ABSTRACT
Objective To study the influence of the different tidal volume on hemodynamics,pulmonary ventilation and pulmonary mechanics during mechanical ventilation in patients with acute lung injury.Methods To adopt contrast method,making use of the VIIP +0.196 kPa of P-V curve to decide PEEP,then according to the VUIP of P-V curve,obtaining the three different data of humidity 100%Vt,85% Vt and 70 Vt.At the same time,monitoring the change of static compliance,the changing of hemodynamics and P-V curve.Results 85%Vt group was better than 100%Vt group and 70%Vt group in the heart rates,CVP,PaO_2,the peak airway pressure(PIP) and mean pressure(Pm),Cst,PaO_2/FiO_2.Conclusions When insuring the PEEP data in low inflection point pressure (Pinf) of breathing system P-V curve,and 85% humidity in upper inflection point pressure,which is in accordance with individual protecting breathing strategy.The curative effect is the best for improving static compliance and decreasing the harm of lung injury.The change of pressure-volume curve should be paid attention to in nursing.
