Hardware-software complex for studying of breathing volume parameters

In this paper, a developed hardware-software complex for studying volume parameters of breathing is considered. To estimate the volumetric parameters of breathing, a method for registering the movement of the chest and abdominal walls by changing the overall dimensions of the chest and abdomen with ranking according to the anatomical features of a person is proposed. A technique for researching the volumetric parameters of breathing based on the method of video recording of the movements of the chest and abdominal wall of a person was developed. The proposed method was used to estimate volume parameters of breathing among men aged 20–22 years. BMI (body mass index) ranged from 18.2 to 30.1 kg/m². The research of volumetric parameters of respiration was carried out using the hardware-software complex and the proposed technique for registering the biomechanics of breathing. Conclusions about the relation between volumetric parameters of breathing and the values of changes in the overall dimensions of the chest and abdomen during respiration were drawn. A correlation-regression analysis of the volumes of inhaled/exhaled air and the values of deviations of the overall dimensions of the chest and abdomen was carried out. The results obtained indicate a strong relation between volumetric parameters of breathing and the values of deviations in the overall dimensions of the chest and abdomen.
