With the development of medical nursing specialty, the birth of new medical equipment and the improvement of hospital management system, intensive care is a medical organization and management form that combines modern medical nursing technology. Small and medium-sized hospitals are a ward, and large hospitals are a special department. Only by focusing on critically ill patients and giving them the best protection in manpower, material resources and technology can we get good treatment results. Specifically, it is to use advanced medical monitoring equipment (such as continuous ECG, blood pressure, blood gas monitoring, etc. ) and put in high-quality personnel with good technical level to monitor patients who need monitoring for 24 hours, deal with problems immediately when they are found, and respond to changes at any time.
