Comparison of lung compliance indicators at different time points between the two groups

Time	PaO2			OI			CL
	F	DF		F	DF		F	DF
F: Pulmonary protective ventilation strategy group; DF: Dexmedetomidine combined with a pulmonary protective ventilation strategy group; MDA: Malondialdehyde; PaO2: Arterial oxygenation pressure; OI: Oxygenation index; CL: Lung compliance. *P < 0.05 vs F group.
