Can homemade fit testing solutions be as effective as commercial products?

摘要

Fit testing is used to determine whether a N95 mask will provide respiratory protection for the wearer by preventing inhalation of airborne transmitted microorganisms. National guidelines recommend that healthcare workers (HCW) who use N95 masks require fit testing. Quantitative fit testing requires the purchasing and use of fit testing solutions and associated equipment. In high volume, these solutions are expensive and may not be readily available, as was seen in the 2009 H1N1 influenza pandemic. The aim of this study was to determine how a homemade solution compared against a commercially available product and a placebo.
