SALAME ORTIZ, Verónica Alejandra  and  BAUTISTA JIMENEZ, Karla Valeria. Methods for decontamination and reuse of the n95 respirator during the sars-cov-2 pandemic. Conrado [online]. 2021, vol.17, n.83, pp. 311-317.  Epub Dec 10, 2021. ISSN 1990-8644.

The SARS-CoV-2 pandemic threatens public health around the world, and healthcare professionals are at increased risk due to their close contact with patients. NIOSH certified N95 masks, can filter 95% of particles in the air and are therefore currently recommended by the Center for Disease Control for use by health professionals in the face of the pandemic. The shortage of protective equipment, including N95 respirators, has generated the need for rationing this resource. The objective of this systematic review is to identify effective methods for the decontamination of the N95 respirator, which maintain its filtration and fit properties for reuse. A earch of digital resources was carried out in databases: Pubmed, medRxiv, IJOS, Scielo, Elsevier; systemic analysis, meta-analysis, clinical trials were accepted. Based on the results obtained, it can be determined that vaporized hydrogen peroxide and ultraviolet germicidal irradiation are the most recommended methods, due to their germicidal efficacy, and they also maintain the filtration and adjustment capacity of the respirator. More research is needed to generate protocols that allow the safe reuse of this resource.
