What is critical care medicine? Critical care and treatment is a clinical discipline that has emerged in recent years, with the aim of providing technical and high-quality medical services for patients with life-threatening acute serious illnesses, i.e., monitoring physiological functions, life support, preventing and controlling complications, and promoting and accelerating the recovery process of patients with critical illnesses, which is a higher level of medical services after the continuation of resuscitation, and is the modernization of society and the development of medical science. The inevitable trend. In recent years, with the continuous progress of high-tech, a variety of testing and support equipment widely used in clinical, the popularity and standardization of ICU wards, people’s understanding of the physiological functions of life is gradually improved, therefore, to improve the support and protection of the failing organs, so that the success rate of rescue of critical and serious diseases significantly increased, many patients with critical and serious diseases under close supervision and careful treatment, through the most difficult moments of life Many critically ill patients have passed the most difficult moments of their lives under close supervision and careful treatment, and are gradually moving towards recovery. At the same time, it also drives and promotes the progress and development of other clinical disciplines. The basic technical requirements of ICU physicians should include the following: the ability of cardiopulmonary cerebral resuscitation; the ability of respiratory support (tracheal intubation, mechanical ventilation, etc.); the ability of continuous electrocardiographic monitoring; the ability to identify and deal with arrhythmias and invasive hemodynamic monitoring; the ability to perform emergency temporary cardiac pacing; the ability to respond quickly to various laboratory results and give immediate feedback; the ability to support the function of multiple stolen organs; the ability to perform total parenteral nutrition; and the ability to perform the function of the cardiovascular system. The ability to perform total parenteral nutrition; the ability to administer microinfusions; the ability to master a variety of monitoring techniques, as well as a variety of operational techniques; the ability to provide life support during patient transport (with the ability to administer oxygen, ventilators, electrocardiographic monitoring); the ability to provide emergency treatment for various medical specialties. The Chinese translation of ICU is not yet unified, the mainland is generally translated as “monitoring ward” or “intensive care unit”, while in Hong Kong it is translated as “intensive care unit”. From the original text, the word Intensive translated as “strengthen” seems to be no doubt, but the meaning of Care can be deduced, it includes the “care” and “treatment” two layers of meaning. The word “care” may be translated as “guardianship” using modern concepts. Therefore, some people believe that ICU may be more accurately translated as “intensive care unit”. In fact, ICU is also characterized by extensive and close monitoring of physiological functions, and making judgments and treatments accordingly. Regardless of the name, the basic purpose of the ICU is to provide better quality care for critically ill patients. Because ICUs are at the forefront of medical development and are the most dynamic form of critical care medicine, they are extremely pioneering, able to push the envelope from theory to clinical practice, and to do things that are difficult to do in the general ward. But on the other hand, no matter how “special” ICU is, it is based on medical development after all, and the meaning of “strengthening” is actually just a condensation of existing methods and means, so it cannot surpass the development of the times and do what medicine has not been able to do so far. A full understanding of this can regulate the behavior of the ICU, and at the same time relieve the doubts and misunderstandings of some people. ICU is an abbreviation of IntensiveCareUnit, which means Intensive Care Unit. Intensive Care Unit is a form of medical organization and management that integrates modern medical and nursing technology with the development of medical and nursing specialties, the birth of new medical equipment and the improvement of hospital management system. It is a ward in small and medium-sized hospitals and a special department in large hospitals, where critically ill patients are pooled together and given the best protection in terms of human, material and technical resources, with a view to obtaining good treatment results. ICU has a history of more than 30 years in the world, and has become the center of rescue for critically ill patients in hospitals. how the level of supervision in ICU, whether the equipment is advanced, has become an important symbol to measure the level of a hospital. ICU in China started late, in the early 80s, and it is not common to have ICU in China, but it has been paid attention to and is estimated to develop rapidly. CCU is one of the specialized ICU, and the first C is the abbreviation of Coronaryheartdisease, which is specifically for severe coronary heart disease. The ICU has a central monitoring station, which directly observes all monitored beds. The ICU mainly treats: (1) patients with severe trauma, after major surgery, and those who need continuous and close monitoring of vital indicators and supporters; (2) those who need cardiopulmonary resuscitation; (3) those who have organ failure (including heart, brain, lung, liver and kidney) or multiple organ failure; (4) patients with severe shock, sepsis and poisoning; (5) those who need monitoring and enhanced treatment before and after organ transplantation. (5) Patients who need monitoring and intensive treatment before and after organ transplantation. ICU equipment must be equipped with bedside monitors, central monitors, multifunctional respiratory therapy machines, anesthesia machines, ECG machines, defibrillators, pacemakers, infusion pumps, microinjectors, tracheal intubation and emergency equipment needed for tracheotomy. In hospitals with better conditions, they are also equipped with blood gas analyzers, microelectronic computers, electroencephalography machines, ultrasound machines, bedside line transfer machines, hemodialysis machines, intra-arterial balloon counterpulsators, routine blood and urine analyzers, blood biochemistry analyzers, etc. Since ICU is a modern medical equipment to monitor and treat patients in critical condition, the personnel working in ICU must have a strong theoretical knowledge of medical fundamentals, rich clinical experience, strong resilience, and the ability to master the operation of complex instruments.
