Early detection of heart failure in older adults will be a significant issue for the foreseeable future. The current article presents a case study to describe how monitoring ballistocardiogram (BCG) waveforms captured non-invasively using sensors placed under a bed mattress can detect early heart failure changes. Heart and respiratory rates obtained from the bed sensor of a female older adult who was hospitalized with acute mixed congestive heart failure, clinic notes, and data from computer simulations reflecting increasing diastolic dysfunction were analyzed. Mean heart and respiratory rate trends obtained from her bed sensor in the prior 2 months did not indicate heart failure. BCG waveforms resulting from the simulations demonstrated changes associated with decreasing cardiac output as diastolic function worsened. Developing new methods for clinically interpreting BCG waveforms presents a significant opportunity for improving early heart failure detection. [Journal of Gerontological Nursing, 46(7), 41-46.].

Despins et al. (2020) conducted a case report in Heart Failure (n=1). Non-invasive hydraulic bed sensor monitoring (ballistocardiogram waveforms) vs. Unmonitored baseline or traditional clinical monitoring was evaluated on Detection of early heart failure changes via sensor signals. Non-invasive monitoring of ballistocardiogram waveforms via bed sensors demonstrated physiological changes associated with decreasing cardiac output as diastolic function worsened, highlighting a method for early heart failure detection.
