Infection control and healthcare systems
Microorganisms exist and maintain bodily functions
- Pathogens are microorganisms that cause diseases- Non pathogens are microorganisms that are essential to our body and don’t cause disease
Viruses require a living cell to reproduce and canNOT replicate on their own
Some viruses that infect animals have changed to infect humans.
Microorganisms do NOT thrive i cold environments but prefer warmer, darker and moist places.
Antibiotics are ONLY effective against bacteria.
Standard precautions are used with in contact with bodily fluids like
- Blood- Mucus
- Sputum
- Saliva
-Urine
- FecesTreat patients as if THEY ARE SICK and are CARRIERS of infection
NEVER recap used needles. Put them in the Sharps container
Always use gloves in procedures that involve bodily fluids
Never reuse gloves even if you think they haven’t been contaminated
Wear masks in all procedures that involve airborne or droplets
Masks should be changed frequently(Max of 30 minutes)
ALWAYS change masks if they become wet.
Use resuscitation devices instead of direct contact to reduce infection from mouth to mouth
OSHA only requires vaccinations for Hepatitis B
OSHA is not a part of the needlestick safety and prevention act
Minor injuies should be reported immediately
Linens soiled with body fluids should be treated as biohazardus and not mixed with regular laundry.
CDC(Centers for Disease Control and prevention)
the CDC is responsible for establishing standard precautions to prevent the spread of infections
Healthcare workers should follow standard precautions at all times, without exception
Under standard precautions, body fluids such as blood, urine, and saliva are infectious
Isolation methods depend on the cause of the patients disease, how it spreads and resistance to antibiotics
Certain patients will require protective or reverse isolation because of chemo or weakened immune systems
Contact precautionsNot all precautions require a mask
Gowns and gloves are necessary for direct contact precautions
DROPLET PRECAUTIONSprecautions that don’t require air to be filtered or vented outdoors
Unlike contact, these require masks
AIRBORNE
airborne precautions necessitate the use of high-efficiency masks like n-95 or hepa filters
Specific measures like airborne precautions are required for diseases such as measles, chicken pox, whooping cough, anthrax or tuberculosis.
Airborne precautions require air to be filtered or vented outdoors
UNDERSTANDING EPIDEMICS
an epidemic is a localized area while a pandemic is on a much larger scale.
OSHA STANDARDS
Employers must follow protocols and provide hepsatitis b vaccines to employees free of charge or might encounter exposure.
HAND HYGIENE
Healthcare workers st wash their hands in various situations, including
—Before and after patient contact
- when hands beome containated
before and after removing gloves
-etc.
