Systematic review reveals ECCO2R improves respiratory mechanics in ARDS while lowering tidal volume, indicating caution due to complications.

To evaluate the efficacy of extracorporeal carbon dioxide removal in facilitating ultra-protective ventilation strategies for patients with ARDS.
Conducted a systematic search in major databases for relevant studies
Included studies with predefined criteria focusing on gas exchange and ventilator settings
Performed analyses using a random-effects model and conducted subgroup analyses.
Included 14 studies with 593 ARDS patients
ECCO2R reduced tidal volume by 1.68 mL/kg and driving pressure by 3.70 cmH2O at 24 h
Notable 28-day mortality rate was 29%
Device-related complications included bleeding (15%) and circuit clotting (19%).

Zhen et al. (2025) studied this question.
