Materiales y m\u00e9todos: Se ha determinado una relaci\u00f3n lineal directa entre el logaritmo de la concentraci\u00f3n de part\u00edculas suspendidas en aire y el tiempo transcurrido; por lo cual es posible comparar la cantidad de part\u00edculas internas y externas a la mascarilla o respirador en un mismo periodo y conocer el porcentaje de protecci\u00f3n respiratoria de cada muestra evaluada. Resultados: Se ha logrado implementar una metodolog\u00eda para evaluar el nivel de protecci\u00f3n respiratoria ante aerosoles menores a 5,0 \u03bcm. Asimismo, el empleo de accesorios como ligas o ajustadores detr\u00e1s de cabeza y nuca, y el uso de clips nasales robustos, incrementan significativamente el nivel de protecci\u00f3n respiratoria ante part\u00edculas con alta probabilidad de contener al SARS-CoV-2. Conclusiones: Se observa una concordancia entre los valores de protecci\u00f3n respiratoria obtenidos y los esperados, considerando el nivel de filtraci\u00f3n del material empleado de cada mascarilla quir\u00fargica o respirador, y su nivel de ajuste. Se observ\u00f3 un incremento significativo en los niveles de protecci\u00f3n respiratoria.<\/jats:p>","DOI":"10.17843\/rpmesp.2021.383.8036","type":"journal-article","created":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T17:24:46Z","timestamp":1635269086000},"page":"391-8","source":"Crossref","is-referenced-by-count":2,"title":["Metodolog\u00eda para evaluar el nivel de protecci\u00f3n respiratoria de mascarillas y respiradores ante part\u00edculas similares a las que transmiten el SARS-CoV-2"],"prefix":"10.17843","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9693-024X","authenticated-orcid":false,"given":"Manuel","family":"Chavez-Ruiz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5685-6658","authenticated-orcid":false,"given":"Lenin","family":"Rueda-Torres","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4288-5578","authenticated-orcid":false,"given":"Betsab\u00e9","family":"Ruffner-Camargo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0699-8708","authenticated-orcid":false,"given":"Cristofer","family":"Bellido-Achahui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7920","published-online":{"date-parts":[[2021,10,5]]},"container-title":["Revista Peruana de Medicina Experimental y Salud P\u00fablica"],"original-title":[],"link":[{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/viewFile\/8036\/4382","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/viewFile\/8036\/4382","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,10,26]],"date-time":"2021-10-26T17:25:18Z","timestamp":1635269118000},"score":1,"resource":{"primary":{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/view\/8036"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,10,5]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,8,11]]}},"URL":"https:\/\/doi.org\/10.17843\/rpmesp.2021.383.8036","relation":{},"ISSN":["1726-4642","1726-4634"],"issn-type":[{"type":"electronic","value":"1726-4642"},{"type":"print","value":"1726-4634"}],"subject":[],"published":{"date-parts":[[2021,10,5]]}}}
