The system pressure relief valve of the Dräger AV-E anesthesia ventilator is powered by connecting tubing from the ventilator. In this case, the tubing became kinked when the anesthesia machine was moved. This resulted in an iatrogenically induced valve malfunction and increasing minimum and peak pressures in the patient circuit. A laboratory study was performed to evaluate the effects of kinking the connecting tubing. The potential for producing barotrauma or hypoventilation with this design of ventilator is discussed. Repositioning the anesthesia machine after a satisfactory check may precipitate a hazardous situation. An anesthesia machine should be checked out in the final position in which it is to be used.
德尔格AV-E麻醉呼吸机的系统泄压阀由来自呼吸机的连接管道提供动力。在这种情况下，麻醉机移动时管道发生了扭结。这导致了医源性阀门故障，并使患者回路中的最小和峰值压力增加。进行了一项实验室研究，以评估连接管道扭结的影响。讨论了这种呼吸机设计产生气压伤或通气不足的可能性。在检查满意后重新放置麻醉机可能会引发危险情况。麻醉机应在其使用的最终位置进行检查。
