Issue Date: | 2021 | Publisher: | IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC | Source: | IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING, 68 (1) , p. 298 -307 | Abstract: | Chronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic conditions. The current assessment of COPD requires a maximal maneuver during a spirometry test to quantify airflow limitations of patients. Other less invasive measurements such as thoracic bioimpedance and myographic signals have been studied as an alternative to classical methods as they provide information about respiration. Particularly, strong correlations have been shown between thoracic bioimpedance and respiratory volume. The main objective of this study is to investigate bioimpedance and its combination with myographic parameters in COPD patients to assess the applicability in respiratory disease monitoring. We measured bioimpedance, surface electromyography and surface mechanomyography in forty-three COPD patients during an incremental inspiratory threshold loading protocol. We introduced two novel features that can be used to assess COPD condition derived from the variation of bioimpedance and the electrical and mechanical activity during each respiratory cycle. These features demonstrate significant differences between mild and severe patients, indicating a lower inspiratory contribution of the inspiratory muscles to global respiratory ventilation in the severest COPD patients. In conclusion, the combination of bioimpedance and myographic signals provides useful indices to noninvasively assess the breathing of COPD patients. | Notes: | Blanco-Almazan, D (corresponding author), Barcelona Inst Sci & Technol, Inst Bioengn Catalonia IBEC, Barcelona 08028, Spain.; Blanco-Almazan, D (corresponding author), Biomed Res Networking Ctr Bioengn Biomat & Nanome, Barcelona 08028, Spain. dblanco@ibecbarcelona.eu |
