Abstract

Hospital environments have a wide variety of viruses in circulation by the number of people who work and are served in these places. The purpose of this study is to verify which type of respirator is most suitable for protecting these professionals. The experimental study will use two compressors, three flow meters, a mannequin, a rotary feeder, the PFF-2 and N-95 respirators, a motorized air purifier and a chamber to simulate the contaminated environment. Negative pressure masks are expected to present sealing failures, demonstrating exposure of the professionals who use them, whereas for positive pressure masks, sealing failure is expected but in the direction of air exit, not exposing users to the biological agents described In this job.
