  • Cannulation of the thoracic duct followed by embolization should be considered in those patients who are shown to have leakage of lymphatic fluid into the airway. (wikipedia.org)
  • In the asthmatic group, a significant positive correlation was found between airways resistance and bronchial dilatation score (p = 0.01), and between small airways obstruction index and mosaic perfusion score (p = 0.05). (nih.gov)
  • In addition, both FEV1 and reversibility of small airways obstruction values correlated with air-trapping score (p = 0.03 and p = 0.007, respectively). (nih.gov)
  • The main types of lung cancer are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). (healthwise.net)
  • Since large particles impact and sediment in the nares and the major airways, only relatively small particles enter the acini. (digitalfire.com)
  • However, even these patients are at risk of dying from lung cancer (both small and non-small cell types). (cancer.gov)
  • A light and a small camera on the bronchoscope allow the provider to look inside the lungs' airways. (stelizabeth.com)
  • Wheezing in Infants and Young Children Wheezing is a relatively high-pitched whistling sound that occurs during breathing when the airways are partially blocked or narrowed. (msdmanuals.com)
  • Therefore, there is a question as to its effectiveness when used in this way especially in the airway compromised patients that the anesthesia provider will commonly face in this situation. (scirp.org)
  • It is composed of an extensive branching system of airway passages that transmit the air from the atmosphere to the alveoli (the gas-exchange units). (medscape.com)
