Trial results of a wearable multi-modal electroacoustic system have demonstrated its superior accuracy in quantifying various air flow obstructions. The results published in PubMed, revealed that the device, which employs a body area sensor network with each sensor-node having a multi-modal sensing capability, such as a digital stethoscope, electrocardiogram monitor, thermometer, and goniometer, was efficient and demonstrated a positive correlation of SNR values to the health-scale score. They researchers said that they analysed the functions in over 35 healthy subjects and 3 COPD subjects to find that the system was well-tolerated. The system gains significance as COPD exacerbations identified early can commonly be treated at home, enabling a major reduction of patient readmission and associated healthcare costs.
