Primary Outcome Measures

Name	Time	Method
Evaluate the difference in the distance walked between the six-minute walk test (6MWT) with and without continuous monitoring of peripheral oxygen saturation (SpO2) in patients with chronic respiratory diseases, using the 6MWT method, which are not the requirements with respiratory disease chronic disease will be randomized to one of the protocols: A) WITH continuous monitoring of SpO2, or B) WITHOUT continuous monitoring of SpO2. In order to have the statistical power to detect a difference of 30 meter with standard deviation 90 meters between the tests performed with and without continuous SpO2 monitoring, it intends to include a minimum sample of 143 participants in each group. Anticipating possible losses and unsatisfactory collections, we planned the final inclusion of 300 participants. So we will observe if there is a difference in the distance covered in the 6MWT between the groups
