Abstract
Objective:To observe the effect of adaptive support ventilation(ASV) on respiratory mechanics and arterial blood gas in elderly patients with respiratory failure.Method:A total of 77 elderly patients with respiratory failure treated by mechanical ventilation in our hospital were selected.According to different mechanical ventilation treatments,they were divided into control group(n=37) and observation group(n=40). The control group was treated with simultaneous intermittent mandatory ventilation(SIMV)+pressure support ventilation(PSV) mechanical ventilation,while the observation group was treated with ASV mechanical ventilation.The success rate of ventilator withdrawal,total time of mechanical ventilation,respiratory mechanics and arterial blood gas related indexes during mechanical ventilationbetweentwo groups were compared.Result:The success rate of ventilator removal in observation group and control group was 82.5%(33/40) and 81.1%(30/37) respectively,the difference was not statistically significant(P>0.05).The total time of mechanical ventilation inobservation group(12.5±3.1) d was significantly less than(15.7±3.5) d of control group,the difference was statistically significant(P<0.05).Theventilation volume per minute(MV) between two groups was compared, the difference was not statistically significant(P>0.05).The respiratory rate(f),airway peak pressure(Ppeak), mean airway pressure(Pmean),plateau airway pressure(Pplat),inspiratory resistance(Rinsp),and expiratory resistance(Rexp) in observation group were significantly lower than those of control group,and tidal volume(VT) was significantly higher than that of control group(P<0.05).The arterial blood gas indexes between two groups during mechanical ventilation treatment was compared,the difference was not statistically significant (P>0.05).Conclusion:ASV model can not only improve the respiratory mechanics of elderly patients with respiratory failure related indicators,but also has high safety,worthy of clinical application.关键词
