1．独有的成熟通气模式：压力调节容量控制（PRVC）；容量支持（VS）；压力调节容量控制的同步间歇指令通气（SIMV(PRVC)+PS）；自动模式（Automode）；双水平气道正压（Bi-Vent）。2．

独有的资料存储卡，可以很容易地存储病人的资料（包括所有的呼吸监测参数），便于日后在个人电脑中进行分析和研究。3．

独有的开放肺工具（OpenLungTool）,帮助医生非常方便地找到病人肺真正的打开点和闭合点，并且使病人的肺得到了很好的锻炼。07.05.2026Servo…Technicaltraining44．

独有的超声流量传感器，故障率低，使呼出气道更为通畅（可以帮助患者呼吸功最小化），提供了更快的反应速度（采样频率：2000次/秒），避免人机对抗，使人机更好地协调起来。5．

独有的呼吸监测参数：浅快呼吸指数（SBI）、时间常数（Tc）、病人的呼吸功（WOBp）、呼吸机的呼吸功（WOBv）、呼吸末二氧化碳（etCO2）、总PEEP、病人的自主吸气时间与总时间比（Ti/T）、自主呼出分钟通气量（Mvesp/）。6．

独有的呼吸波形和数据20秒存储，方便快捷。
