The aim of this study was to assess the effect of different mask types on clinical parameters during moderate exercise in healthy non-smokers, active smokers and patients with interstitial lung disease (ILD) without the need of oxygen therapy.<\/jats:p><jats:p>In a prospective observational pilot study participants performed a six-minute walk test without mask, with a surgical mask, a well-fitted FFP2 mask and with a valved FFP3 mask. Respiratory rate, blood pressure, heart rate, blood gas analysis parameters, dyspnoea and six-minute walk distance were measured. Data were analysed in an ANOVA model.<\/jats:p><jats:p>21 healthy participants, 17 active smokers without known pulmonary disease and 15 patients with interstitial lung disease were included. Participants with ILD had a significant lower walking distance, a higher respiratory rate and a lower pO2 when using FFP2 masks, but not with valved FFP3 masks or surgical masks compared to not wearing a mask.<\/jats:p><jats:p>For patients with ILD without the need of oxygen therapy wearing an FFP2 mask had a negative impact on pO2, respiratory rate and walking distance in the six-minute walk test.
