Component Analysis of Respirator User Training

Abstract

Respirators must be properly used to be effective. In an experimental protocol, 145 subjects were trained and then observed donning and doffing respirators. Filtering facepiece and dual cartridge half face mask types were studied. Subjects were then tested for knowledge and for proper performance using video recording analysis. Knowledge tests showed adequate learning, but performance was often poor. Inspection, strap tension (half mask), seal checking, and avoiding mask contact during doffing were particularly problematic. Mask positioning was generally well done. Correlation between knowledge and performance for specific items was generally poor, although there was a weak correlation between overall knowledge and overall performance (rho = 0.32) for the half mask users. Actual unprompted performance as well as knowledge and fit-testing should be assessed for user certification. Respirator design approval should consider users' ability to learn proper technique.

Potential Role of Infrared Imaging for Detecting Facial Seal Leaks in Filtering Facepiece Respirator Users

“…The current study systematically incorporates a large group of individuals who participated in a research project, including a wider range fit adequacy. (5,7,8) The analyses indicate that IRI has potential as an adjunct to traditional fit-testing methods, but the technique does not appear likely to supplant the other methods. As seen in Table III, IRI was able to detect leakage associated with low FFs.…”

“…Details of the study are described elsewhere. (5,7,8) Research subjects with minimal or no respirator experience were randomized to three training methods. The study included two distinct protocols, but each subject participated in only one.…”

Comparison of fit factors among healthcare providers working in the Emergency Department Center before and after training with three types of N95 and higher filter respirators

“…We showed them how to wear respirators in a multistep process: (1) donning it correctly, (2) making adjustments for a secure facial seal, (3) confirming the fit, and (4) properly removing it. [27] The participants followed each step and received feedback immediately. The fit check (also known as seal check) is a procedure advocated by CDC, a self-check the wearer performs to detect air leakage of the respirator.…”

Endotracheal Intubation Using a Direct Laryngoscope and the Protective Performances of Respirators: A Randomized Trial

“…Or et al have demonstrated that training undergraduate nursing students to properly fit their respirators increased the likelihood of proper respirator use [23]. A component analysis of respirator user training revealed that adequate knowledge alone did not ensure proper respirator use in clinical practice [24]. In the present study, all participants received real-time feedback after their respirator training based on the manufacturer's manual.…”
