Automated Oxygen Delivery by O2matic to Patients Admitted With an Exacerbation in COPD

Brief Summary

The aim of the study is to examine if automated oxygen delivery with O2matic is better than manually controlled oxygen therapy for patients admitted to hospital with an exacerbation in Chronic Obstructive Pulmonary Disease (COPD). O2matic is a closed -loop system based on continuous non-invasive measurement of pulse and oxygen-saturation that is processed in an algorithm that controls the flow of oxygen to the patient. The primary hypothesis is that O2matic increases time within acceptable oxygen-saturation interval. Secondary hypotheses are that O2matic compared to manual control reduces time with severe hypoxia (SpO2 \< 85 %), hypoxi (SpO2 below intended interval) and hyperoxia (SpO2 above intended interval).
