Abstract Objective：To investigate the differences of patients’comfort who were treated with neurally adjusted ventilatory assist（ NAVA） or pressure support ventilation（ PSV）.Method：Sixty patients treated with mechanical ventilation were randomly divided into two groups.NAVA group and PSV group，and each group consist of 30 cases.Mechanical ventilation continued more than 24 hours，The Impact Mechanical Ventilation Patients Comfortable Situation Questionnaire was used to investigate.Adopted analgesia in patients with two patterns composed more than 24 hours（ choose the same analgesic sedative drugs and the same dose），used Riker sedation - agitation scale（ SAS） method for retrospective investigation and analyzed，compared two groups of patients comfortable situation.Result：In patients with NAVA group with PSV endotracheal intubation，sputum suction，dry mouth，thirst，and restricted movement no statistical difference，NAVA group lower incidence of manmachine against PSV（P<0.05）.After sedation analgesia in patients with two groups of NAVA SAS score was lower than PSV group（ P<0.05）.Conclusion：NAVA mode compared with PSV pattern，reduces the patient discomfort，due to the manmachine confrontation in patients of agitation can alleviate NAVA mode.The result shows that the implementation of NAVA mode may be the cause of improving patient comfort.
