Evaluation of N95 respirator use as a tuberculosis control measure in a resource-limited setting.
SETTING A 150-bed public Brazilian hospital that serves as reference hospital for tuberculosis (TB) patients. OBJECTIVE To evaluate the use of personal respiratory protection by health care workers (HCWs) as a measure to reduce TB occupational risk. DESIGN One hundred and forty-five HCWs were randomly observed for the use of a N95 respirator when entering high-risk areas or performing high-...
متن کاملHeadform and N95 filtering facepiece respirator interaction: contact pressure simulation and validation.
This article presents a computational and experimental study of contact pressure between six N95 filtering facepiece respirators (FFRs) and five newly developed digital headforms (small, medium, large, long/narrow, and short/wide). Contact interaction is simulated using the finite element method and validated by experiments using a pressure mapping system. The headform model has multiple layers...
متن کاملEffect of upper strap downward displacement on n95 filtering facepiece respirator fit factors: a pilot study.
Fifteen subjects underwent three replicates of quantitative respirator fit-testing with N95 filtering facepiece respirators that were donned with the upper strap high on the occiput, as per the manufacturers' donning instructions. Each fit-test was immediately followed by repeat fit-testing with the upper strap downwardly displaced to the level of the ear sulcus to determine any change in fit f...
متن کاملSurgical mask vs N95 respirator for preventing influenza among health care workers: a randomized trial.
CONTEXT Data about the effectiveness of the surgical mask compared with the N95 respirator for protecting health care workers against influenza are sparse. Given the likelihood that N95 respirators will be in short supply during a pandemic and not available in many countries, knowing the effectiveness of the surgical mask is of public health importance. OBJECTIVE To compare the surgical mask ...
متن کاملLarge particle penetration through N95 respirator filters and facepiece leaks with cyclic flow.
The aim of this study was to investigate respirator filter and faceseal penetration of particles representing bacterial and fungal spore size ranges (0.7-4 mum). First, field experiments were conducted to determine workplace protection factors (WPFs) for a typical N95 filtering facepiece respirator (FFR). These data (average WPF = 515) were then used to position the FFR on a manikin to simulate...
