Since 1994, I have been engaged in clinical work in respiratory medicine. In 1997, I underwent specialized training in SICU clinical work within the respiratory medicine department. Starting in 2001, I served as an attending physician in the emergency department of pulmonary medicine, and in 2005, I obtained the qualification of associate chief physician in respiratory medicine. I have long been involved in the diagnosis and treatment of acute and critical illnesses in respiratory medicine, accumulating extensive clinical experience in rescuing critically ill patients with respiratory diseases, such as acute exacerbations of chronic obstructive pulmonary disease, acute attacks of bronchial asthma, refractory pneumothorax, massive hemoptysis, and respiratory failure. I am proficient in clinical procedures including non-invasive and invasive mechanical ventilation, endotracheal intubation, bedside bronchoscopic suctioning, and endotracheal tube replacement. I have published 6 papers as the first author or corresponding author, including 1 SCI paper (IF 4.6).
