Final answer:
When an ET tube is properly positioned, it is inserted into the trachea, secured in place, and the patient's oxygen and carbon dioxide levels are stable.
Step-by-step explanation:
When an ET tube (endotracheal tube) is properly positioned, the following expected findings can be observed:
- The tube is inserted into the trachea and not the esophagus. It should be secured in place and not have any movement.
- The patient's oxygen levels and carbon dioxide levels are stable.
- There are bilateral breath sounds heard on auscultation of the chest.
