About
The aim of this study is to compare exercise capacity in COPD patients through two different systems of supplemental oxygen delivery: High Flow Nasal Cannula Oxygen (HFNCO) and The Venturi Mask (VM).
Full description
Design: interventional, crossover, randomized.
The main goal of this study is to compare the maximum speed reached in an Incremental Load Treadmill Test (ILTT) and max time tolerated in a Constant Treadmill Load Test (CTLT) while using two different oxygen delivery devices (High Flow Nasal Cannula Oxygen and The Mask Venturi).
Patients will be evaluated through two different kinds of tests: Incremental Load Treadmill Test (ILTT) and Constant Treadmill Load Test (CTLT). Each test will be conducted two times, once using HFNCO and the other time with The VM.
In total, each patient will be evaluated four times on four different visits. The testing order will be randomized through STATA.
The following variables will be measured before, during and after each test:
