Dr. Fu specializes in the rescue of critically ill patients and perioperative care for cardiac patients, particularly in areas such as airway management, mechanical ventilation, percutaneous tracheostomy techniques, fiberoptic bronchoscopy, deep venous and arterial catheterization, cardiopulmonary resuscitation, nutritional support, pain management, bedside blood purification, ECMO technology, shock management, sepsis, and multi-organ failure treatment. He has nearly 20 years of experience in critical care medicine and is well-equipped to address complex cardiovascular conditions and rescue critically ill patients.

During his tenure, he has introduced several new technologies in critical illness care, including percutaneous tracheostomy, PICCO invasive hemodynamic monitoring, non-invasive hemodynamic monitoring, pulmonary artery floating catheter techniques, fiberoptic bronchoscopy for alveolar lavage, non-invasive ventilation for respiratory and circulatory failure, enteral nutrition, BISS-guided sedation techniques, intra-aortic balloon pump (IABP) for cardiogenic shock, and sodium citrate anticoagulation in blood purification. His efforts have saved many critically ill patients.

He has received seven provincial-level medical technology awards, participated in one provincial research project, and published over ten articles in national medical journals, including one in a SCI-indexed journal.
