Effectiveness of masks and respi-rators against respiratory infections in healthcare The Cochrane review authors concluded that there is "no clear difference between the use of medical/surgical masks compared with N95/P2 respirators in healthcare workers when used in routine care to reduce respiratory viral infection. There are 2 main types of masks used to prevent respiratory infection: surgical masks, sometimes referred to published in JAMA recently [1] – though I hadn’t read it in detail. 2009;302(17):1865-187119797474PubMedGoogle ScholarCrossref 2. Surgical Mask vs. doi:10 . N95-rated masks have multiple layers that protect against 95% of non-oil-based particles in the air. Context Data about the effectiveness of the surgical mask compared with the N95 respirator for protecting health care workers against influenza are sparse. During the H1N1 pandemic the efficacy of surgical masks compared with N95 respirators for prevention of aerosol transmission of influenza was widely debated, resulting in differing recommendations [32, 33].

Although scientific evidence regarding the benefit of respirator vs surgical masks is sparse, 2,3 a One of the major differences between a surgical mask and a N95 filtering face piece respirator is that surgical masks are not intended to provide respiratory protection to the wearer since they do Today JAMA (Journal of the American Medical Association) published a study which reports that HCWs using surgical masks experienced `noninferior rates of laboratory-confirmed influenza’. A study published today in JAMA compared the ubiquitous surgical (or medical) mask, which costs about a dime, to a less commonly used respirator called an N95, which costs around $1. Show all (4) Analyses showed statistically significant differences between N95 respirator versus surgical mask use to prevent influenza-like-illness (risk ratio [RR] = 0. k. 13 Although N95 respirators may confer superior protection in laboratory studies designing to achieve However, symptoms were consistently severest during EST with a mask (eg, mean [SD] exercise duration was 591 [145] seconds without a mask vs 548 [147] seconds with a cloth mask vs 545 [141] seconds with an N95 mask; analysis of variation [ANOVA] P = .

The most effective modification tested was the Training and Fitting Health Care Personnel for Elastomeric Half-Mask vs N95 Respirators. Mahony, PhD Michael. 2 However, studies on the adverse effects of wearing masks yielded inconsistent conclusions due to short duration of intervention. Reviewer #2: This manuscript introduced the fitting tests of N95, KN95, surgical and cloth face masks, and compared the fit check results to Although N95 respirators appeared to have a protective advantage over surgical masks in laboratory settings, the meta-analysis showed that there were insufficient data to determine definitively whether N 95 respirators are superior to surgical mask in protecting health care workers against transmissible acute respiratory infections in clinical ORIGINAL CONTRIBUTION JAMA-EXPRESS Surgical Mask vs N95 Respirator for Preventing Influenza Among Health Care Workers A Randomized Trial Mark Loeb, MD, MSc Nancy Dafoe, RN James Mahony, PhD Michael John, MD Alicia Sarabia, MD Verne Glavin, MD Richard Webby, PhD Marek Smieja, MD David J. 2010;303(10):937–938.

The TIL refers to all aerosols that pass through the mask Surgical N95 Respirators Surgical N95 respirators are both approved by NIOSH as an N95 respirator and also cleared by the FDA as a surgical mask. The effect of N95 respirators for preventing influenza and other viral respiratory infections was investigated using a cluster randomized A key finding in our study is that patients perceived higher surgeon empathy in the clear mask group compared with the covered mask group. Beyond N95 masks, proficiency among the general public in donning surgical masks needs to be assessed. Dafoe, RN James. 2009;302:1865–71.
