Finger Wearable Device to Monitor Heart Rate Variability and Oxygen Saturation
- Conditions
- COPD
- Registration Number
- NCT03268538
- Lead Sponsor
- Chinese University of Hong Kong
- Brief Summary
Introduction: Chronic obstructive airway disease (COPD) is common condition in old age and the perception of hypoxia is often impaired in some COPD patients. Therefor it is need to monitor oxygen saturation in older people with COPD. A finger wearable device has been developed to measure oxygen saturation and heart rate variability. The investigators therefore will perform a cross sectional study to evaluate the clinical application of this finger wearable device in the detection and management of COPD in older people.
Subject and method: 100 COPD subjects and 200 community dwelling older people without diagnosis of COPD will be recruited. Physical functioning and lung function test will be performed. Subjects will wear a finger wearable device to monitor heart rate variability and oxygen saturation and wear another wrist wearable device (Actigraph) to monitor physical activity and sleep for 6 days at the same time.
Statistical analysis: Statistical analysis will be made to examine the potential association between oxygen saturation and physical activity and sleep, and the association between heart rate variability and physical activity and sleep.
