How do we know if it's pneumonia?
VerifiedYour well-being is my goal.
Pneumonia can be judged comprehensively by symptoms, signs, imaging, laboratory tests and etiological tests. To judge whether pneumonia is present, it can be judged comprehensively by the following aspects: 1. Symptoms: Common symptoms of pneumonia include fever, cough, expectoration, dyspnea, etc. If these symptoms occur, especially persistent fever or worsening cough, pneumonia should be highly suspected. 2. Signs: The doctor will perform auscultation of the lungs to check for abnormal signs such as rales and wheezing. However, these signs are not specific to pneumonia, and similar signs may occur in other diseases. 3. Imaging: Chest X-ray or CT examination can help doctors observe the condition of the lungs, whether there are typical manifestations of pneumonia such as inflammatory infiltration and consolidation. 4. Laboratory tests: such as blood routine, C-reactive protein, etc., can help determine whether there is an inflammatory reaction. 5. Etiological examination: If conditions permit, etiological tests, such as sputum culture, PCR testing, etc., can be performed to determine the type of pathogen and help select appropriate treatment drugs. It should be noted that the above methods are only the basis for preliminary judgment of pneumonia, and the final diagnosis needs to be combined with clinical symptoms, signs, imaging tests and laboratory tests. For high-risk groups, such as the elderly, children, immunocompromised persons, etc., once respiratory symptoms occur, they should seek medical attention in time, and conduct detailed examination and treatment. At the same time, maintaining good personal hygiene habits, such as washing hands frequently and wearing masks, can help prevent pneumonia.
