[Assessment of fluid volume in critically ill patients with extravascular lung water index].
To examine the effect of rapid infusion test guided by extravascular lung water index ( EVLWI ) on hemodynamics in critically ill patients at different states in order to guide volume resuscitation. ⋯ Rapid fluid replacement in critically ill patients with crystalloid, regardless of whether the EVLWI was normal or increased, the short-term response was affected by the volume and cardiac function of patients. Different status of patients showed different volume effect curve: no significant changes in hemodynamic parameters were found in patients with normal EVLWI and volume parameters. In patients with potential cardiac dysfunction, CI and EVLWI increased significantly; regardless of PVPI increased or normal, EVLWI and CI were increased in patients with elevated EVLWI; two different changes could be found in the two types of pulmonary edema while ITBVI was increased.

[A prospective clinical study of pleth variability index in prediction of volume responsiveness in patients with septic shock].
To evaluate the role of pleth variability index ( PVI ) by passive leg raising ( PLR ) test in volume responsiveness and volume status prediction in patients with septic shock. ⋯ PVI and SVV can better predict fluid responsiveness in mechanically ventilating patients with septic shock after PLR. PVI as a new continuous, noninvasive and functional hemodynamic parameter has the same accuracy as SVV.

Clinical Trial[The application of fibrobronchoscopy in extubation for patients suffering from acute exacerbation of chronic obstructive pulmonary disease with low cough peak expiratory flow].
To investigate the value of the application of fibrobronchoscopy in extubation for patients suffering from acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with low cough peak expiratory flow (CPEF). ⋯ The application of fibrobronchoscopy in the extubated AECOPD patients with low CPEF can reduce the rate of re-intubation, avoid the prolonged ventilation, but cannot reduce the time of ICU stay.

[Related factor of serum carnitine deficiency and influence of its deficiency on the length of hospital stay in critical ill patients].
To investigate the related factors of serum carnitine deficiency in critical ill patients, and the influence of its deficiency on the length of hospital stay. ⋯ Carnitine deficiency is significant in critically ill patients, and it is correlated with disease severity and serum TBil. The total amount of lenteral feeding was lower, and hospital stay was prolonged in critically ill patients with low serum carnitine level.

[Evaluation of tidal volume delivered by ventilators during volume-controlled ventilation].
To study the ways which ensure the delivery of enough tidal volume to patients under various conditions close to the demand of the physician. ⋯ To ensure the delivery of enough tidal volume to patients close to the demand of the physician, containable factors such as the compliance of gas piping, leakage, and gas types should be controlled.
