Automated Oxygen Titration in Daily Life in Patients With COPD on Home Oxygen (DaiLiHOT_1)
COPD (Chronic Obstructive Pulmonary Disease)
About this trial
This is an interventional treatment trial for COPD (Chronic Obstructive Pulmonary Disease) focused on measuring Activity, Automated oxygen titration, ADL, long term oxygen treatment
Eligibility Criteria
Inclusion Criteria:

Usual oxygen dose
Automated oxygen dose
A Glittre-ADL tests will be performed and the patients will use their usual fixed dose of oxygen. Pulse rate and saturation will continuously be registered during the test. Before, and after the Glittre-ADL, the patients will be asked the rate their level of dyspnea using Borg Dyspnea Scale
A Glittre-ADL tests will be performed and the patients will use automated oxygen titration set at an SpO2-target of 90 to 94 % and an oxygen flow of 0 - 8 liters/min. Pulse rate, oxygen flow rate and saturation will continuously be registered during the test. Before, and after the Glittre-ADL, the patients will be asked the rate their level of dyspnea using Borg Dyspnea Scale
