[Study of continuous hemodynamics monitoring techniques in patients with mechanical ventilation].
To elucidate the relativity among three kinds of continuous hemodynamics monitoring techniques: thermodilution via Swan-Ganz catheter, pulse contour analysis method (PiCCO), partial CO(2) rebreathing method (non invasive cardiac output, NICO), in patients with mechanical ventilation. ⋯ PiCCO and NICO can be used as reliable measure to monitor ventilated patients bedside in intensive care unit (ICU), thus offering an assistance to optimize therapeutic strategy.

[Effect on hemodynamics during different modes of low assist ventilation].
To observe the effect on mechanical ventilation with biphasic positive airway pressure (BIPAP), pressure support ventilation (PSV) and proportional pressure support (PPS) modes on hemodynamics in patients with either normal cardiac function or impaired cardiac function in order to optimize the time to wean mechanical ventilation in patients with severe cardiac dysfunction. ⋯ In PPS mode, the effect to hemodynamics in patients with severe cardiac dysfunction is minimal, so it is suitable as a weaning mode in this groups of patients.

[Effects of different modes of artificial ventilation on lung injury in dog model of acute respiratory distress syndrome].
To investigate the effects of different modes of artificial ventilation on lung injury in a dog model of acute respiratory distress syndrome (ARDS), and to evaluate the protective effect of various parameters in mechanical ventilation on lung injury. ⋯ Large tidal volumes with high inspiratory flow and high respiratory rate may cause severe ventilator induced lung injury (VILI). Reduction of inspiratory flow and respiratory rate with large tidal volume ventilation may provide pulmonary protection.

[Clinical study of the setting of positive end expiratory pressure in patients with acute cardiogenic pulmonary edema during mechanical ventilation].
To compare the effects on hemodynamics and lung mechanics when different positive end expiratory pressure (PEEP) levels were used in acute cardiac pulmonary edema. ⋯ The mode of artificial ventilation should be adjusted according to the changes in hemodynamics and lung mechanics. PEEP should be individualized, and 5-7 cm H(2)O (normally below 10 cm H(2)O) is suitable.

[Clinical study of mechanical ventilation in acute cardiogenic pulmonary edema patients].
To study the application of mechanical ventilation in acute cardiogenic pulmonary edema (ACPE), and compare the changes in hemodynamics between continuous positive airway pressure proportional pressure support (CPAP-PPS) with continuous positive airway pressure-pressure support ventilation (CPAP-PSV). ⋯ Hemodynamic monitoring should be performed when medicinal intervention and non-invasive/invasive ventilation are given to ACPE patients. Pressure controlled ventilation is recommended, and PEEP should be individualized (normally 6-15 cm H(2)O). Spontaneous ventilation should be restored as soon as possible, CPAP-PPS mode is practicable in patients in whom weaning of mechanical ventilation is difficult.
