Symptoms of Lung Infections These symptoms are called lung infections

Lung infection is a very troublesome thing, our lungs are an important organ of our breathing, so do you know what the symptoms of lung infection are, what is the treatment of lung infection, let's learn about lung infection together.

In general, patients with lung infections will have some respiratory symptoms, such as cough, sputum production, etc., but there are also some atypical lung infections that will show gastrointestinal symptoms.

The pathogen of lung infection is complex, according to the different pathogens, it is divided into viral pneumonia, bacterial pneumonia and fungal pneumonia, etc., because of its various types, so the disease itself is complex, and different types of pneumonia have different risks of complications, once the complications occur, it increases the difficulty of diagnosis, the symptoms are more and more complex, and there are many complications caused by different course of disease, which is the reason for the complexity of lung infection symptoms.

Viral pneumonia

myocarditis

Influenza virus pneumonia has been reported to be complicated by myocarditis.

Secondary bacterial pneumonia

The most common pathogenic bacteria in lung infections are Streptococcus pneumoniae, Staphylococcus aureus or Haemophilus influenzae.

The patient's condition progressively worsens, or worsens after temporary improvement, with cough, purulent sputum, and signs of lung consolidation, with patchy and patchy opacities on x-ray. Reye syndrome.

Bacterial pneumonia

Patients with severe sepsis or toxemia are prone to septic shock, especially in older people. It is manifested as decreased blood pressure, cold extremities, excessive sweating, giving, tachycardia, arrhythmia, etc., while symptoms such as high fever, chest pain, and cough are not prominent.Other complications include pleurisy, empyema, pericarditis, meningitis, and arthritis.

In Staphylococcus aureus pneumonia, pneumothorax is predisposed to develop. At this time, the high fever persists or the body temperature drops and then rises again, coughing frequently, shortness of breath, unable to lie dry, and one side of the chest is full.

Here are some common complications of lung infections

Hypoxic encephalopathy

When pneumonia causes dyspnea and lack of oxygen, pneumonia patients will have vomiting and headache, and will also have coma and fainting, which is more dangerous.

Lung abscess

The inflammation of the lungs does not dissipate, forming an abscess, which can be one or more, coughing up a large amount of purulent sputum with a strong odor.

Bronchiectasis

Long-term obstruction of the bronchial tubes, atelectasis, causing bronchiectasis, can also be caused by frequent coughing, often following acute pneumonia.

The lungs are internal organs that are in direct contact with the outside world, so they are more susceptible to infection, and the elderly have poor physical function, and the probability of lung infection is greater than that of young people, especially those with cardiovascular and cerebrovascular diseases, diabetes, cancer or lung diseases themselves, as well as the elderly who have been bedridden for a long time, are high-risk groups.

If lung infection is not controlled in a timely and effective manner, it will develop into severe pneumonia, resulting in a considerable proportion of respiratory failure, so patients should not only pay attention to their cardiovascular and cerebrovascular diseases, but also pay more attention to the lungs and do a good job of prevention.

The causes of lung infection are mostly inhalation injury, tracheotomy or intubation, aspiration, pulmonary edema, atelectasis, shock, surgical anesthesia, invasive wound infection, purulent thrombophlebitis, etc.

Etiological classification of pulmonary infection

1. Bacterial pneumonia such as Streptococcus pneumoniae, namely pneumococcus, Staphylococcus aureus, type A hemolytic streptococcus, Klebsiella pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, Escherichia coli, Pseudomonas aeruginosa, etc.

2. Pneumonia caused by atypical pathogens such as Legionella, Mycoplasma and Chlamydia.

3. Viral pneumonia such as coronavirus, adenovirus, influenza virus, cytomegalovirus, herpes simplex virus, etc.

4. Fungal pneumonia such as Candida albicans, Aspergillus, radioactive bacteria, etc.

5. Pneumonia caused by other pathogens such as rickettsia, toxoplasmosis, protozoa, parasites such as pulmonary hydatids, pulmonary flukes, pulmonary schistosomiasis, etc. People with weakened immunity, such as AIDS patients, are prone to pulmonary infections such as Pneumocystis carinii, Legionella, Mycobacterium avium, tuberculosis, and Toxoplasma gondii.

6. Pneumonia caused by physical and chemical factors, such as radiation pneumonitis, gastric acid inhalation, chemical pneumonia caused by drugs, etc.

7. Mycoplasma pneumonia is caused by pneumoniac bronchia.

Bacterial pneumonia, viral pneumonia, and pneumonia caused by atypical organisms are common causes and are mostly related to external viruses and decreased immune function.

Bacterial pneumonia

It mainly has infectious and physicochemical properties such as radiation, toxic gas, drugs and allergic reactions such as hypersensitivity pneumonitis, and most of the clinical findings are infectious pneumonitis caused by bacteria, viruses, chlamydia, mycoplasma, rickettsia, fungi and parasites, among which bacteria are the most common.

Viral pneumonia

Viral pneumonia is an inhalation infection, transmitted through droplets from person to person, mainly caused by the downward spread of upper respiratory tract viral infection, often accompanied by tracheobronchitis, of which influenza virus is common, others are parainfluenza virus, cytomegalovirus, adenovirus, rhinovirus, coronavirus and some enteroviruses, such as coxsackie, echovirus, etc., as well as herpes simplex, varicella-zoster, rubella, measles and other viruses.Pneumonia is also common in infants and young children from respiratory syncytial virus infection.

Fungal pneumonia

Primary fungal pneumonia is mostly caused by Blastomyces dermatitis, Histoplasma capsulatum or Coccidioides vulgaris, followed by the genera Sporotricha schenckii, Cryptococcus, Aspergillus or Mucormyces.

Fungal pneumonia may be a comorbid condition of antimicrobial therapy, particularly in patients with weakened defenses due to severe illness or immunosuppressive therapy and AIDS. Although there are other pathogens, they are not pathogenic in immunocompetent people.

Pneumonia caused by atypical pathogens

Mycoplasma inflammation, Chlamydia pneumoniae, and Legionella are considered to be the representative causative microorganisms among atypical pathogens and are all intracellular pathogens.

The main pathogens of this type of pneumonia are Mycoplasma pneumoniae pneumoniae and Chlamydia pneumoniae, and Legionella pneumonia is also classified as "atypical pneumonia" because of its significant extrapulmonary symptoms, which are different from typical pneumonia.

Legionella is a bacillus G, while mycoplasma and chlamydia are classified as a separate group, but they can live independently, grow on cell-free media, multiply in binary divisions, and are sensitive to macrolides and quinolone antibiotics, so some people call them "bacteria-like".

The most common type of lung infection is pneumonia, which also includes inflammation of the lung parenchyma including the terminal airways, alveolar cavity and lung interstitium.

Through the above introduction, we must have a more comprehensive understanding of the symptoms of lung infection, our lungs are relatively fragile parts, and if our lungs are invaded by bacteria, it will lead to infection, so we should pay attention to protecting our lungs in our daily life.
