Brief Summary

Chronic Obstructive Pulmonary Disease (COPD) is associated with high morbidity and mortality. The Danish Lung Association estimates that 320,000 Danes live with COPD, of which approximately 50,000 with severe COPD. In 2017, records showed that 23,979 admissions in Denmark were related to COPD; of these patients, about 20% were readmitted 2-30 days after discharge. The main symptom is dyspnea, which is often accompanied by anxiety. Primary treatment is; oxygen, bronchiolitis, prednisolone, morfica, NIV, and anxiolytics. Researchers at Hvidovre Hospital have developed an oxygen robot that continuously monitors the patient's SaO2 (oxygen saturation) and automatically administrates the oxygen depending on it. The preliminary results show that patients with robot-administrated oxygen were within defined SaO2 range in 85.7% of the time versus 46.6% when oxygen was nurse-administrated. The research was conducted as a multicentre Randomized Controlled Trial focusing on physiological end-points. There is a lack of knowledge about the patient perspective of treatment with the oxygen robot. The purpose of this study is: 1\. To examine the effect of robot-administered oxygen on patients' perception of dyspnoea, including the emotional response in the form of anxiety and depression The perspective is to be able to provide a holistic response to whether robot-administered oxygen can be a better method of treating and alleviating dyspnoea.

Outcome Measures

Primary Outcomes (1)

• Global dyspnea measured on scale A1 on multidimensional Dyspnea Profile (MDP)

  Multidimensional Dyspnea Profile (MDP) is validated for patients with COPD (40) The schedule is an instrument consisting of 11 rating scales that describe both the sensory and emotional dimension of dyspnea in a user-specified focus period.Patients perception of unpleasantness or discomfort in breathing sensations described as global dyspnea measured on an intensity scale from 0 (anchored by term; neutral) -10(anchored by term; unbearable )

  3 days

Secondary Outcomes (4)

• The sensory dimension of dyspnea

  3 days

• The emotional dimension of dyspnea

  3 days

• Current dyspnea

  3 days

• Accumulated dyspnea

  3 days

Other Outcomes (4)

• Respiratory symptom intensity

  3 days

• anxiety

Study Arms (2)

Active

ACTIVE COMPARATOR

Usual care plus O2matic controlled oxygen therapy for a maximum of 3 days or until weaning from oxygen supplementation

Device: O2matic

controle

NO INTERVENTION

Usual care plus manual controlled oxygen therapy by nursing staff. O2matic used in monitoring mode to measure SpO2 continuously

Interventions

O2matic DEVICE

O2matic is a closed-loop-system that controls oxygenadministration according to SpO2. The aim is to maintain SpO2 within a predefined target interval, E.G. 88-92% with the lowest possible supplementation of oxygen by nasal cannula
