Relationship between Driving Pressure and Mortality in Ventilated Patients with Heart Failure: A Cohort Study

Table 3

Threshold effect analysis of driving pressure on in-hospital mortality.

Threshold of driving pressure	OR	95% CI	P value
<14.27 cmH2O	0.89	0.75–1.05	0.176
≥14.27 cmH2O	1.17	1.07–1.30	<0.001

Adjustment factors included age, sex, BMI, heart rate, MAP, WBC, hemoglobin, creatinine, CVP, NT-proBNP, PEEP, PH, PaO₂, PaCO₂, PF ratio, ventilation mode (CMV), VT/PBW, Elixhauser score, SOFA score, and SAPS score.
