摘要

Abstract

Objective

This study performed a fit testing of medical respirators so as to guide medical personnel to choose suitable medical respirators based on the test results and achieve the optimized protection effect.

Methods

The study applied a 3MTM FT-30 qualitative fit testing using a test solution of denatonium benzoate. The personnel wearing the Winner Medical Respirator were tested for the fit and sensitivity (taste).

Results

A total of 649 personnel participated in the fit testing

of whom 614 (94.6%) were qualified

and 35 (5.4%) failed. Those who failed the test had smaller faces

higher nasal bridges

and lower body mass indices.

Conclusion

The fit testing of medical respirators enables medical personnel to correctly select and use medical respirators that meet protection requirements

ensuring the optimal protective effect.
