Hypoxia
Conditions
Brief summary
The main purpose of this study is to learn how patients breathe on portable oxygen concentrators (POCs), and to get feedback from patients using POCs.
Detailed description
This study aims to examine patient oxygenation levels and markers of exertion (e.g. breath rate, heart rate and breath pattern) while using a portable oxygen concentrator, with the aim to understand exercise desaturation in hypoxemic subjects.
Interventions
DEVICEPortable pulsed oxygen
Hypoxemic patients will use portable pulsed oxygen at rest, and while performing a six-minute walk test.
