背景：呼吸器与使用者脸部的贴合程度是影响其有效性的重要因素。 目的：本研究的目的是调查伊朗设拉子医科大学附属六家教育医院的医护人员 (HCW) 对 N95/FFP2 呼吸器的定性贴合情况。 方法：这项横断面研究对 284 名医护人员进行。他们使用中型平折FFP2呼吸器（3M - 型号；8222和SPC - 型号；8226）和杯形N95呼吸器（3M - 型号；8210）。首先，全体员工填写了体检评估问卷。定性贴合测试由 JSP 套件（英国牛津）进行。使用游标卡尺测量呼吸器装配时的关键面部人体测量尺寸。所有数据分析均使用SPSS 21版和STATA 13进行。结果：在本研究中，只有10.6%的参与者通过了定性拟合检验。与平折式呼吸器相比，杯形呼吸器具有更好的贴合性。使用 N95 口罩的人中，共有 10.2% 的人不具备佩戴口罩的医疗能力。大多数通过密合性测试的个体被置于密合性测试 NIOSH 双变量面板的中型单元 (10%) 中。结论：所研究的中型 N95/FFP2 呼吸器无法在伊朗医护人员的面部上提供适当的贴合性。需要对伊朗市场上不同尺寸和型号的现有呼吸器进行更多研究，以找到最适合伊朗医护人员的呼吸器。
Background: How tight fitting respirators fit on the users face is an important factor in their effectiveness.Objectives: The aim of this study was to investigate the qualitative fitting of N95/FFP2 respirators among Health Care Workers (HCWs) in six educational hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran.Methods: This cross - sectional study was carried out on 284 HCWs. They were using medium size respirators of flat - fold FFP2 (3M - model; 8222 and SPC - model; 8226) and cup - shaped N95 respirators (3M - model; 8210). At first, a medical evaluation questionnaire was completed by all employees. Qualitative fit testing was performed by JSP kit (Oxford, England). Critical face anthropometric dimensions in fitting of respirators were measured using sliding caliper. All data analysis was performed with SPSS version 21 and STATA 13.Results: In this study, only10.6% of the participants passed the qualitative fit test. Cup - shaped respirators had better fitting compared to flat - fold respirators. A total of 10.2% of the individuals who were using N95 respirators were not medically competent to wear a respirator. Most individuals who passed the fit test were placed in the medium cell (10%) of fit testing NIOSH Bivariate panel.Conclusions: Studied medium size of N95/FFP2 respirators could not provide proper fitting on the face of Iranian HCWs. More studies with different sizes and models of available respirators in the Iran market is required to find the most appropriate respirators to provide proper fit on Iranian HCWs.
