Combining Bioimpedance and Myographic Signals for the Assessment of COPD During Loaded Breathing

Chronic Obstructive Pulmonary Disease (COPD) is one of the most common chronic conditions. The current assessment COPD requires a maximal maneuver during spirometry test to quantify airflow limitations patients. Other less invasive measurements such as thoracic bioimpedance and myographic signals have been studied an alternative classical methods they provide information about respiration. Particularly, strong correlations shown between respiratory volume. main objective this study investigate its combination with parameters in patients assess applicability disease monitoring. We measured bioimpedance, surface electromyography mechanomyography forty-three incremental inspiratory threshold loading protocol. introduced two novel features that can be used condition derived from variation electrical mechanical activity each cycle. These demonstrate significant differences mild severe patients, indicating lower contribution muscles global ventilation severest In conclusion, provides useful indices noninvasively breathing
