患者用人工呼吸器の呼吸回路の気道圧力を呼吸の吸息サイクル中に制御するシステム
Document Type and Number:
Japanese Patent JP3615238
Kind Code:
B2
Abstract:
The method and system for controlling airway pressure in a ventilator during the inspiratory cycle by controlling the flow of breathing gas through a flow supply valve at a desired rate of supply flow and venting the breathing gas at a desired rate of outflow through a relief valve to achieve the desired airway pressure. Measurements of the rates of actual supply flow, the actual outflow through the exhalation/relief valve, and the pressure in the airway are compared with desired values for determination the amount of error for feedback control of the ventilator system.
