Abstract:
Objective:To explore the correlation between the oxygenation index and the monitored parameters of lung injury view in ventilator,so as to provide a basis for monitoring the change of oxygenation index by the parameters of lung injury view.Methods:A total of 28 patients who received mechanical ventilation treatment and admitted to respiratory department of the First Affiliated Hospital with Nanjing Medical University from May 14 to September 30,2024 were selected.The monitored parameters of lung injury views of them during mechanical ventilation treatment with invasive ventilators were collected,including platform pressure(Pplat),driving pressure(ΔP),mechanical energy(Emech),ratio of tidal volume to ideal body weight(TVe/IBW),etc..Then,the data of oxygenation index were obtained.Finally,135 valid data were screened out.The 84 pieces of data with oxygenation index≤300mmHg were included in low oxygen group,and 51 data with oxygenation index>300mmHg were included in normal group.The correlations between oxygenation index and Pplat,ΔP,Emech,TVe/IBW were conducted by pairwise analysis.Results:In the low oxygen group,the oxygenation index was[(196.302±74.522)mmHg]significantly negative correlation with Emech[(12.686±5.401)J/min](ρ=-0.425,P<0.05),but not was significant correlation with Pplat,ΔP,and TVe/IBW(P>0.05).In the normal group,there were not significant correlations between the oxygenation index and Pplat,ΔP,Emech and TVe/IBW(P>0.05).There was a significant negative correlation between Emech and rank of oxygenation index(β=-0.389,P<0.05)in the low oxygen group.Conclusion:The visualization function of the Emech of the monitored parameters in lung injury view of ventilator can provide help for monitoring the changes of oxygenation index of patients in the low oxygen group,and can improve the oxygenation of patients by optimizing mechanical energy.However,it is necessary to balance the contradiction between ventilation intensity and protection for lung.
