Ballistocardiogram signal processing: a review
2019
Health Information Science and Systems
Preserved Fulltext
An alternative approach which may help diagnose OSA and other cardiovascular diseases is the ballistocardiography. ...
In practice, BCG sensors are placed under bed mattresses for sleep tracking, and hence several factors, e.g., mattress thickness, body movements, motion artifacts, bed-partners, etc. can deteriorate the ...
Moreover, due to the high intrinsic resistance and bubble structure, the charge perseveres for a long time. ...

This is usually done by taking the fast Fourier transform or the inverse Fourier transform of the logarithm of the estimated spectrum, i.e., cepstrum of the signal using a sliding window. ...
This is because the BCG signal does not display consistent J-peaks, which can usually be the case for overnight, in-home monitoring, particularly with frail elderly. ...

Surveillance of sleeping posture is essential for bed-ridden patients or individuals at-risk of falling out of bed. ...
The system uses an infrared depth camera for data acquisition and a convolutional neural network to classify sleeping postures. ...
For example, a prolonged non-symmetrical sleeping posture might lead to structural spinal changes and symptoms [12, 13] . ...
