[Promoting critical care system and capacity building in pulmonary and critical care medicine subspecialties].

The development of respiratory medicine has evolved from the prevention and treatment of tuberculosis in 1950 s to the care of chronic obstructive pulmonary disease and corpulmonale disease in 1970 s. In the past 20 years, it has further advanced into the integration of pulmonary medicine (PM) and critical care (CC), becoming a dominant form of global disciplines in respiratory medicine. The subspecialty training system of pulmonary and critical care medicine (PCCM) is a decisive measure to ensure the standardized development of respiratory medicine, and medical intensive care unit (MICU) is the most important clinical practice field for respiratory medicine in China, which plays a crucial role in promoting the substantial construction of the critical care medical system within the PCCM subspecialty, thus contributing to the development of the discipline.
