Signs that severe pneumonia is getting better are usually not judged exactly the same for different types of patients with severe pneumonia. Family members generally cannot accurately determine the progress of the disease, and should be judged by the doctor in combination with clinical symptoms and examination results. 1. Reduction of pulmonary symptoms: Improvement in symptoms such as chest tightness, shortness of breath, coughing and coughing up pus sputum indicates that severe pneumonia is improving, where coughing symptoms may be heavy and then light because a large number of pathogenic microorganisms are eliminated at the beginning of pneumonia treatment and secretions with pathogenic microorganisms need to be discharged by coughing. 2. Signs Decrease: In most patients with severe pneumonia, dry and moist rales, wheezing and croup can be heard in the lungs of varying sizes. As the infection is controlled, pulmonary signs may be reduced; 3. Improvement in ventilator indications: judged by the patient’s oxygen concentration, respiratory rate, incidence of ventilator antagonism, and oxygenation status, etc. If good oxygenation can be maintained despite a decrease in oxygen concentration, this usually indicates signs of improvement in severe pneumonia; 4. Relief of systemic inflammatory response: as evidenced by laboratory tests for total white blood cell and neutrophil count, C The absorption of pulmonary lesions on chest X-ray: usually when the initial severe pneumonia lesions are compared with the treated lesions, the absorption indicates that severe pneumonia has significantly improved, which is a more powerful and reliable sign of improvement; 6. The pneumonia is considered to have some signs of improvement.
