Approximately 1 in 5 (or 12.7 million adults) in the UK have longstanding respiratory illnesses, and 6.5 million patients report taking prescription medication to ease the burden. Many patients suffer from lung tissue damage, which impairs adequate blood oxygenation and reduces blood saturations, and causes breathlessness. The current method of treatment is palliative - with the patient breathing supplemental oxygen through an oxygen cylinder and tube. This severely compromises patients' quality of life, as they are tethered to a heavy, unwieldy oxygen cylinder, limiting their ability and willingness to leave home. Several recent studies in both animals and humans have indicated that orally administered oxygenated nanobubbles is a safe intervention that can improve tissue oxygenation. This randomized, double-blinded, cross-over, placebo-controlled study will evaluate the effect of an oxygen nanobubbles drink on the exercise performance of patients with chronic lung disease, such as pulmonary fibrosis. Patients will conduct the 6 Minute Walk Test (6MWT) twice, once with a placebo drink and once with the oxygen nanobubbles drink, based on a double-blind randomization protocol, and this study will evaluate the distance walked, heart rate, oxygen levels, breathlessness, and time to recovery in both cases. The investigators hypothesize that drinking the oxygen nanobubbles drink will improve the delivery of oxygen to vital organs, improving the distance a patient can cover in the 6 Minute Walk Test by 30m, which is the minimum clinically important difference.

Experimental: Oxygen Nanobubble First In this arm, the oxygen nanobubbles will be provided as a drink first. The oxygen nanobubbles mixture will be mixed with water and oxygenated. This will be provided as a one-time 200ml drink 10 minutes before the start of the 6 minute walk test. In this arm, the placebo will be provided as the second drink. This will be provided after atleast 2 hours after the first 6 minute walk test is completed. The placebo mixture will be mixed with water and oxygenated. This will be provided as a one-time 200ml drink 10 minutes before the start of the 6 minute walk test. |
