摘要：
A body-worn sensor that measures respiratory rate and other vital signs using an acoustic sensor (e.g., a small-scale sensor). The body-worn sensor features a chest-worn patch sensor that combines both the acoustic sensor and an ECG electrode into a single adhesive patch. To measure blood pressure, the device additionally performs a ‘composite’ PTT-based measurement that features both pressure-dependent and pressure-free measurements. The acoustic sensor measures respiration rate by recording sounds related to the patients inspiration and expiration. The acoustic sensor is typically placed near the patients trachea, but can also be placed on the middle right and left side of the chest, and the middle right and left side of the back.
