Abstract:
Respiratory belt is a full-service home medical equipment to monitor respiration for homecare. Respiratory belt indicates breathing strength and characterizes breathing patterns. This paper describes a noninvasive respiratory movement monitoring using Magnetic Resonance Imaging (MRI) and respiratory belt simultaneously to investigate internal-external correlation. Twenty healthy subjects participated in this study and they all performed paced breathing (12 cycles/minute) during experiment. The diaphragmatic movement area and the anterior-posterior (AP) diameter of the body contour represented as indexes of internal respiratory movement and the respiratory belt signal represented as external index. Cross correlation was used to evaluate the similarity between internal and external respiratory movement. The results indicated that diaphragmatic movement area versus respiratory belt signal performed strong negative correlation (R value is -0.847±0.06). The AP diameter of the body contour versus respiratory belt performed strong positive correlation (R value is 0.837±0.09). In conclusion, respiratory belt correlates strongly with diaphragmatic movement area and AP diameter of the body contour. Therefore, respiratory belt is a reliable external respiratory monitoring technique to detect respiratory movement in homecare.
