Randomized Controlled Trial Comparative Study[An auto control comparison of the use of ProSeal laryngeal mask airway and standard laryngeal mask airway for positive pressure ventilation].
To compare the ProSeal laryngeal mask airway (PLMA) and the standard laryngeal mask airway (SLMA) for intermittent positive pressure ventilation (IPPV) in a randomized auto control design. ⋯ Compared with SLMA, PLMA can achieve a higher airway seal pressure and potentially isolate the glottis and the upper esophagus, and is safer and more effective for positive pressure ventilation.

[Effect of posture and positive end expiratory pressure on central venous pressure in patients with mechanical ventilation].
To investigate the effect of posture and different positive end expiratory pressure (PEEP) on central venous pressure (CVP) in critically ill patients with mechanical ventilation (MV). ⋯ CVP was not influenced by the posture. CVP increased gradually with the increase in PEEP. Changing posture and weaning of mechanical ventilation led to deterioration of oxygenation and increased agitation. Maintaining of posture and PEEP when measuring CVP could improve safety and comfort of patients, and reduce the work of nursing.

[Analysis of risk factors in prognosis in patients requiring long-term mechanical ventilation].
To analyze risk factors in patients receiving mechanical ventilation in intensive care unit (ICU). ⋯ The time of tracheostomy, the levels of HCT value, the amount of PLT were independent risk factors associated with patients requiring LTMV.

[Application of the bispectral index monitor in mechanical ventilation in patients under sedation in the intensive care unit].
To evaluate bispectral index (BIS) technology in post-operative patients under sedation undergoing mechanical ventilation according to Ramsay sedation scales in intensive care unit (ICU). ⋯ BIS measurements evaluated in clinically relevant ranges compare favorably with Ramsay scale. BIS may be best used to identify and prevent over or under sedation of mechanical ventilated patients in the ICU.

[Effects of mechanical ventilation on the expression of Toll like receptor 4 in rat's alveolar macrophages].
To investigate the effects of mechanical ventilation on Toll like receptor 4 (TLR4) in rat's alveolar macrophages (AM). ⋯ Large V(T) mechanical ventilation induced injury of lungs and up-regulated TLR4 expression in rat's AM. Small V(T) mechanical ventilation avoided above-mentioned changes.
