It is equipped with advanced technologies such as ECMO, hemodynamic monitoring, continuous bedside purification, IABP, brain function monitoring, and critical care ultrasound.

Over the past decade, the ICU has advanced in medical technology, education, and research, becoming a critical care center for southern Hainan. In 2020, it was designated as a residency training base and clinical drug trial base. The department has led 2 provincial and municipal research projects and published over 10 professional papers.
