Abstract
PEIDRO, ROBERTO et al. Exercise Testing Tolerance when Using Face Mask. Rev. argent. cardiol. [online]. 2021, vol.89, n.5, pp.466-469. Epub Oct 01, 2021. ISSN 1850-3748. http://dx.doi.org/10.7775/rac.es.v89.i5.20450.
Background:
Tolerance to exercise with the use of face mask is not well known.
Objective:
The aim of this study was to investigate the tolerance of exercise parameters during exercise stress testing (EST) while wearing a face mask.
Methods:
Multicenter study of EST while wearing face mask.
Results:
118 ESTs (62 on treadmill, 56 on cycle ergometer), 68 men, age 46.74 ± 16.7 years. Seventy patients (59.3%) completed the EST wearing a face mask, and 48 (40.7%) removed it; 17 patients (27.4%) were on treadmill and 31 (55.4%) on cycle ergometer (p = 0.002). Percentage of maximum predicted heart rate attained when the patients removed their face mask: 94.5 ± 5.35%. Age of those who removed the face mask: 42.69 ± 17.35 years and of those who tolerated the face mask: 49.51 ± 15.88 years (p = 0.003). Baseline SpO2 was 97.46 ± 1.01% and 96.58 ± 1.37% on peak exercise wearing face mask (p < 0.0001). SpO2 when the face mask was removed: 97.06 ± 1.35% (p <0.0001). Younger age and use of cycle ergometer were predictors of intolerance to face mask.
Conclusion:
Most patients completed peak exercise with face mask. Exercise intensity was high when the face mask was removed. Oxygen saturation dropped during exercise with face mask without clinical impact.
