Long term oxygen therapy (LTOT) increases the life span of patients with chronic obstructive pulmonary disease who have low oxygen levels. However, even when on oxygen therapy at home, from time to time patients still have low oxygen levels especially when walking which can be harmful. The investigators have designed a new system of delivering oxygen to overcome the above problem. The system measures the oxygen saturations of a patient and subsequently adjust the flow of oxygen to meet a pre-set oxygen saturation target. Hypothesis: the investigators intelligent oxygen therapy system is better at reducing low levels of oxygen during a 6 minute walk than usual ambulatory oxygen for patients with chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | The percentage of time spent with oxygen saturation below 90% | The participants complete three 6 minute walk tests. There is continuous oxygen saturation monitoring throughout the walk. At the completion of the walk, the percentage of time spent below an oxgen saturation of 90% is calculated | Assessed at the completion of the 6 minute walk test/s | |
Secondary | Total distance walked | Assessed at the completion of the 6 minute walk test | ||
Secondary | Mean oxygen saturation | Assessed during the 6MWT | ||
Secondary | Total Volume of oxygen delivered | The system records the outflow of oxygen every second. From this data, I can calculate the total volume of oxygen delivered to the patient. | Assessed at the completion of the 6 minute walk test |
