Intensive Care Medicine Experimental

Intensive Care Medicine Experimental (ICMx) is an open access journal dedicated to translational research that bridges basic science and clinical practice in critical care and emergency medicine. The journal focuses on physiology and pathophysiology relevant to critical illness, aiming to bring novel diagnostics and therapies closer to the bedside. It seeks work that advances understanding of critical illness mechanisms, informs and supports clinical trial design, tests innovative interventions, and develops or refines experimental models pertinent to intensive care. ICMx welcomes original studies, reviews, hypothesis papers, and state‑of‑the‑art methodology papers, and serves researchers working to improve emergency care for critically ill patients. It is the official journal of the European Society of Intensive Care Medicine (ESICM).
