Abstract：
Respiratory droplets, naturally produced during expiration, can transmit pathogens from infected individuals. Wearing a face mask is crucial to prevent such transmission, yet the perception of dyspnea and uncomfortable breathing remains a common concern, particularly during epidemics. The aim of this study was to investigate the impact of face mask use on the perception of dyspnea, cardiopulmonary parameters, and facial temperature during physical activity. A randomized crossover study was conducted on healthy adults at a physiology laboratory located in the Faculty of Medicine, Universitas Sumatera Utara, Medan, Indonesia, in November 2022. Participants underwent five stages of physical exercise tests based on the Bruce Protocol under three conditions: without any face mask (control), wearing a surgical mask, and an N95 mask, forming the study\'s main groups. Dyspnea perception (measured by the Modified Borg Dyspnea Scale), cardiopulmonary parameters (heart rate, oxygen saturation, respiratory rate, blood pressure, and mean arterial pressure) and facial temperature were measured before the exercise test (pre-workout), at the end of stage 1, 2, 3, 4, 5, and after the whole exercise test (post-workout). A two-way repeated measures ANOVA was conducted, considering two factors: the type of mask (control, surgical mask, N95 mask) and the various stages of the exercise test. A total of 36 healthy adults were included in the study. We found that dyspnea perception was much worse in the N95 mask group, particularly during vigorous exercise. There was no significant difference between groups in cardiopulmonary parameters. However, participants wearing N95 had a greater supralabial temperature than those wearing surgical masks or no mask at all. It is recommended to undertake a more in-depth evaluation of cardiopulmonary physiological measures.
摘要：
呼吸道飞沫,在到期期间自然产生，可以从被感染的个体传播病原体。戴口罩对于防止这种传播至关重要，然而，呼吸困难和呼吸不舒服的感觉仍然是一个常见的问题，特别是在流行病期间。这项研究的目的是调查使用面罩对呼吸困难的感知的影响，心肺参数，和身体活动时的面部温度。在医学院的生理学实验室对健康成年人进行了随机交叉研究，乌塔拉苏门答腊大学，棉兰,印度尼西亚,2022年11月。参与者在三种条件下进行了基于布鲁斯协议的五个阶段的体育锻炼测试：没有任何面罩（对照），戴着外科口罩,还有一个N95面具,形成研究的主要群体。呼吸困难感觉（通过改良的Borg呼吸困难量表测量），心肺参数(心率，氧饱和度,呼吸频率,血压,和平均动脉压）和面部温度在运动测试（锻炼前）之前测量，在阶段1、2、3、4、5结束时以及整个运动测试后（锻炼后）。进行了双向重复测量方差分析，考虑两个因素：面罩的类型(控制，外科口罩,N95面罩)和运动测试的各个阶段。共有36名健康成年人被纳入研究。我们发现N95面罩组的呼吸困难感觉要差得多，特别是在剧烈运动期间。两组之间的心肺参数没有显着差异。然而,佩戴N95的参与者的阴唇上温度高于佩戴外科口罩或根本不佩戴口罩的参与者.建议对心肺生理措施进行更深入的评估。
