Outcomes of Venopulmonary Extracorporeal Membrane Oxygenation Conversion in Patients With Severe Respiratory Failure on Venovenous Support.
Article in ASAIO journal (American Society for Artificial Internal Organs : 1992), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Severe respiratory failure is frequently complicated by right ventricular dysfunction (RVD), which occurs in 20-50% of cases. In patients on venovenous extracorporeal membrane oxygenation (VV ECMO) with refractory RVD, conversion to venopulmonary (VP) ECMO can provide additional mechanical support. This study evaluates the impact of VV to VP ECMO conversion on mortality and end-organ dysfunction in severe respiratory failure. A retrospective cohort study of 19 adult patients on VV ECMO who were converted to VP ECMO was performed. Outcomes included in-hospital mortality, resolution of acute kidney injury (AKI), pressor requirements, ventilator and ECMO parameters, and ECMO support duration. Venopulmonary ECMO conversion facilitated AKI resolution in 62.5% of patients with pre-conversion AKI (5/8) and was associated with liberation from continuous renal replacement therapy in 40% of patients (2/5). Conversion resulted in reduced pressor requirements (7/9, 78%), ECMO flows (15/19, 79%), sweep gas flow (12/19, 63%), ECMO fraction of inspired oxygen (FiO2; 5/19, 26%), and ventilator FiO2 (3/19, 16%). Venopulmonary ECMO conversion facilitated sedation weaning in 10 patients (53%) which was previously not tolerated due to desaturation events on VV ECMO. Overall, VP ECMO conversion was associated with improved oxygenation, hemodynamic stability, and end-organ function in the majority of patients.
