What are the symptoms of lung infection

When the weather is bad with alternating hot and cold weather, people are prone to catching colds and coughing. If the cough lasts for a long time, it may cause lung infection. Therefore, during the coughing period, you must be careful not to catch cold again, and try to avoid recurrence of the disease. If it causes lung infection, it will be more troublesome. Normal colds are normal. Everyone will get sick and as long as they can recover in time, there will be no other complications. Let’s find out what are the symptoms of lung infection?

Difficulty breathing, temperature changes, cough, increased sputum volume and characteristics. Anaerobic infection combined with other pathogens may have clinical characteristics of anaerobic infection such as coughing up fecal sputum with pus and foul smell. Other types of multiple infections lack characteristic symptoms. In general, patients with multiple infections have more severe symptoms.

1. Wheezing or shortness of breath: Wheezing chronic bronchitis has bronchospasm, which can cause wheezing, often accompanied by wheezing. There was no shortness of breath in the early stages. When recurring attacks occur for many years and are complicated by obstructive pulmonary emphysema, they may be accompanied by shortness of breath of varying degrees. The patient may first have shortness of breath after labor or activity. In severe cases, the shortness of breath becomes worse with movement and the patient cannot take care of himself.

2. Coughing up phlegm: Because phlegm accumulates in the lumen after sleeping at night, getting up or changing body position will stimulate sputum discharge. Sputum is often more in the early morning. The sputum is usually white mucus or serous foam, and occasionally contains blood.

3. Cough: Bronchial mucosal congestion, edema or accumulation of secretions in the bronchial cavity can cause cough. The severity of the cough depends on the condition. It is usually more severe in the morning and lighter during the day. There are bouts of coughing or sputum discharge before going to bed at night.

When patients find that they have lung discomfort, they should go to the hospital for formal examinations. The main items of the examination are:

1. Pay attention to whether there is inhalation injury, tracheotomy or intubation, aspiration, pulmonary edema, atelectasis, shock, surgical anesthesia, invasive wound infection, suppurative thrombophlebitis, etc.

2. Pay attention to any breathing difficulties, temperature changes, cough, increased sputum volume and sputum characteristics. Clinical symptoms should be differentiated from burn toxemia or sepsis.

3. Physical examination. Patients with severe burns often have burns on their chests, making it difficult to obtain accurate chest signs. Therefore, careful examination should be performed to check for any respiratory changes or rales.

4. To identify the infecting bacteria, airway secretion cultures should be performed regularly, preferably bronchopulmonary lavage fluid cultures, to prevent contamination.

5. Chest X-ray. The diagnosis of most lung infections after burns depends on X-ray examination. Chest X-rays should be performed routinely after injury, and regular follow-up examinations should be performed thereafter. The X-ray manifestations of pneumonia can be divided into three types: small focal lesion, large focal lesion and lobar lesion, with small focal lesion pneumonia being the most common.

The above content is about the early symptoms and examination methods of lung infection. Although the treatment of lung infection is very simple and the condition can be controlled by medication, improper care in life will cause repeated attacks of the disease, which is very detrimental to the patient's health. Therefore, we must grasp the early symptoms of the disease and completely control the disease in the early stages so that it will not worsen and will have little impact on the body.
