Abstract EN
Secretions of ventilated patients must be cleared efficiently and timely; to improve the secretion clearance efficiency of an insufflation-exsufflation device (IL-IE device) and lay a foundation for the optimization of the IL-IE device, a mathematical model of the ventilation system with the IL-IE device is set up.
Through the experimental and simulation research on the ventilation system, it can be concluded that, firstly, the mathematical model is proved to be authentic and reliable.
Secondly, with the deposition of secretion or an increase in the respiratory compliance, the peak exsufflation airflow may be reduced.
Thirdly, with a decrease in the suction pressure, the peak exsufflation airflow of the ventilated lung may rise proportionally, but the minimum pressure in the ventilated lung may descend proportionally.
To improve the efficiency of the secretion clearance but not to injure the ventilated patient, the suction pressure can be elevated properly.
Last, increasing the inspiratory positive airway pressure (IPAP) is a method to improve the secretion clearance efficiency.
This research lays a foundation for improving the secretion clearance efficiency of the IL-IE device.
