The high-frequency jet ventilator uses the solenoid valve and feedback techniques to control the operational parameters of the ventilator. The proposed dual-mode control mechanism allows dynamic adjustment of the tidal volume, pressure, and duration of ventilation simultaneously. The system has been verified in animal experiments and demonstrated a significant improvement in the gas exchange efficiency. Besides, the bioelectrical impedance measurement can provide real-time and accurate regional information of the lungs, which helps to monitor the patient’s condition during respiratory treatment. This work also adopts wireless communication and remote-control technology to reduce the risk of infection of medical professionals.
