|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
1. ? Dyspnoea improvement measured by MRC scale. 2.- Increase at least 27 meters of the distance of the 6 minutes walking test. 3. ? Increase of the physical activity measured by accelerometer. 4. - Adherence. Hours using oxygen (Visionox ® device). |
1.- Mejoría en la disnea medida por la escala MRC. 2.-Mejoría en la capacidad de esfuerzo: considerando como diferencia clínicamente significativa el incremento de, al menos, 26 metros en la distancia recorrida en la prueba de 6 minutos de la marcha. 3.- Actividad física medida con el acelerómetro. 4.- Cumplimiento. Se analizará contabilizando las horas de uso reportadas por el paciente, a través del total de oxígeno consumido en un tiempo determinado que se obtendrá de las empresas suministradoras, y de la utilización del dispositivo VisionOx®. |
