|Copyright © Nucleus Medical Media, Inc.|
Reasons for Procedure
- Damage to teeth, lips, or tongue
- Damage to the trachea or larynx resulting in pain, hoarseness, or difficulty breathing after the tube is removed
- Esophageal intubation—when the tube is accidentally inserted into the esophagus and stomach rather than the trachea
- Low blood pressure
- Too little or too much ventilation
- Lung injury/collasped lung
- Neck or cervical spine injury
- Pre-existing lung disease such as emphysema
- Poor condition of teeth
- Recent meal
- Diseases that cause muscle weakness such as myasthenia gravis
What to Expect
Prior to Procedure
- The night before, eat a light meal. Do not eat or drink anything after midnight.
- Ask your doctor about any other special directions.
Description of the Procedure
Immediately After Procedure
- Listen to your lungs to make sure that the air is going into them equally
- Do a chest x-ray to make sure the tip of the tube is positioned in the middle of your trachea
- Measure the level of gases in your blood to make sure that the ventilation is working
