How to check for acute respiratory failure

Acute respiratory failure requires a comprehensive examination, including arterial blood gas analysis, chest imaging, lung function tests, heart ultrasound, etc., to determine the cause and severity of the disease, so as to develop a corresponding treatment plan. Acute respiratory failure requires a comprehensive examination to determine the cause and severity of the disease, so as to develop a corresponding treatment plan. The following are some common examinations: 1. Arterial blood gas analysis: this is an important indicator to evaluate respiratory function, which can understand the partial pressure and pH of oxygen and carbon dioxide in blood, and help judge whether there is hypoxia and acidosis. 2. Chest imaging examination: such as X-ray, CT, etc., can check the structure and pathological changes of lungs, and exclude lung infection, pneumothorax, pleural effusion and other causes of respiratory failure. 3. Pulmonary function examination: including vital capacity, forced vital capacity, residual volume and other indicators, which can evaluate the ventilation function and diffusion function of the lungs, and are of great significance for diagnosing and evaluating the type and severity of respiratory failure.4. Cardiac ultrasound: It can evaluate the structure and function of the heart and exclude respiratory failure caused by cardiogenic factors.5. Other examinations: According to the specific situation, blood routine, blood biochemistry, pathogen detection, EEG and other examinations may be needed to understand the general situation and etiology. It should be noted that for patients with acute respiratory failure, the examination should be carried out under the guidance of a doctor. According to the specific situation of the patient, the appropriate examination method should be selected, and combined with clinical manifestations and other examination results for comprehensive analysis. At the same time, the key to treating respiratory failure is to correct hypoxia and acidosis in time, keep respiratory tract unobstructed, and carry out mechanical ventilation when necessary.
