Effects of surgical and FFP2/N95 face masks on cardiopulmonary exercise capacity |pdf=|usr=}}{{32632523}} gab.com Text Effects of surgical and FFP2/N95 face masks on cardiopulmonary exercise capacity JO: Clin Res Cardiol http://www.kidney.de/pget.php?&tw=1&pmid=32632523 #FOAvip BACKGROUND: Due to the SARS-CoV2 pandemic, medical face masks are widely recommended for a large number of individuals and long durations. The effect of wearing a surgical and a FFP2/N95 face mask on cardiopulmonary exercise capacity has not been systematically reported. METHODS: This prospective cross-over study quantitated the effects of wearing no mask (nm), a surgical mask (sm) and a FFP2/N95 mask (ffpm) in 12 healthy males (age 38.1 +/- 6.2 years, BMI 24.5 +/- 2.0 kg/m(2)). The 36 tests were performed in randomized order. The cardiopulmonary and metabolic responses were monitored by ergo-spirometry and impedance cardiography. Ten domains of comfort/discomfort of wearing a mask were assessed by questionnaire. RESULTS: The pulmonary function parameters were significantly lower with mask (forced expiratory volume: 5.6 +/- 1.0 vs 5.3 +/- 0.8 vs 6.1 +/- 1.0 l/s with sm, ffpm and nm, respectively; p = 0.001; peak expiratory flow: 8.7 +/- 1.4 vs 7.5 +/- 1.1 vs 9.7 +/- 1.6 l/s; p < 0.001). The maximum power was 269 +/- 45, 263 +/- 42 and 277 +/- 46 W with sm, ffpm and nm, respectively; p = 0.002; the ventilation was significantly reduced with both face masks (131 +/- 28 vs 114 +/- 23 vs 99 +/- 19 l/m; p < 0.001). Peak blood lactate response was reduced with mask. Cardiac output was similar with and without mask. Participants reported consistent and marked discomfort wearing the masks, especially ffpm. CONCLUSION: Ventilation, cardiopulmonary exercise capacity and comfort are reduced by surgical masks and highly impaired by FFP2/N95 face masks in healthy individuals. These data are important for recommendations on wearing face masks at work or during physical exercise.
