Outcome Measures

Primary Outcomes (1)

  • Time used for the Glittre-ADL test

    Change in time used to complete the Glittre-ADL test with automated titration compared to fixed-dose treatment

    Immediately after intervention (control arm test and automated oxygen titration arm) on the same day

Secondary Outcomes (3)

  • Dyspnea

    Immediately after the intervention

  • Saturation

    Immediately after the intervention

  • Oxygen consumption

    Immediately after the intervention

Study Arms (2)

Usual oxygen dose

NO INTERVENTION

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

Automated oxygen dose

EXPERIMENTAL

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

Other: Automated oxygen titration based on the oxygen saturation during activity

Interventions

A device will be used, which automatically adjusts the oxygen flow to the dosage necessary for keeping the saturation at the recommended level (90-94%). If the saturation falls below 90%, oxygen flow will increase, and if the saturation increases above 94%, oxygen flow decreases in order to stay on target.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Verified history of COPD with FEV1/FVC \< 0.70 and FEV1 \< 50 %
  • Hypoxemic at rest (SpO2≤ 90 %) and fulfilment of general national criteria for LTOT
  • Partial pressure of Oxygen (PaO2) (without oxygen supplement) ≤7.3 kPa in clinically stable and optimally treated condition
  • Increase in PaO2 after oxygen supplementation (to 8.0-9.0 kPa) without decrease in arterial pH (\> 0.03 kPa)
  • The oxygen is used at least 15 hours daily (optimally 24 hours daily)
  • The treatment is handled by hospital departments with lung medical expertise.
  • Able to walk at least 30 meters

You may not qualify if:

  • Pulmonary or cardiac condition other than COPD limiting physical performance
  • Unstable heart condition or stenotic aortic valve disease
  • A physical condition including paralysis, lower extremity pain, or back problem limiting physical performance
  • Exacerbation in COPD treated with either antibiotics or prednisolone within the last 3 weeks
