contactless monitoring of breathing patterns and respiratory rate at the pit of the neck a single camera approach
Journal of Sensors, 2018Co-Authors: Carlo Massaroni, Daniela Lo Presti, Emiliano Schena, Daniel Simoes Lopes, Sergio SilvestriAbstract:Vital signs monitoring is pivotal not only in clinical settings but also in home environments. Remote monitoring devices, systems, and services are emerging as tracking vital signs must be performed on a daily basis. Different types of sensors can be used to monitor breathing patterns and respiratory rate. However, the latter remains the least measured vital sign in several scenarios due to the intrusiveness of most adopted sensors. In this paper, we propose an inexpensive, off-the-shelf, and contactless measuring system for respiration signals taking as region of interest the pit of the neck. The system analyses video recorded by a single RGB camera and extracts the respiratory pattern from intensity variations of reflected light at the level of the collar bones and above the sternum. Breath-by-breath respiratory rate is then estimated from the processed breathing pattern. In addition, the effect of image resolution on monitoring breathing patterns and respiratory rate has been investigated. The proposed system was tested on twelve healthy volunteers (males and females) during quiet breathing at different sensor resolution (i.e., HD 720, PAL, WVGA, VGA, SVGA, and NTSC). Signals collected with the proposed system have been compared against a Reference signal in both the frequency domain and time domain. By using the HD 720 resolution, frequency domain analysis showed perfect agreement between average breathing frequency values gathered by the proposed measuring system and Reference Instrument. An average mean absolute error (MAE) of 0.55 breaths/min was assessed in breath-by-breath monitoring in the time domain, while Bland-Altman showed a bias of −0.03 ± 1.78 breaths/min. Even in the case of lower camera resolution setting (i.e., NTSC), the system demonstrated good performances (MAE of 1.53 breaths/min, bias of −0.06 ± 2.08 breaths/min) for contactless monitoring of both breathing pattern and breath-by-breath respiratory rate over time.

Smart textile for respiratory monitoring and thoraco-abdominal motion pattern evaluation
Journal of Biophotonics, 2018Co-Authors: Carlo Massaroni, Cecilia Venanzi, Amanda P. Silvatti, Daniela Lo Presti, Michele Arturo Caponero, Francesco Giurazza, Paola Saccomandi, Domenico Formica, Emiliano SchenaAbstract:The use of wearable systems for monitoring vital parameters has gained wide popularity in several medical fields. The focus of the present study is the experimental assessment of a smart textile based on 12 fiber Bragg grating sensors for breathing monitoring and thoraco-abdominal motion pattern analysis. The feasibility of the smart textile for monitoring several temporal respiratory parameters (ie, breath-by-breath respiratory period, breathing frequency, duration of inspiratory and expiratory phases), volume variations of the whole chest wall and of its compartments is performed on 8 healthy male volunteers. Values gathered by the textile are compared to the data obtained by a motion analysis system, used as the Reference Instrument. Good agreement between the 2 systems on both respiratory period (bias of 0.01 seconds), breathing frequency (bias of -0.02 breaths/min) and tidal volume (bias of 0.09 L) values is demonstrated. Smart textile shows good performance in the monitoring of thoraco-abdominal pattern and its variation, as well.

MeMeA - Smart textile based on FBG sensors for breath-by-breath respiratory monitoring: tests on women
2018 IEEE International Symposium on Medical Measurements and Applications (MeMeA), 2018Co-Authors: Daniela Lo Presti, Paola Saccomandi Emiliano Schena, Michele Arturo Caponero, Carlo Massaroni, Domenico Formica, G Di TomasoAbstract:The use of wearable systems for monitoring vital parameters has gained wide popularity in several medical fields, especially in the respiratory monitoring. The focus of the present study is the experimental assessment of a male-fit smart textile based on twelve fiber Bragg grating sensors for the monitoring of respiratory parameters on eight female volunteers. In particular, breath-by-breath temporal respiratory parameters (i.e., respiratory period, breathing frequency, duration of inspiratory and expiratory phases), and breath-by-breath volume variations (i.e., tidal volume measurements) have been estimated by the sensor’s outputs of the t-shirt. Results show good agreement between measurements carried out by the smart textile and the Reference Instrument (i.e., motion capture system with passive markers), with a bias of 0.002 s for the respiratory period and of 0.014 breaths·$\mathbf{min}^{\mathbf {-1}}$ for breathing frequency. However, bias found in the comparison of breath-bybreath tidal volumes discourages the use of the present smart textile for volume monitoring in female population. The promising results promote further development of the system to allow continuous monitoring in clinical setting and for tele-monitoring purposes.
