In this interventional clinical trial, researchers will administer electroacupuncture versus sham electroacupuncture to sepsis patients with ARDS and collect objective outcome measures. The study will be divided into 2 groups. The EA group will receive electroacupuncture and the SHAM-EA group will receive sham electroacupuncture. The purpose of this study is to investigate the effect of electroacupuncture on the synthesis of SPMs in sepsis patients with ARDS.
