Eligibility
Inclusion criteria
Inclusion criteria: 1. Chronic breathlessness; due to chronic non-malignant lung disease such as Chronic Obstructive Pulmonary Disease,(COPD), any Interstitial Lung Disease (ILD), or other respiratory diseases 2. Modified Medical Research Council (mMRC) breathlessness 3 or 4 3. Able to provide informed written – or witnessed verbal - consent, complete study exercise tests and outcome measures 4. Patients may have current or prior, or no, fan use experience 5. Adults, no upper age limit
Exclusion criteria
Exclusion criteria: 1. Unable to provide informed consent 2. Unable to complete study measures 3. Unable to perform the sit to stands tests due to musculoskeletal problems, or currently advised by a usual care clinician to avoid such physical activity for any other reason 4. Unable to tolerate fan or trigeminal nerve damage 5. Patients using ambulatory oxygen for confirmed exercise-related oxygen desaturation, or long-term oxygen therapy
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Breathlessness measured using the 0 to 10 Numerical Rating scale (NRS) at baseline, at maximal breathlessness after the sit to stand test and every 1 minute during the first 10 minutes of recovery from maximal breathlessness or until return to baseline breathlessness level, whichever occurs first | — |
Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures as of 18/03/2022: 1. Heart rate measured using a pulse-oximeter at baseline, at maximal breathlessness after the sit to stand test and every 30 seconds during the first 10 minutes of recovery from maximal breathlessness 2. Oxygen saturation measured using a pulse-oximeter at baseline, at maximal breathlessness after the sit to stand test and every 30 seconds during the first 10 minutes of recovery from maximal breathlessness 3. A thermal image of the temperature of the participant’s cheek trigeminal nerve area, recorded with a thermal camera at baseline, at maximal exertion and after 3 and 5 minutes recovery time from the sit to stand test [These measures are recorded during recovery after each of the five sit to stand tests (four with different airflow rates and one with no airflow - control)] 4. The pleasantness of the airflow speeds from the fan measured using the 0 to 10 Numerical Rating scale (NRS) after completion of all the tests 5. The number of sit to stands completed in 1 minute recorded for each of the five sit to stand tests 6. The participant preferred airflow rate from the fan on completion of all the tests 7. The participant's preferred fan from 3 different models recorded on completion of all the tests _____ Previous secondary outcome measures: 1. Heart rate measured using a pulse-oximeter at baseline, at maximal breathlessness after the sit to stand test and every 30 seconds during the first 10 minutes of recovery from maximal breathlessness 2. Oxygen saturation measured using a pulse-oximeter at baseline, at maximal breathlessness after the sit to stand test and every 30 seconds during the first 10 minutes of recovery from maximal breathlessness 3.
