Comparative Study[The effect of positive pressure ventilation combined with diaphragm pacing on respiratory mechanics in patients with respiratory failure].
To observe the effects of combining positive pressure ventilation with diaphragm pacing on respiratory mechanics in patients with respiratory failure. ⋯ Compared with positive pressure ventilation , positive pressure ventilation combined with diaphragm pacing can decrease the Paw, increase intrathoracic negative pressure, transpulmonary pressure, and Cst, and decrease WOBv, while there is no effect on Raw and R(L).

Controlled Clinical Trial[Study of the effects of mechanical ventilation on the heart function of patients with echocardiography].
To study the effects of different positive end expiratory pressure (PEEP) levels on the heart function of patients undergoing mechanical ventilation (MV) with echocardiography. ⋯ Under the same condition of MV, change in PEEP levels (0-14 cm H(2)O) do not produce any obvious effect in the normal cardiac function group, on the other hand when PEEP≥10 cm H(2)O left heart function is significantly lowered in the poor cardiac function group. Optimal PEEP may improve the cardiac function.

[Experimental study on acute respiratory distress syndrome and analysis of relevant factors in rabbits subjected to thoracic blast trauma].
To reproduce acute respiratory distress syndrome (ARDS) model in rabbit induced by chest blast injury and to analyze the pathogenesis and causes of early death in order to provide the basis for the early diagnosis of lung blast injury and its early warning system to facilitate an early treatment. ⋯ In an airtight environment, rabbit ARDS model can be reproduced successfully by blast injury with 1 917.3 mm Hg explosion pressure; TNF-α and IL-6 are involved in the pathogenesis and development of ARDS in blast injury. Pneumothorax as a result of lung rupture is the chief reason for early death and dysfunction of circulatory system is also an important reason in producing early death.
