Abstract:

An airway pressure and flow data acquisition system is developed to investigate the approach to building the bi-level positive airway pressure(BiPAP)in a ventilator. A number of experiments under different breathing situations and states are conducted and the experimental data are recorded. According to the data from these experiments, the variation characteristics of the pressure and flow are analyzed using Matlab. The data analysis results show that the pressure increases while the flow decreases in the expiratory phase; contrarily, the pressure decreases while the flow increases in the inspiratory phase; during the apnea state, both the pressure and the flow remain unchanged. According to the above variation characteristics of breath, a feedback-based method for creating bi-level positive airway pressure is proposed. Experiments are implemented to verify the BiPAP model. Results demonstrate that the proposed method works effectively in following respiration and caters well to most polypnea and apnea events.
