PPE

Emergency Department PPE
  • When to discard N95 respirators: 
    • Following use during aerosol generating procedures
    • Contaminated with blood, respiratory or nasal secretions, or other bodily fluids from patients
    • Following close contact with any patient co-infected with an infectious disease requiring contact precautions
    • If inadvertent contact is made with the inside of the respirator, discard the respirator and perform hand hygiene as described above

 

  • A key consideration for safe extended use is that the respirator must maintain its fit and function

 

  • If you plan to re-use N95 respirators:
    • Consider use of a cleanable face shield over an N95 respirator
    • Hang used respirators in a designated storage area or keep them in a clean, breathable container (labeled paper bag) between uses
    • Clean hands with soap and water or an alcohol-based hand sanitizer before and after touching or adjusting the respirator
    • Avoid touching the inside of the respirator. If inadvertent contact is made with the inside of the respirator, discard the respirator and perform hand hygiene as described above
    • Use a pair of clean (non-sterile) gloves when donning a used N95 respirator and performing a user seal check. Discard gloves after the N95 respirator is donned and any adjustments are made

  • When to discard isolation gowns:
    • The same gown can be worn by the same healthcare professional when interacting with more than one patient known to be infected with the same infectious disease when these patients are housed in the same location (i.e., COVID-19 patients residing in an isolation cohort)
    • If the gown becomes visibly soiled, it must be removed and discarded as per usual practices

  • When to discard of eye protection: 
    • If it becomes visibly soiled or difficult to see through
    • If damaged
    • If visibility is obscured and reprocessing does not restore visibility
  • How to reprocess eye protection: 
    • While wearing gloves, carefully wipe the inside, followed by the outside of the face shield or goggles using a clean cloth saturated with neutral detergent solution or cleaner wipe.
    • Carefully wipe the outside of the face shield or goggles using a wipe or clean cloth saturated with EPA-registered hospital disinfectant solution.
    • Wipe the outside of face shield or goggles with clean water or alcohol to remove residue.
    • Fully dry (air dry or use clean absorbent towels).
    • Remove gloves and perform hand hygiene.

CDC Burn Rate Calculator

  • Designed to help healthcare and non-healthcare facilities optimize use of PPE.

Use Guide:

  • Enter the number of full boxes of each type of PPE in stock (gowns, gloves, surgical masks etc.).
  • Enter total number of patients at your facility.
  • The calculated “burn rate" will estimate how long the remaining supply of PPE will last.

Mask Rotation:

This method involves acquiring a set number of N95 masks and rotating their use each day, allowing them to dry for long enough that the virus is no longer viable. According to a Lancet study Covid-19 can live on surgical masks up to 7 days, thus ideally having 7 masks you can rotate may help prolong the life of the masks and decrease contamination.

Your mask can be stored in a labeled paper bag or tupperware container. 

Mask Decontamination: 

  • Heat: not currently recommended
  • UV Treatment: Home UV light use is not recommended however this method of decontamination has been implemented by some hospital systems in the United States such as UMass and Nebraska Med.
  • Hydrogen peroxide vapor (HPV): Approved by the FDA as a method for N95 decontamination for healthcare personnel during the COVID-19 pandemic. This method of decontamination is actively being implemented by hospital systems across the United States through Battelle.
