Pneumatic Dilation Pneumatic Dilation. Pneumatic dilation is an endoscopic therapy for achalasia. An air-filled cylinder-shaped balloon disrupts the muscle fibers of the lower esophageal sphincter, which is too tight in patients with achalasia. How is pneumatic dilation performed? During an outpatient upper endoscopy, the endoscopist passes a catheter with a deflated balloon through the mouth and into the stomach. The balloon is centered over the lower esophageal sphincter and inflated with air.

What is the difference between a bronchi and a bronchiole? Bronchi (plural of bronchus) are tubes that branch off from the trachea into each lung. Bronchioles are smaller tubes that branch off from each bronchus. Also there are only two bronchi compared with the hundreds of bronchioles.

Bronchiectasis: Current Concepts in Pathogenesis, Immunology, and Microbiology Bronchiectasis is, in essence, a pathological end point consisting of abnormal, permanent dilatation of the bronchi and airway obstruction, as identiﬁed in lung-function studies. (2–4). This end point can be reached by many different routes (Table 1).

What are the Bronchioles? The bronchioles are part of the airway passages in the lungs. They are located at the end of the bronchi, the larger, branching airway passages in the lungs, and terminate in the alveoli, tiny circular sacs where oxygen is exchanged with carbon dioxide in the blood.

Bronchi and Bronchioles - Anatomy & Physiology The bronchi and bronchioles are parts of the 'Conduction Zone' of the respiratory system - allowing the passage of air from the external environment into the lungs where gaseous exchange can take place. The conduction zone is also known as dead space, and no gaseous exchange can take place in this area.

Bronchi and Bronchioles The main function of the bronchi and bronchioles is to carry air from the trachea into the lungs. Smooth muscle tissue in their walls helps to regulate airflow into the lungs. When greater volumes of air are required by the body, such as during exercise, the smooth muscle relaxes to dilate the bronchi and bronchioles.

Some or all of the following symptoms are present with bronchiolitis. 1  Wheezing: a high-pitched whistling noise when your child breathes out. 2  You may actually hear this yourself, or a physician may hear wheezing when she listens to your child. 3  Rapid breathing: at a rate of 40 breaths per minute or faster.

- 1 Pathologic dilation of the proximal and medium sized airways from weakening or destruction of their walls. 2  Three major causes are: obstruction, infection and traction, the most common being infectious.  Bronchiectasis may occur when there is prolonged partial obstruction, e.g. slow- growing neoplasms, foreign bodies.

Bronchiectasis NOTE: This is the Professional Version. Bronchiectasis is dilation and destruction of larger bronchi caused by chronic infection and inflammation. Common causes are cystic fibrosis, immune defects, and recurrent infections, though some cases seem to be idiopathic. Symptoms are chronic cough and purulent sputum expectoration; some patients may also have fever and dyspnea.

- Rhonchal fremitus, also known as bronchial fremitus, is a palpable vibration produced during breathing caused by partial airway obstruction. The obstruction can be due to mucus or other secretions in the airway, bronchial hyperreactivity, or tumors.actile fremitus, known by many other names including pectoral fremitus, tactile vocal fremitus, or just vocal fremitus, is a vibration felt on the patient's chest during low frequency vocalization.

Bronchospasm Definition. Bronchospasm is an abnormal contraction of the smooth muscle of the bronchi, resulting in an acute narrowing and obstruction of the respiratory airway. A cough with generalized wheezing usually indicates this condition. Bronchospasm is a chief characteristic of asthma and bronchitis.Description. Bronchospasm is a temporary narrowing of the bronchi (airways into the lungs) caused by contraction of the muscles in the lung walls, by inflammation of the lung lining, or by a combination of both.This contraction and relaxation is controlled by the autonomic nervous system.efinition. Bronchospasm is an abnormal contraction of the smooth muscle of the bronchi, resulting in an acute narrowing and obstruction of the respiratory airway.
