研究目的:

验证V/Q不匹配能否作为ARDS严重程度及预后的实时、综合指标,并比较EIT搏动法和高渗盐水注射法的一致性。  

Objectives of Study:

To verify whether V/Q mismatch can serve as a real-time, comprehensive indicator of ARDS severity and prognosis, and to compare the consistency between the EIT pulsatile method and the hypertonic saline bolus method.
