Combining inductive plethysmography with ECG-derived respiration in a wearable bioshirt improves the reliability of respiratory rate monitoring against motion artifacts.
May aid ambulatory respiratory monitoring; leaves open prospective clinical validation.
AIn this study, we developed a wearable physiological measurement device (bioshirt). The developed bioshirt can record ECG (lead I, lead II, V1), blood oxygen saturation, 2-axis acceleration, and skin temperature in mobile environment. Sensors are embedded into the bioshirt. It showed noticeable performance in terms of usability and monitoring. Respiration signal is acquired by inductive plethysmograph (IP). However, acquired IP signal is by the upper body movement like arm or abdomen movement. To get correct respiratory signal, we use both IP and EDR (ECG-derived respiration). EDR is used to supplement the IP that is contaminated by some artifact. As result, it provide suitable respiration rate (RR) although IP is contaminated by some noise.

Nam et al. (2005) studied this question. Wearable physiological measurement device (bioshirt) using IP and EDR was evaluated on Respiration rate (RR).
