Current practice is to use N95 masks during transfer; however, oxygen provision is a common clinical challenge when wearing N95 masks. Third, it can also be used as PPE. Different protection effects can be achieved by installing different filters on this mask, such as high-efficiency particulate...

Healthcare personnel who work in outpatient settings will be cluster-randomized to wear N95 respirators or medical masks for protection against infections during respiratory virus season. Outcome measures will include laboratory-confirmed viral respiratory infections, acute respiratory illness, and influenza-...
This is due to the reporting of re- sults in the form of intermediate outcomes (e.g. case pre- vented) and the analysis of combinations of masks/ respirators with other protection measures in evaluations [12, 21, 22]. There was also limited inclusion of clinical data to inform the ...
These masks can be used both for source control (ie, reducing spread from an infected person) and for protection of the wearer (ie, preventing spread to an unaffected person). The protective efficacy of N95 masks depends on their ability to filter incoming air from aerosolized droplet nuclei....
Why do we not have more RCTs on masks to prevent the spread of SARS-CoV-2? In a pandemic caused by a lethal respiratory virus, it is difficult to find a setting in which it is ethical and feasible to randomize people to masking vs no masking. The time needed for RCTs to be funded...
Masks for Prevention of Respiratory Virus Infections, Including SARS-CoV-2, in Health Care and Community Settings : A Living Rapid Review. Recommendations on masks for preventing coronavirus disease 2019 (COVID-19) vary. To examine the effectiveness of N95, surgical, and cloth masks in community...
Researchers may finally have an answer in the long-running controversy over whether the common surgical mask is as effective as more expensive respirator-type masks in protecting health care workers from flu and other respiratory viruses. A study published today inJAMAcompared the ubiquitous surgical ...
