The use of respiratory protection remains important in protecting health care workers from airborne pathogens such as viruses. Respirator supply is constantly changing with new models regularly becoming available. Health services should consider a broad range of factors when procuring respirators, including the results of quantitative fit testing in a representative sample of the workforce. Subjective comfort factors and compatibility with a variety of workplace tasks, such as suitability for staff use near magnetic resonance imaging (MRI) environments where relevant, should also be considered. This article compares the quantitative fit factors and user assessments for two styles of flat-fold cup respirators, Care Essentials (CE) MSK-002 P2 and BYD DE2322 N95.
Quantitative fit tests (QNFT) were performed on 300 participants on each model of respirator in this randomised crossover trial. Participants then completed a questionnaire on their assessments of each respirator.
The Care Essentials MSK-002 had a significantly higher quantitative fit test pass rate than the BYD DE2322 (57% vs 18%, p < 0.001). There was no concordance between fit test pass rates for each model. Additionally, the Care Essentials MSK-002 achieved significantly higher scores on each of the responses in the subjective usability survey.
It is recommended that the Care Essentials MSK-002 be made available for health care use due to higher QNFT pass rates, higher subjective usability assessment scores, plus its potential for use in MRI environments when compared to the BYD DE2322.
使用呼吸防护用品对于保护医护人员免受病毒等空气传播病原体的侵害仍然至关重要。呼吸器的供应不断变化，新的型号经常上市。卫生服务机构在采购呼吸器时应考虑广泛的因素，包括在具有代表性的工作人员样本中进行定量适合性测试的结果。还应考虑主观舒适度因素以及与各种工作场所任务的兼容性，例如在相关的磁共振成像（MRI）环境附近工作人员使用的适用性。本文比较了两种扁平折叠杯式呼吸器（Care Essentials（CE）MSK - 002 P2和比亚迪DE2322 N95）的定量适合性因素和用户评估。
在这项随机交叉试验中，对每种呼吸器型号的300名参与者进行了定量适合性测试（QNFT）。参与者随后完成了一份关于他们对每种呼吸器评估的问卷。
Care Essentials MSK - 002的定量适合性测试通过率显著高于比亚迪DE2322（57%对18%，p < 0.001）。每种型号的适合性测试通过率之间没有一致性。此外，Care Essentials MSK - 002在主观可用性调查的各项回答中均获得了显著更高的分数。
建议将Care Essentials MSK - 002用于医疗保健用途，因为与比亚迪DE2322相比，它具有更高的QNFT通过率、更高的主观可用性评估分数，以及在MRI环境中使用的潜力。
