인공호흡기용 PEEP 밸브의 압력공압제어에 관한 연구

다국어 초록 (Multilingual Abstract)

??Patients in respiratory distress may be put on machines(ventilators) that fully or partly breathe for them. In the pressure control mode of mechanical ventilation system, not only inspiration but also expiration pressure should be maintained for a given locus, in order to increase the oxygen transfer rate within the breathing cycle. Conventional system uses solenoid valves are adapted for mixing the inspiration gases(air, O₂ and N₂) with on/off mode. Furthermore, the peep valve which is actuated by voice coil, controls the inspiration and expiration pressure with PID control algorithm. The experimental results show that the ventilation pressure which is measured at the expiration path way follows the various types of command signal exactly within the normal breathing pressure ranges that the proposed ventilation circuit and control algorithm have an excellent performances for the mechanical ventilation system.
