• trachea
  • In some cases, a bronchoalveolar lavage may be carried out - an endoscope is used to look down the trachea, and mucus and cells are washed out of the lower airways for analysis. (wikipedia.org)
  • lungs
  • When the horse inhales these particles, they cause an inflammatory reaction in the small airways of its lungs. (usask.ca)
  • When an inflammatory reaction occurs in the horse's lungs, the airways narrow and there's an excessive production of mucus secretions - both of which contribute to airway obstruction and difficulty in breathing. (usask.ca)
  • However, bacteria in the lungs may perpetuate the condition and contribute to damage of the airways. (usask.ca)
  • To perform a BAL, your veterinarian will pass a long tube up the horse's nostrils and down into the lungs until it wedges in one of the small airways. (usask.ca)
  • The airway is a complex system of tubes that conveys inhaled air from your nose and mouth into your lungs. (aarp.org)
  • An obstruction may partially or totally prevent air from getting into your lungs. (aarp.org)
  • potentially
  • As the condition progresses, the airway is potentially compromised, due to the spread of infection to involve the floor of the mouth and pharyngeal spaces, resulting in a characteristic hardened induration of these spaces bilaterally and an elevation of the tongue. (wikipedia.org)
  • upper
  • It can be broadly classified into being either in the upper airway or lower airway. (wikipedia.org)
  • Infants and children under age 4 are particularly at risk for choking on food or small objects because their upper airways are smaller, they are less experienced in chewing food properly, and they tend to explore things with their mouths. (nyhq.org)
  • neck
  • Additional tests may include a CT scan of the head, neck, or chest to determine other sources of obstruction, such as epiglottitis. (aarp.org)
  • The infection may rapidly spread to other fascial spaces of the head and neck, further compromising the airway. (wikipedia.org)
  • risk factors
  • 0.70 and ‚Č•LLN) are a healthy population (i.e., they are elderly, asymptomatic subjects without the presence of known risk factors for chronic airways obstruction) or whether these in-between cases might represent subjects at risk who should be followed carefully. (hindawi.com)
  • high
  • A high-pitched squealing noise may be present as a result of air being forced through narrowed airways. (usask.ca)
