Handwashing

The most effective way to prevent infection

Pathogen

Microorganisms that can cause infection or disease

Fomite

Contaminated non-living objects

Disinfection

A method to eliminate MOST pathogens from equipment

Sterilization

A method to eliminate ALL microorganisms from objects

Antiseptic

A liquid to ‘clean’ the skin

Cross Contamination

When microorganisms pass from one person or inanimate object to another

Standard Precaution

Standard infection control practices with the assumption that everyone could be infectious

Transmission based precaution

Standard precautions used when there is a known infectious illness

Working Height

A levelled height at which the patient is at in order for the healthcare worker to work at to prevent muscular/back strain

Medical Asepsis

Removing most pathogens, cleaning techniques, disinfections

Medical Asepsis Examples

Washing Hands, disinfecting surfaces, wearing PPE

Surgical Asepsis

Removing ALL pathogens, sterilization

Surgical Asepsis Examples

Creating a sterile field where everything inside is free of pathogens , Using an autoclave, Using sterile equipment (gloves, needles, etc)

• Droplets

  • Bigger droplets fallen on surfaces

• Contact

• Chemical hazards

• Disaster planning

• Contaminated needles

• Through air

• Contact with patients

Types of blood-borne pathogens

HIV, Hepatitis B, Hepatitis C

How are blood-borne pathogens prevented?

• Needles put in sharps containers

• Taking time

What is the best way to avoid a sharps injury?

Slow down, act in calm manners

Supine position

Used for general examination or physical assessment

Prone Position

to help relieve pain

Lateral Position

To help relieve pain/pressure on the coccyx

Sims Position

Used for rectal examination, treatments, enemas, for women is can be used for vaginal wall prolapse

Semi-Fowlers Position

To help patient with breathing problems

High-Fowlers Position

To help aid digestion and used if patients need assistance in breathing

Tredelenburg position

Used in situation like hypotension, or medical emergencies. Lets blood flow back into the important organs like the head and heart
