VCV：潮气量（VT）、呼吸频率（RR）、吸呼比（I/E）和吸气流速完全由呼吸机来控制。辅助/控制通气(A/C)辅助/控制通气(A/C)：病人有自主呼吸时，机器随呼吸启动，一旦自发呼吸在一定时间内不发生时，机械通气自动由辅助转为控制型通气。它属于间歇正压通气。A/CMode 同步间歇指令通气（SIMV）同步间歇指令通气（...
Patients and Methods: This prospective, single blinded study included 60 patients who assigned randomly into two equal groups: group A: patients on volume-controlled ventilation mode VCV and group B: patients on pressure-controlled ventilation mode PCV. Results: Baseline c...
As an answer to these risks, PCV mode, which delivers tidal volume using preset pressure and inspiratory time at a decelerating flow, became an alternative to VCV. While PCV does work to attain tidal volume at lower peak inspiratory pressures, this benefit is achieved at an ...

1)机组正在减负荷的过程中运行人员手动解除AGC至本地控制时,AGC指令为652MW而机组实发功率为660MW,解至本地控制后由于目标负荷跟踪的是AGC指令,所以在切换后机组目标负荷变为652MW,同时解除AGC的信号(REMOTE_MODE)触发目标负荷跟踪切换信号(TRACK_LDC)发1s的的脉冲,导致机组目标负荷指令未经过机组负荷变化率及机组负...
