Abstract
Objective: This study aimed to compare physiological changes when wearing a N95 and surgical mask at rest.
Methods: 42 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. VO2, VCO2, and RER were measured. RR, MV, and HR were recorded using Hexoskin Smart Shirt apparatus. Testing consisted of 3 15-minute trials: no mask, surgical mask, and a N95 respirator. RPE was assessed. Results were analyzed using separate repeated measures ANOVAs.
Results: RER, MV, and RPE were significantly higher in both conditions. Highest RPE reported while wearing the N95 mask.
Conclusion: 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.
