Experimental: Group 1, consisting of participants with COPD and usually using O2
In this group, in addition to the standard care, the participant undergoes the 6 Minute Walking Test (6MWT) using compressed medical air (RA) cylinders, believing that there is oxygen (O2) inside the cylinder.
The same, then, in addition to the standard care, is subjected to the execution of the 6 Minute Walking Test (6MWT), thanks to the use of cylinders of Oxygen (O2), believing that inside the cylinder there is Oxygen (O2).
The sequence of this group will then be characterised as follows: ABC (A=Baseline, B=Air, C=Oxygen).
|
During the 6 Minute Walking Test (6MWT), the participant will be required to walk as fast as possible on a flat, straight surface on the ward (e.g.
corridor) in six minutes, including as many breaks as he/she deems necessary.
The performance of this test will be monitored continuously by a Respiratory Physiotherapist and will include the presence of a Physician, who will be ready to assist as needed.
The sequence of use of compressed medical air and oxygen used during the 6MWT in the first group will then be characterised as follows: ABC (A=Baseline, B=Air, C=Oxygen).
The sequence of the second group will be characterised as follows: ACB (A=Baseline, B=Air, C=Oxygen).

Placebo-Komparator: Group 2, consisting of participants with COPD and usually not using O2
In this group, in addition to standard care, the participant is given the 6 Minute Walking Test (6MWT) using oxygen (O2) cylinders, believing that there is oxygen (O2) inside the cylinder.
Next, the participant undergoes the 6 Minute Walking Test (6MWT), using compressed medical air (RA) cylinders, believing that there is oxygen (O2) inside the cylinder.
The sequence of this group will be characterised as follows: ACB (A=Baseline, B=Air, C=Oxygen).

Feeling of fatigue, as measured by the Fatigue Severity Scale (FSS)
Zeitfenster: Changes from baseline at the FSS after the completion of the 6MWT performed using oxygen or compressed medical air. Up to 1 hour and half
|
Feeling of fatigue, as measured by the Fatigue Severity Scale (FSS).
The items are scored on a 7 point scale with 1=strongly disagree and 7=strongly agree.
The minimum score=9 and maximum score possible=63.
Higher the score=greater fatigue severity.

VAS Dyspnoea, measured by the British Medical Research Council's Modified Questionnaire (mMRC)
Zeitfenster: Change from baseline at the dyspnoea after the completion of the 6MWT performed using oxygen or compressed medical air. Up to 1 hour and half
|
VAS Dyspnoea, measured by the British Medical Research Council's Modified Questionnaire (mMRC).
The mMRC breathlessness scale ranges from grade 0 to 4.
