PrevMed2- PPE

  1. Describe the microflora of human hands.
    • resident microflora- supposed to be there, maintain normal environment of our skin
    • transient microflora- more likely to be pathogenic, easier to remove
  2. What is the purpose of hand hygiene? (2)
    • reduce transient flora
    • reduce transfer of transient flora
  3. A 20% increase in adherence to good hand hygiene showed an effect of...
    40% decrease in hospital-associated infections
  4. What are the key components to hand hygiene success? (3)
    • agent
    • timing-frequency
    • techinque
  5. How do alcohol-based hand sanitizers work?
    denature proteins, kill (not remove) microbes
  6. How does soap and water work?
    • emulsifying (break up oils) and mechanically removing microbes
    • strips moisture/oil from the skin
  7. If there's concern for non-enveloped viruses, clostridial spores, crypto, etc (more resistant organisms), what method of hand hygiene should you use?
    • soap and water!
    • hand sanitizer is not generally effective against these organisms
  8. When should you use soap and water? (4)
    • visibly soiled
    • Clostridium
    • Crypto
    • Non-enveloped viruses
  9. What are 5 instances you should wash your hands?
    • immediately before and after contact with a patient or environment
    • after contact with a patient's body fluids
    • after removing gloves
    • before eating
    • after using the restroom
  10. What is the proper hand washing technique? (5)
    • special attention to fingertips, between fingers, backs of hands, and base of thumbs
    • clean a MINIMUM or 15s
    • keep nails short
    • minimize jewelry
    • creams and lotions are ok afterwards
  11. What are the purposes of PPE? (2)
    • reduces contamination of clothing, skin, environment
    • protect from colonization/ infection
  12. What are the principals of wearing gloves?
    • wear gloves when cleaning or when you'll be in contact with body fluids, blood, secretions, mucous membranes, wounds, infectious patients
    • do NOT touch surfaces that may be touched by people with non-gloved hands
  13. When is a surgical mask/ goggles imperative? (6)
    • dental procedures
    • surgery
    • wound lavage
    • abscesses
    • obstetrics
    • necropsy
    • [splashes/ sprays into eyes/ MMs likely]
  14. When is respiratory protection important (N95 respirators)?
    • masks to filter non-oily particular aerosols
    • few indications in clinical practice- tularemia, TB
  15. You're most likely to contaminate yourself when...
    removing PPE.
  16. 2 major concerns for PPE in an outbreak.
    exposure potential: respiratory protection, dermal protection
  17. What are the levels of PPE?
    • A: greatest level of skin, respiratory, and eye protection
    • B: highest level of respiratory protection; lesser level of skin protection
    • C: concentrations an types of airborne substances known; criteria for using air purifying respirators met
    • D: minimal protection; "nuisance" contamination only (coveralls, boots, exam gloves, safety glasses)
