Q

What are the indications for use of an endotracheal tube?

A
  1. Inadequate arterial oxygenation, severe airway obstruction, shock and parenchymal diseases that impair gas exchange;
  2. upper airway obstruction;
  3. Impending gastric reflux or aspiration
  4. Provisions for tracheobronchial lavage and tracheal suctioning.

Q

What are the possible damages of the cuff of an endotracheal tube?

A
  1. The cuff’s structure and pressure can damage the tracheal mucosa, (erosin of mucosa) especially during long term care.
  2. Cuff inflation can damage vocal folds and resulting in inadequate ventilation.

Q

What is one of the risks assosiated with placing the ETT too high in the trachea?

A
  1. Inadvertent extubation
  2. Esophageal intubation: Air pumped into stomach resulting in regurgitation which then enters airway resulting on aspiration pneumonia.
