The National Institute for Occupational Safety and Health also certifies respirators according to their filter efficiencies, in order to rank the protective performances of the various N95 respirators [5, 6].
"Airborne-transmissible diseases, such as tuberculosis, require using an N95 respirator instead of a procedure mask.
Joe Palomo, engineering manager in Global Engineering and Tech Support at Cardinal Health, added: "The filtration tests for surgical masks are not as stringent as surgical N95 respirators. Surgical masks, including high-filtration surgical laser masks, do not seal to the face and may allow dangerous contaminants to enter the healthcare worker's breathing area."
N95 respirator and patient isolation in an airborne infection isolation room) were instituted.
Study authors cautioned that their study was "observational," but "nonetheless our findings show that surgical masks and N95 respirators do not appear to differ in efficacy." CDC and other health-related organizations, including the Institute of Medicine, have recommended that health care workers who come in contact with suspected or confirmed H1N1 cases use N95 respirators, the most frequently used respirator in health care settings.
The new analysis of results from an Australian and Chinese study that compared the efficacy of N95 respirators and surgical masks in blocking transmission of influenza and other viruses to health care workers showed that the relatively expensive and uncomfortable respirators were not significantly better than surgical masks for preventing transmission, Holly Seale, Ph.D., reported at the annual meeting of the Infectious Diseases Society of America (IDSA).
N95 respirator face masks are designed to prevent the entry of airborne particles and these are the appropriate masks to be worn by the treating medical staff, while the surgical face mask is designed to prevent the airborne spread of disease and is the appropriate mask to be worn by a person suspected of suffering from the disease.
The CDC's recommendations for health care personnel include staying home when ill; washing hands frequently; and using protective gear including surgical masks, N95 respirators, gloves, and surgical gowns, as well as eye protection.
For protection against anthrax exposure, adequate protection is provided by using the N95 respirator face mask, latex gloves, and a smock or coveralls.
The Centers for Disease Control and Prevention (CDC) recommends an N95 Respirator for respiratory-exposure protection against Mycobacterium tuberculosis.
Offenders were compensated using the standard IDOC pay schedule and underwent medical clearance, N95 respirator fit testing, and job-specific training that included information about the zoonotic potential of avian influenza viruses.
Also, some HCPs wore only a surgical mask as PPE during the initial bronchoscopies and/or were unsure if they had always maintained a properly fitted N95 respirator during subsequent bronchoscopies.
