What does breathing artifact in the lungs mean?
In conclusion, respiratory artifact is commonly seen in routine 12-lead ECGs of hospitalized patients. It is associated with a high-risk state of increased work of breathing due to either compromised cardiac or pulmonary function.
How do I get rid of motion artifacts?
Independent component analysis (ICA) is a common method [6], which can separate motion artifacts and clean PPG signal from multi-channel corrupted PPG signals. However, if the statistical independence between motion artifacts and clean PPG signals is not well satisfied, the method could hardly be effective [7].
