Background:
Management of driving pressure(ΔP) may contribute to improvement of survival rate of acute respiratory distress syndrome (ARDS). The purpose of this study was to develop a database of ARDS, to analyze the relation of the ΔP and the mortality rate.
Method:
We retrospectively identified 32 patients, who sustained from ARDS, using the ventilator data from January 1, 2016 to June 30, 2018. The comparison criteria for ΔP of ARDS were ΔP≦14 cmH2O : low pressure group, ΔP≧15 cmH2O: high pressure group. The secondary end-point was 28-day. Data are presented as percentages and numbers, or median and IQR. The chi-square test was performed to compare proportions in the different groups. The p-value < 0.05 was considered statistically significant.
Result:
Among 1845 patients, who were admitted to ICUs, 32 (1.7%) patients were presented as the inclusion criteria for ventilator in ARDS. The median [IQR] of age in low pressure group ranged from 71[58-79] years and 54% was male. Although there was no significant difference in the chi-square test, the low pressure group contributed to the survival rate.
Conclusion:
Low pressure of ΔP contributed to the improvement of survival rate in the ARDS. The present study provides information about the current status of ventilator for ARDS. Further studies are needed to investigate the effects of ARDS based on ΔP.
