  • Asthma is a clinical syndrome characterized by episodic reversible airway obstruction, increased bronchial reactivity, and airway inflammation. (medscape.com)
  • Asthma is characterized by reversible airway obstruction on bronchial challenge or more commonly by measuring the effect of a short-acting bronchodilator, when the subject is suffering with shortness of breath. (smtir.com)
  • During this surgery, a portion of the back of the tongue is removed to open up the airway. (lookeetech.com)
  • A procedure whereby the chin bone is divided into two parts, allowing the tongue to extend forward and prevent it from obstructing the airway. (lookeetech.com)
  • Other appliances can prevent the tongue from blocking the airway and obstructing air flow. (summitsmile.com)
  • This area is the collapsible part of the airway (see illustration) where the tongue and upper throat meet the soft palate and uvula. (entverobeach.com)
  • With partial obstruction, a "fan sound" or "flag flapping" sound can be heard during auscultation. (wikipedia.org)
  • Long interruptions of breathing (more than 10 seconds) during sleep caused by partial or total obstruction or blockage of the airway. (dreamsleeplk.com)
  • Chronic coughing develops as the body attempts to open and clear the bronchial airways of particles and mucus or as an overreaction to ongoing inflammation. (medicinenet.com)
  • A condition that results from the damage and dilation (widening) of the large bronchial airways. (prakriyahospitals.com)
  • Septoplasty corrects a deviated nasal septum, the internal cartilage that separates the two nasal airways. (drstoker.com)
  • When the septum is deviated, however, it restricts airflow through one or both nostrils. (drstoker.com)
  • The goal of septoplasty is to straighten the septum, open the nasal airways and repair the deviation. (drstoker.com)
  • A deviated septum obstructs the airflow through the nostrils into the body. (perkinslawtalk.com)
  • Deformities of the nose such as a deviated septum (a structural change in the wall that separates one nostril from the other) or nasal polyps can also cause obstruction. (dreamsleeplk.com)
  • NASAL DEFECTS - Deviated nasal septum or congestion of nasal passage, obstruct normal flow of air causing snoring. (buznit.com)
  • Once this occurs, the airway collapses, making it impossible to breathe. (lookeetech.com)
  • Wheezing Wheezing is a high-pitched, whistling sound that occurs during breathing when the airways are partially blocked. (msdmanuals.com)
  • Obstruction of normal breathing mechanism due to nasal congestion, sinuses, allergies, sleep apnoea, anatomic structural variation in nose and soft palate or alcohol consumption cause snoring. (buznit.com)
  • Many owners of brachycephalic dogs become used to the snoring and wheezing signs of airway compromise and perceive them as normal until a particularly severe attack occurs. (dognews.com)
  • This aims to open up the airway to allow for easier breathing and has also been done to treat snoring. (lookeetech.com)
  • The noisy sounds of snoring occur when there is an obstruction to the free flow of air through the passages at the back of the mouth and nose. (entverobeach.com)
  • Snoring occurs when the flow of air through the mouth and nose is physically obstructed. (dreamsleeplk.com)
  • When these structures vibrate and bump against one another the airway becomes obstructed, causing snoring. (dreamsleeplk.com)
  • The increase in airway obstruction forces the air to cause vibration of tissues that lead to loud snoring. (buznit.com)
  • The airway obstruction that cause snoring occurs in following conditions. (buznit.com)
  • If a person has an elongated uvula it leads to obstruction of air flow producing loud vibration that lead to snoring. (buznit.com)
  • A patient with obstruction while breathing with snoring having high blood pressure, obesity, nasal problems should consult a doctor. (buznit.com)
  • During sleep uvula vibrates, can block the air flow into the lungs causing obstructive sleep apnoea and loud snoring. (buznit.com)
  • Asthma: Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. (smtir.com)
  • Extended nasopharyngeal turbinates extend past the nose and into the pharynx, which is the area behind the nose and mouth, and cause obstruction of the airflow. (dognews.com)
  • When it deviates, it can block one side of the nose and reduce airflow. (ceenta.com)
  • Turbinates normally clean the air before it reaches the lungs, but in some cases they may actually obstruct normal airflow. (drstoker.com)
  • OSA is characterized by the repeated obstruction of the pharyngeal or upper airway during sleep. (lookeetech.com)
  • An important static factor that has been found is the reduced diameter of the pharyngeal airway in wakefulness in OSA patients compared with non-OSA patients. (ayurvedapc.blog)
  • This can result from ingestion or inhalation of an item that obstructs the airway, preventing normal breathing. (petplace.com)
  • The combination of bronchospasm and mucus hypersecretion creates airway obstructions, or narrowed airways. (asthma.net)
  • If the casts completely obstruct the airway, breath sounds will be decreased and dullness will be present with percussion. (wikipedia.org)
  • In this type, sufferers have issues taking a breath because of an obstruction in their airway, which generally takes place when they are resting in the evening. (doctordocker.com)
