- multiple types of face mask are used for personal protection
- personal protection
- protection of patient from health care nasopharyngeal secretions
Standard Surgical Facemask (some come with a visor attached)
N95 Face Mask (‘duckbill’)
N100 Face Mask
- see here
METHOD OF INSERTION AND/OR USE
- placed over the mouth and nose
Surgical Face Mask
- designed to catch bacteria shed in liquid droplets and aerosol form from the wearer’s mouth and nose
- can protect wearer from being splashed in the mouth from body fluids
- also serves as a reminder not to touch mouth or nose
- they do not prevent inhalation of bacteria or viruses
- Used for respiratory droplet infection spread (eg SARS, influenza, Tb) for general presence in room (not procedures)
- used for reverse barrier nursing in severely immunocompromised patients
- certified to filter 95% of particles of a particular test size
- The N refers to the ability to resist oil (N stands for Non-oil resistant). R means resistant to oil and P means oil proof
- filters out the droplets that carry viruses (the viruses themselves would be small enough to pass through the filter)
- should not be put back on if removed
- should be replaced every 6 hours (WHO recommendation)
- more expensive
- highest filtering of respiratory particles/diseases
- CDC recommends masks better than N95 for procedures likely to produce droplets (e.g. airway suctioning, intubation) if airborne precautions are needed
