This is an interventional basic science trial for Lung Diseases, Interstitial
Eligibility Criteria
Inclusion Criteria:
- COLD with forced expiratory volume at one second (FEV1) <50%, without long term oxygen therapy

Exclusion Criteria:
- comorbidity which decreases cognitive function
- comorbidity which decreases concentration

Outcomes
Primary Outcome Measures
Standard deviation from the centre of the road
Measuring how far from the centre of the road the patient has been driving in the driving simulation
Number of nil responses
Measuring the number of times the patients doesn't react to the number "2" on the screen
Response time
Measuring the mean amount of response time from the number "2" appears on the screen until the patient reacts
Number of off-road events per hour
The number of times the car is off-road during the driving simulation

5. Study Description
Brief Summary
The objective is to study the cognitive functions in patients with chronic obstructive lung disease (COLD) and patients with interstitial lung disease (ILD) compared to healthy controls. The cognitive functions are tested with and without oxygen therapy to clarify the effect of oxygen therapy. Driving simulations is used to test the cognitive functions.
The hypothesis is that patients with chronic lung disease have decreased cognitive functions and that oxygen therapy will increase their cognitive functions.
