With the aging of society’s population and the improvement of medical technology, various respiratory diseases that impair respiratory function continue to increase, such as severe chronic obstructive pulmonary disease and pulmonary heart disease, which often occur due to infection or after chest and abdominal surgery. Decompensated acute respiratory failure, and acute respiratory failure caused by various causes, such as adult respiratory distress syndrome. In the past 20 years, due to the continuous improvement of ventilators and other medical equipment, clinical practice has made great progress in respiratory failure rescue. Many large hospitals and medical centers have now established respiratory care units for critically ill patients to train professional medical personnel and develop respiratory care and rescue medical equipment. Through systematic research on the pathogenesis, pathophysiology, and respiratory support of respiratory failure, artificial airway mechanical ventilation through incision and nasotracheal intubation was carried out to correct hypoxia and carbon dioxide retention, as well as acid-base balance and electrolyte imbalance, and control infection. Active rescue such as feeding, nasogastric feeding or intravenous hypernutrition has saved the lives of many patients. Because respiratory monitoring is closely integrated with clinical practice, the pathogenesis and triggering factors of some respiratory dysfunction diseases, such as sleep apnea syndrome and hypoventilation syndrome, have been understood, thus providing theoretical and practical guidance for early diagnosis and reasonable prevention and treatment. Nowadays, transnasal or oronasal mask mechanical ventilation has achieved promising results in the treatment of this syndrome.
With the development of science, technology and medicine, people are not only satisfied with the diagnosis and treatment of diseases, but more importantly, how to prevent diseases, maintain and restore respiratory function, prolong life and improve quality of life. Environmental protection laws have been enacted both at home and abroad, and May 31st every year is World No Tobacco Day to improve the quality of life. But this is a beginning. The basic theories and technologies of respiratory rehabilitation medicine have yet to be studied in depth. The 21st century will be an era of development of respiratory rehabilitation medicine. Respirology is a developing discipline, and many respiratory diseases are not yet understood. In order to further improve the prevention and treatment of respiratory diseases, it is necessary to work closely with clinical and basic and peripheral disciplines to continuously discover, analyze and solve problems in the field of respiratory diseases. problems, achieve greater results, and treat more patients.
