Comparing 6-Minute Walk Tests for Ambulatory Oxygen Assessment

Sponsor: Hampshire Hospitals NHS Foundation Trust

Summary

Patients with lung disease who report breathlessness on exertion are often referred for a 6MWT. Due to the nature of the 6MWT (hereon referred to as a Max-6MWT), patients are required to walk as far as they can in 6 minutes. This may lead to an inaccurate assessment of their requirement for ambulatory oxygen as this form of exercise may not correspond to their normal daily activities. In this study, patients who are routinely referred for a Max-6MWT to investigate possible exercise-induced hypoxaemia will be invited to perform an additional walking test which is performed at their normal walking speed, referred here on in as a Nor\_6MWT. We hypothesise that performing a Nor\_6MWT will provide a more accurate assessment of a patients' oxygen requirement, primarily from their oxygen desaturation during the test.

Official title: Comparison of the Standard 6-Minute Maximal Speed Walk Test Against a 6-Minute Normal Speed Walk Test as an Alternative and More Accurate Assessment for Ambulatory Oxygen Requirement.
