Description:
Lung disease is the leading cause of occupation-related illnesses in the United States. To address this issue, an estimated 5 million workers rely on respiratory devices to protect themselves. However, it is critical that they are properly trained to consistently don and doff a mask correctly. Currently, there are only a few documented training strategies employed and their effectiveness for respiratory protection has largely been unchallenged. Therefore, this study aims to compare the efficacy of two popular training strategies: one-on-one training and video training. 20 subjects were recruited for this study and stratified into two groups based on the type of training they received. Group 1 received training by a pre-recorded video and Group 2 received one-on-one training by me. All participants received unassisted quantitative fit tests before and post-training. With a 30% passing rate, Group 1 had no statistically significant improvements in fit test results after training (P = 0.130). In contrast, 80% of Group 2 participants were able to pass a fit test post-training (P = 0.024). When passing rates post-training for Group 1versus Group 2 were compared, there was no significant difference (P= .139). These findings are consistent with the literature, suggesting that in-person strategies may only serve to enhance the training experience. Furthermore, a larger sample size is needed to better understand the role of training strategies in respirator fit over time.
Situation/Problem:
To date, there are few training strategies employed for respiratory protection, including training videos, one-on-one training by trained professionals, pamphlets, and classroom instruction. Current literature suggests that employees who don a respirator without the assistance of a trained professional, are more likely to have an improperly fitted respirator and, therefore, be less protected. This leads us to hypothesize that training methods may influence respirator fit over time. This study aims to compare two training strategies and the effect of such preparation on respirator fit.
Methods:
20 subjects were recruited for this study and stratified into two groups based on the type of training they received. Group 1 received training by a pre-recorded video and Group 2 received one-on-one training by me. The N95 flat-fold single-use disposable particulate FFR (3M VFlex Model 1804 and 1804s) used in this study comes in sizes small and regular. To select the appropriate size, before experimental procedures, subject facial dimensions were measured. Following, participants received an unassisted quantitative fit test. Subjects then underwent their respective training session and received a final unassisted quantitative fit test post-training.
Results / Conclusions:
3 out of 10 subjects that underwent video training (group 1), were able to pass a fit test. This is an insignificant increase, compared to the 1 out of 10 that passed a fit test prior to receiving training (P = 0.130). In comparison 80% of participants undergoing one-on-one training (Group 2), were able to pass a fit test post-training (P = 0.024). However, when passing rates post-training for Group 1versus Group 2 were compared, there was no significant difference (P= .139).
