The effect of the adaptive support ventilation in respiratory failure

Objective:To investigate the clinical value of the adaptive support ventilation(ASV) in patients with respiratory failure. Methods:58 cases with respiratory failure needed mechanical ventilation were randomly divided into two groups,the observation group(ASV) for 29 cases,29 cases of the control group between synchronized mandatory ventilation exhaust ventilation + pressure support(SIMV + PSV) ,two groups at the same time mechanical ventilation until weaning,compared records of the two modes of respiratory mechanics and hemodynamic parameters,blood gas analysis,comfort,ventilation time and the success rate of weaning. Results:All patients were successfully offline,significantly reduced respiratory frequency,tidal volume(VT) increased significantly(P0.05) ,peak airway pressure(Ppeak) and inspiratory resistance(R) decreased significantly(P0.05) ,intravenous compliance(Cstat) gradually increased(P0.05) . ASV machine ventilation on patients with significantly shortened(P0.05) . Conclusion:ASV under conditions of respiratory mechanics in patients with auto-adjust at the level of inspiratory pressure support and enhance tidal volume,reducing respiratory rate,and on hemodynamics and do not affect vital signs,and can shorten the time the machine,it is obviously superior to conventional ventilation,and easy to operate and is worth to promote the clinical application.
