no mask use vs. surgical mask use vs. N95 mask use Participants underwent exercise testing on a cycle ergometer with a ramp protocol. initial load of 25 W at a constant speed of 55-65 rpm The initial load was increased by 25 W every 3 min until exhaustion. six tests, with a minimum rest period of 24 h between tests A 12-lead ECG was used in order to assess HR, SaO2, and BP. RR was noninvasively assessed by means of nasal prongs. |
