Several factors are responsible for endotracheal tube obstruction, for instance patients biting the ETT tube, kinking of ETT tube, accumulation of secretions and blood clots, airway tissues such as A Case of Endotracheal Tube Obstruction - The Airway JediAug 10, 2015 · The blood clot had caused partial obstruction and an increasing CO2. An acute PCO2 above 70 is sedating and can lead to worsening hypoventilation leading to higher PCO2. Fortunately, when the first endotracheal tube was passed into the trachea, the clot lodged in the tube.
Manufacturing defects of endotracheal tube (ETT) are not so common but not so rare in anesthesia practice. The important thing is to identify these defects by care- ful examination of ETT prior to use. However, many defects remain unnoticed during routine inspection. This may lead to partial or complete airway obstruction of airway. Experience With a New Device for Clearing Mucus From From the Endotracheal Tube Robert H Stone RRT and Stephen S Bricknell RRT Partial or total obstruction of an endotracheal tube (ETT) by mucus can cause severe respiratory distress, hypoxemia, or death. Signs of an obstructed ETT include increased ventilation pressure, changesintheventilatorgraphics,S pO 2 Maneuvers To Relieve The Endotracheal Tube the distal bevel of the endotracheal tube had come into contact with the tracheal wall causing partial obstruction . Abutting of the endotracheal tube against the tracheal wall can also be a cause of ETT obstruction in prone ICU patients who are on long term ventilator support. The prone positioning of the patients like in our case
Several factors are responsible for endotracheal tube obstruction, for instance patients biting the ETT tube, kink-ing of ETT tube, accumulation of secretions and blood clots, airway tissues such as nasal turbinate, adenoids and foreign bodies . Biofilm formation caused by Abstract Endotracheal tube (ETT) obstruction, eitherAn Unusual Cause of Partial ETT Obstruction To the Editor:-Shearing of the plastic sheath of the stylet has been reported in the past with a 2.5-mm endotracheal tube (ETT) as a cause of complete ETT obstruction; we report a similar case of partial obstruction with a 3.0-mm ETT.
