This study aimed to compare physiological changes when wearing a N95 and surgical mask at rest.
Forty-two subjects aged 18-55 (19 males; age 22.98 ± 3.83) were recruited. Respiratory and metabolic data were collected using indirect calorimetry under a hood. Volume of oxygen consumed, volume of CO 2 produced, and respiratory exchange ratio were measured. Respiratory rate, minute ventilation, and heart rate were recorded using Hexoskin Smart Shirt apparatus. Testing consisted of the following three 15-minute trials: no mask, surgical mask, and a N95 respirator. Rating of perceived exertion (RPE) was assessed. Results were analyzed using separate repeated measures analyses of variance.
Respiratory exchange ratio, minute ventilation, and RPE were significantly higher in both conditions. Highest RPE reported while wearing the N95 mask.
The use of a surgical or N95 face mask can cause small metabolic, respiratory, and RPE changes. Minor physiological changes were observed but remained within normally expected physiological parameters at rest.
本研究旨在比较静息状态下佩戴N95口罩和外科口罩时的生理变化。
招募了42名年龄在18 - 55岁之间的受试者（19名男性；年龄22.98±3.83）。使用面罩下的间接量热法收集呼吸和代谢数据。测量耗氧量、二氧化碳产生量和呼吸交换率。使用Hexoskin智能衬衫设备记录呼吸频率、分钟通气量和心率。测试包括以下三个15分钟的试验：不戴口罩、戴外科口罩和戴N95口罩。评估主观用力程度（RPE）。结果采用单独的重复测量方差分析进行分析。
在两种情况下，呼吸交换率、分钟通气量和RPE均显著升高。佩戴N95口罩时报告的RPE最高。
使用外科口罩或N95口罩会引起轻微的代谢、呼吸和RPE变化。观察到了轻微的生理变化，但仍在静息状态下正常预期的生理参数范围内。
