NCT05079308

Brief Summary

A significant number of professionals subjected to high-risk situations have been infected by Covid-19, due to the lack of adequate respiratory protection equipment or poor marginal sealing adjustments. Then, the objective of this study is to determine if there are statistically significant differences in the level of respiratory protection of type IIR surgical face masks and filtering face masks, used with and without a peripheral sealing device, against the contagion of Covid-19 or other harmful biological agents. The proposed device is a thermoplastic resin ring composed of a reusable and biodegradable polylactic acid designed to be used in a healthcare environment. The individuals of the study will be submitted to qualitative fit tests, that meet current Ocupational Security and Health Administration (OSHA) standard. The mentioned qualitative fit test uses a sodium saccharin solution to evaluate the respiratory protection equipment in professionals in hospitals, emergency centers, and early childhood education centers.

Outcome Measures

Primary Outcomes (1)

  • Qualitative analysis of the respiratory protective equipment in protecting against the simulated aerosol: intergroup comparison

    A qualitative analysis will be performed in order to evaluate whether the respiratory protective equipment is effective in protecting the individuals from a simulated aerosol environment. The individuals will be submitted to 7 different breathing exercises inside of a hood with their open mouth. A nebulizer filled with sacharin solution will be used to simulate an aerosol environment. If the individual do not sense the taste during the whole breathing exercises (total of 7 minutes) the respiratory protective equipment (RPE) used by this individual will be scored as "PASSED". If the individial sense the sweet taste during the 7 minutes, the RPE will be scored as "FAILED". The answer of the individuals using masks with the Peripheral Sealing Device and the controls (individual using masks without the peripheral sealing device) within each group will be compared. There is only one outcome measure: evaluate if the individuals are able to sense the aeresol or not.

    up to 5 months

Secondary Outcomes (1)

  • Qualitative analysis of the respiratory protective equipment in protecting against the simulated aerosol: intragroup comparison

    up to 5 months
