Abstract:
|
The study of the mechanomyographic signal of
the diaphragm muscle (MMGdi) is a promising technique in
order to evaluate the respiratory muscles effort. The
relationship between amplitude and frequency parameters of
this signal with the respiratory effort performed during
respiration is of great interest for researchers and physicians
due to its diagnostic potentials. However, MMGdi signals are
frequently contaminated by a cardiac vibration or
mechanocardiographic (MCG) signal. An adaptive noise
cancellation (ANC) can be used to reduce the MCG
interference in the recorded MMGdi activity. In this paper, it is
evaluated the proposed ANC scheme by means of a synthetic
MMGdi signal with a controlled MCG interference. The
Pearson’s correlation coefficient (PCC) between both root
mean square (RMS) and mean frequency (fm) of the synthetic
MMGdi signal are considerably reduced with the presence of
cardiac vibration noise (from 0.95 to 0.87, and from 0.97 to
0.76, respectively). With the ANC algorithm proposed the effect
of the MCG noise on the amplitude and frequency of MMG
parameters is reduced considerably (PCC of 0.93 and 0.97 for
the RMS and fm, respectively). The ANC method proposed in
this work is an interesting technique to attenuate the cardiac
interference in respiratory MMG signals. Further investigation
should be carried out to evaluate the performance of the ANC
algorithm in real MMGdi signals. |
