- Primary Outcome Measures
Name Time Method Outcome found 1: A difference of 357 s (95% confidence interval – CI 181 – 533 s; p = 0.001) was found in exercise tolerance between the time achieved in the endurance test performed with the high-flow nasal cannula (937 s, 95% CI 668 – 1205 s) and the time achieved in the endurance test performed with the Venturi mask (580 s, 95% CI 403 – 756 s).;Expected outcome 1: It is expected to find a difference of at least 109 seconds in exercise tolerance between the time achieved in the endurance test performed with the high-flow nasal cannula and the time achieved in the endurance test performed with the Venturi mask.
- Secondary Outcome Measures
Name Time Method Expected outcome 2: Absence of difference in the comparison of changes between pre- and post-endurance test, in physiological variables such as symptoms of dyspnea and lower limb fatigue, respiratory rate, peripheral oxygen saturation, heart rate, blood pressure and peripheral blood lactate level , between the two oxygen systems (high-flow nasal cannula and Venturi mask).;Outcome found 2: There was no statistically significant or clinically important difference in the comparison of changes between pre- and post-endurance test, in physiological variables such as symptoms of dyspnea and lower limb fatigue, respiratory rate, peripheral oxygen saturation, heart rate, blood pressure and peripheral blood lactate level, between the two oxygen systems (high-flow nasal cannula and Venturi mask).
