Acute respiratory failure: Emergency life-line response and scientific treatment of acute respiratory failure is a clinical emergency that threatens the safety of life by the rapid reduction of respiratory function due to a variety of sudden-onset factors. This paper aims to present, in a general manner, the mechanisms for the occurrence of acute respiratory failure, clinical performance, diagnostic methods, treatment strategies and preventive measures, with a view to providing valuable information to the public and health workers. At the same time, the literature will be used to support the accuracy and scientific nature of the discussion.The mechanisms for the occurrence of acute respiratory failure are complex and varied, and include, inter alia, two main categories of aerobic and aerobic disorders. Aerobic dysfunctions are caused mainly by air-traffic congestion, respiratory paralysis and pectromorphosis, leading to gas exchange barriers between lung bubbles and the external environment. Gas-replacement functional disorders are mainly caused by, inter alia, pneumoconiosis, pneumatic pulmonary hysteria and gaseous dissipation disorders, resulting in gas exchange barriers between pneumoconiosis and pneumatic vasculars.In actual cases, the occurrence of acute respiratory failure is often associated with a combination of factors. For example, acute events such as drowning, electroshock, and drug poisoning may result in respiratory depression or respiratory paralysis, which can cause respiratory failure. In addition, severe trauma, infection, shock, etc. can also cause lung tissue damage or functional impairment, leading to acute respiratory failure.Clinical performance. The clinical behaviour of acute respiratory failure is diverse and severe, and includes, inter alia, respiratory difficulties, purple laceration, increased heart rate, blood pressure decline, and cognitive disorders. Respiratory difficulties are the most common symptoms of acute respiratory failure, and patients often feel that they are suffering from stress, faster or slower breathing, and poor respiratory rhythms. Chrysotile is due to a lack of oxygen which results in the cyanide of skin, mucous membranes, etc. An accelerated heart rate and a decrease in blood pressure are common symptoms of the circulatory system of acute respiratory failure that can cause shock in serious cases. Mental disorders are manifested in irritation, sleep addiction and coma, and are important signs of acute respiratory failure that endangers life.The diagnosis of acute respiratory failure is based mainly on clinical performance, haematological analysis and visual examination. Blood and gas analysis is the gold standard for the diagnosis of acute respiratory failure, which can be judged by the type and severity of respiratory failure by the determination of an arterial O2 (PaO2) and an arterial carbon dioxide (PaCO2). Visual examinations, such as chest X-rays, CTs, etc., help to detect abnormalities such as lung pathologies and air-traffic barriers and provide important leads for diagnosis. Examinations such as electrocardiograms, ultrasound cardiac maps help to assess heart function and to remove respiratory failure caused by heart disease.Treatment strategies. The key to the treatment of acute respiratory failure lies in the rapid correction of oxygen deficiency and carbon dioxide retention, while actively addressing both primary and complications. The treatment strategy includes the following:
1. Respiratory flow: In cases of respiratory inaccessibility, respiratory circulants should be removed in a timely manner and, if necessary, artificial airways should be established by means of tube intubation, bronchial cut-off, etc., to ensure smooth entry of oxygen and drugs.
Oxygen: Oxygen therapy is an important measure to correct oxygen deficiency. Suitable Oxygen Treatment is selected according to the patient ‘ s circumstances. The use of a respirator for mechanical ventilation may be considered if the supply of high oxygen levels does not improve the violet.
3. Drug treatment: The choice of appropriate medications, such as antibiotics to control infections, urea to reduce oedema, bronchial expansion to mitigate gastric convulsions, etc., is based on the specific circumstances of the patient. At the same time, close attention should be paid to changes in the vital signs and conditions of patients and to the timely adjustment of treatment programmes.
4. Mechanical ventilation: In cases of severe respiratory failure, the assisted breathing shall be performed in a timely manner using mechanical ventilation. Mechanical ventilation includes both non-inventory and inventive modes, and the appropriate mode and parameters should be selected according to the patient ‘ s specific circumstances. Uninvented gas is carried out mainly through masks or nose masks, which have the advantages of simplicity of operation, small trauma, etc.; and incubation requires the establishment of artificial airways, such as catheters or trachea, for patients with severe and non-invasive conditions.
5. Correcting alkaline balance disorder and electrolyte disorder: People with acute respiratory failure often suffer from alkaline balance disorder and electrolytic disorder, which should be corrected in a timely manner based on blood-gas analysis. At the same time, the electrolyte levels of patients should be closely monitored and treatment programmes adjusted in a timely manner.
The key to the prevention of acute respiratory failure lies in strengthening health education, self-protection awareness and capacity. People with high-risk factors, such as the elderly, children, chronically ill, should undergo periodic health examinations to detect and treat potential diseases in a timely manner. In addition, long-term exposure to harmful gas conditions should be avoided, good living and eating habits should be maintained and body immunity should be enhanced.Shanghai: Shanghai Science and Technology Press, 2005: 68-75.2.
