Thoracic electrical impedance tomography from technological promise to clinical reality: the Chinese experience

Thoracic electrical impedance tomography (EIT) has emerged as a powerful, non-invasive, and radiation-free tool for real-time bedside monitoring of regional lung ventilation and perfusion. Its unique ability to visualize spatial and temporal heterogeneity has established clinical value across intensive care, perioperative management, and chronic respiratory disease settings. Despite decades of recognized potential, the global translation of EIT from laboratory research to routine clinical practice has faced significant challenges, including high device costs, lack of standardization and guidelines, workflow integration challenges, and insufficient evidence linking its use to clinical outcomes. China's experience over the past decade presents a compelling and instructive case of rapid adoption that contrasts sharply with the slower global pace. Unlike prior descriptive reviews that catalogued milestones achieved, this article provided an analytical framework that examined how and why this accelerated translation occurred in China. It first evaluated the specific clinical value driving adoption across diverse scenarios. It then identified the distinctive ecosystem that enabled this rapid translation. Several factors worked synergistically: rapid clinical validation was achieved through China's vast hospital network. Domestic industry innovation drove down device costs and improved portability. Chinese researchers provided proactive leadership in building national and international standards. Most importantly, strategic government support-including reimbursement policies-removed economic barriers to adoption. Transferable lessons from this model were discussed for overcoming implementation barriers and accelerating the adoption of innovative medical technologies globally.
