Abstract: Objective To investigate the effects of different pressures sustained inflation (SI) on patients with acute res-piratory distress syndrome (ARDS) after lung recruitment of suction. Methods 40 cases of ARDS from September 2012 to January 2014 in Department of Emergency Intensive Care Unit, Chongqing Three Gorges Central Hospital were en-rolled and randomly divided into group P0, group P1, group P2, group P3, group P4, with 8 cases in each group and treated with 0, 30, 35, 40, 45 cm H2O pressure (1 cm H2O=0.098 kPa) for lung recruitment respectively. The patient's respiratory mechanics and hemodynamic index after SI lung recruitment of suction were recorded. Results ①The lung volume after lung recruitment, lung dynamic compliance (Cd) of group P1, group P2, group P3, group P4 were all high-er than those of group P0, the differences were statistically significant (P<0.05); the peak airway pressure (PIP), mean airway pressure (Pm), airway plateau pressure (Pplat) after lung recruitment of group P1, group P2, group P3, group P4 were all lower than those of group P0, the differences were statistically significant (P<0.05). There was no significant difference among group P1-P4.②The differences of mean arterial blood pressure (MAP), mean pulmonary artery pres-sure (PAP), central venous pressure (CVP) after SI between group P1, group P2, group P3, group P4 and group P0 was not statistically significant (P > 0.05). The differences of HR between group P3, group P4 and group P1, group P2, group P3 were all statistically significant (P<0.05). Conclusion 30 and 35 cm H2O are suitable pressure in the treat-ment of ARDS in patients with SI.
