Abstract:
Objective To investigate the advantages of the Siaretron 1000 ventilator at high pressure and the range of tidal volume for reference through the comparison of simulated actual respiratory tidal volumes between the Siaretron 1000 and Nuffield 200 type ventilators at different ambient pressures.Methods Tidal volumes were measured with 2 different ventilators at pressures of 0.1,0.18,0.24,0.28 and 0.6 MPa (absolute pressure).The tidal volumes of Siaretron 1000 ventilator were set at 300,500 and 800 ml and inspiratory time ratios were set at 33％,40％ and 50％.Respiratory ratios of Nuffield 200 ventilator were set at 1∶ 2,tidal volume at 500 ml.Then,changes in tidal volumes,respiratory rates and peak airway pressures were measured respectively.Results The tidal volumes determined with Siaretron 1000 ventilator tended to decline with the increase of environmental pressures,with statistical significance (P ＜ 0.05).Changes in tidal volumes at pressures of lower than 0.28 MPa were less than 20％,while changes in tidal volumes measured with Nuffield 200 ventilator at pressures of higher than 0.18 MPa were greater than 20％.Conclusions With the increase in ambient pressure,actual tidal volume measured with Siaretron 1000 ventilator tended to decline,which could meet the demands of mechanical ventilation to a certain extent.
