![]() In case of bacterial pneumonia, a child usually becomes sick very quickly, and experiences a sudden onset of high fever and rapid breathing. One can cough, have fever, and may find it difficult to breathe. It often occurs after an attack of cold and flu. This type of lung infection can occur in both the lungs due to bacteria or viruses. Eventually, the condition results in further breakdown of the airways. This leads to increased amount of bacteria in the lungs, and airway blockage. The affected bronchi cannot clear secretions. Due to an excessive inflammatory response, the function of the airways gets severely affected. Conditions such as pneumonia, tuberculosis, and cystic fibrosis, etc., can lead to bronchiectasis. It is a type of obstructive lung disease. Permanent enlargement of certain parts of the airways in the lungs is described as bronchiectasis. Poor lung function can lead to difficulty in breathing. Whole-body inflammation can trigger a cascade of changes that can damage multiple organ systems, causing them to fail. However, a fungal, viral, or parasitic infection can also cause sepsis. A severe bacterial infection can cause sepsis. Sepsis occurs when these chemicals trigger inflammatory responses throughout the body. Smoking is the most common cause of this condition, and one has to stop smoking to overcome or get rid of it.Īs you know, our body releases certain chemicals to fight an infection. The bronchial tubes continue to be swollen, irritated, and produce excessive mucus over time. Chronic bronchitis effects can be mild or severe, but they last for months or years. On the other hand, chronic bronchitis occurs when there is an injury to the epithelium of the bronchi leading to chronic swelling. Cough is the most common symptom of acute bronchitis. The person experiences difficulty in breathing, as swelling narrows the airways. It results in increased secretion of mucus. Swelling and inflammation in the passages that carry air to the lungs is called acute bronchitis. What Causes Crackles In the Lungs Acute or Chronic Bronchitis The crackles which originate at the bases of both the lungs, are known as bibasilar or bibasal crackles, or bilateral basilar crackles (basal crackles in both the lungs). When the crackles originate in or near the base of a lung, they are known as basilar or basal crackles (basal rales). When such noises come out of both the lungs, they are referred to as bilateral crackles. If a person is suffering from a respiratory disease, either one of his lungs or both his lungs can make crackling noises while breathing (inhaling and exhaling air). They can be heard on intake or release of air. Such popping sounds are heard when air is forced through the respiratory passages that are narrowed or closed by fluid, mucus, or pus. They can be described as small clicking, bubbling, or rattling sounds in the lungs.
