDC ENGINEERING CONTROLS:
-precautions to prevent the transmission of disease by blood or body fluids
-an aggressive, standardized approach to infection control
EVERYTHING/ONE ASSUMED TO BE CONTAMINATED WITH HIV, HBV OR OTHER BLOOD-BORNE PATHOGEN
sharps containers, mouthpieces, ventilation bags
EXAMPLES OF CDC PPE:
EXAMPLES OF CSC WORK PRACTICE CONTROLS:
WHEN STERILE GLOVE/GOWN EXPLAIN WHAT PART IS STERILE / HOW TO PASS SOMEONE:
(gloves, masks, gowns, face shields)
(handwashing, do not recap needles)
WAIST UP / FRONT SIDE ONLY
- PASS BACK TO BACK

WHEN SHOULD YOU WASH YOUR HANDS?
WHAT IS PPE?
HAND WASHING
hands must be washed before and after every procedure regardless of whether gloves were worn
Personal Protective Equipment (PPE) refers to wearable equipment that is intended to protect a Health Care Provider (HCP) from exposure to infectious agents

Vancomycin Resistant Enterococcus (VRE) - CONTACT
wear surgical mask if within 3 feet of patient
the patient should be placed in a private room
patient wears surgical mask when transported to Radiology
drops expelled while coughing, sneezing, or talking
infected by contact with mouth, nasal mucosa, or conjunctiva
