摘要:
A mechanical ventilator (10) provides pressure support ventilation (PSV) to a patient (12). A power of breathing (PoB) or work of breathing (WoB) estimator (30) generates a PoB or WoB signal (34) for the patient. An error calculator (36) computes an error signal as a difference between the PoB or WoB signal and a set point PoB or WoB value (22). A controller (20) inputs a PSV control signal (24) equal to the product of the controller transfer function and the error signal to the mechanical ventilator. A patient adaptation component (52, 54, 56, 60) fits parameters of a model of a controlled mechanical ventilation system comprising the mechanical ventilator and the patient to data comprising the PoB or WoB signal and the PSV control signal generated by the operating closed loop controller, and adjusts parameters of the controller transfer function to maintain stability of the operating closed loop controller.

机械呼吸机(10)为患者(12)提供压力支持通气(PSV)。 呼吸功率(PoB)或呼吸功(WoB)估计器(30)产生患者的PoB或WoB信号(34)。 误差计算器(36)计算作为PoB或WoB信号与设定点PoB或WoB值(22)之间的差值的误差信号。 控制器(20)将等于控制器传递函数和误差信号的乘积的PSV控制信号(24)输入到机械通气机。 患者适应组件(52,54,56,60)将包括机械通气机和患者的受控机械通气系统的模型的参数拟合到包括PoB或WoB信号和由操作闭环产生的PSV控制信号的数据 控制器,并调整控制器传递函数的参数,以保持操作闭环控制器的稳定性。 p>
