assist-control模式可以定容(volume-targeted),也可以定压(pressure-targeted,也称为压力控制通气,pressure control ventilation,PCV)。在定容模式下,呼吸机每次输送的均为指令(mandatory)通气,吸气相的通气参数,如潮气量或气道压力,以及吸气向呼气...
Marini JJ. Point: is pressure assist-control preferred over volume assist-control mode for lung protective ventilation in patients with ARDS? Yes. Chest 2011; 140: 286-290.MacIntyre N: Counterpoint: Is pressure assist-control preferred over volume assist-control mode for lung protective ventilation...
The aim of this study was to compare the effect of a pressure-controlled strategy allowing non-synchronised unassisted spontaneous ventilation (PC-SV) to a conventional volume assist-control strategy (ACV) on the outcome of patients with acute respiratory distress syndrome (ARDS). Methods Open-label...
A control system for an inflatable chamber operably positionable with respect to an aorta of a patient monitors an actual flow duration time for inflating and/or deflating the inflatable chamber with a predetermined volume of pressurized fluid and compares the actual flow duration time to a target...
SIMV with pressure support also produced a significantly greater minute volume and ventilatory equivalent than assist-control. There were no significant differences between assist-control and SIMV. All three modes produced a lower ventilatory equivalent and higher oxygen consumption than spontaneous breathing...
E.压力支持通气(pressuresupportventilation,PSV) 点击查看答案 第9题 对“辅助控制(A/C)”通气,描述正确的是() A.在辅助控制通气中,呼吸可由患者触发 B.在辅助控制通气中,分钟通气量和频率均由操作者控制,因此MV和f的监测值与设定值完全相等 C.由于触发的原因,在辅助控制通气中,呼吸频率可能大于设置值 D....
Proportional assist ventilation (PAV) and neurally adjusted ventilatory assist (NAVA) were both developed to improve patient-ventilator synchrony by proportionally unloading ventilatory effort and turning control of the ventilatory pattern over to the patient. This paper discusses PAV's and NAVA's ...
Many lower-limb exoskeletons have been developed to assist gait, exhibiting a large range of control methods. The goal of this paper is to review and classify these control strategies, that determine how these devices interact with the user. In addition
PROBLEM TO BE SOLVED: To provide a support control device for efficiently promoting sales by giving a notification prompting replacement at an appropriate time and in an appropriate form in a house where a fuel cell cogeneration system is introduced. SOLUTION: In a fuel cell unit of a cogenerati...
The purpose of this study is to develop a suitable control method for the UPVAD. The UPVAD inflow cannula equipped with an implantable pressure sensor was inserted into the ventricle. Therefore, pressure variation that synchronized with the natural heartbeat and negative pressure spike caused the ...
