正反馈在流量调节持续气道正压通气模式的应用

Positive Feedback Using in FRCPAP

本文介绍了呼吸机流量调节持续气道正压通气模式(FRCPAP),它是在持续气道正压通气模式(CPAP)基础上加以改进的。此模式采用两个反馈环,流量正反馈实现流量控制,进一步加快了对病人需求的响应,压力负反馈实现压力控制,进一步建立系统的稳定性,达到在控制压力的同时对流量进行调节的效果,使得呼吸机系统的输出阻抗进一步减少,从而减小了病人的呼吸肌强迫作功,提高了病人的舒适度。

Describes a ventilator model called Flow Regulated Continuous Positive Airway Pressure （FRCPAP）, which is improved based on Continuous Positive Airway Pressure （CPAP）. FRCPAP simultaneity controls the pressure and regulates the flow. The method establishes a near zero output impedance in the ventilator system and results in the lower imposed work of breathing.
