Basal crackles are crackles apparently originating in or near the base of the lung. Bibasal crackles, also called bilateral basal crackles, are crackles heard at the bases of both the left and right lungs. Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration.
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

An X-ray uses high-frequency electromagnetic radiation to visualize the human body. In the case of choking, a chest X-ray is obtained to visualize the lungs and upper airway. However, many objects do not show up on X-ray (radiolucent). [25] About 10% objects are radio-opaque and can be visualized using X-ray.
This type of abnormality is commonly seen in flock worker's lung. Signs and symptoms of flock worker's lung include rales (crackling noises caused by fluid in the lungs), dyspnea (shortness of breath), and coughing. Abnormalities seen on a computed tomography (CT) scan of the lungs can include ground glass opacity and reticular opacity.
Contused lungs are less able to remove bacteria than uninjured lungs, predisposing them to infection. [67] Intubation and mechanical ventilation further increase the risk of developing pneumonia; the tube is passed through the nose or mouth into the airways, potentially tracking bacteria from the mouth or sinuses into them.

Other symptoms: Ant bites are typically painful and itchy. In addition to the bites, fire ants use their stinger to inject a venom called solenopsin, which causes a burning sensation, Frye says.
The tissue in the lungs becomes thick and stiff, which affects the tissue that surrounds the air sacs in the lungs. [7] Symptoms typically include gradual onset of shortness of breath and a dry cough. [1] Other changes may include feeling tired, and clubbing abnormally large and dome shaped finger and toenails. [1]
