What scenario requires the use of an Endotracheal Tube?

The use of an Endotracheal Tube (ET tube) is specifically indicated for patients who require emergency airway management. This involves situations where the patient's airway is compromised or at risk of becoming obstructed, making it essential to secure the airway promptly for adequate ventilation and oxygenation. Examples may include severe respiratory failure, unresponsiveness, or trauma that affects breathing ability.

In contrast, patients who are breathing spontaneously may not need an ET tube if they do not have any signs of airway obstruction or significant respiratory distress. Similarly, mild respiratory distress generally does not warrant urgent intervention with intubation, as these patients may still be able to maintain their airway and oxygen levels with less invasive support, such as supplemental oxygen or non-invasive positive pressure ventilation. Lastly, patients requiring only supplemental oxygen usually do not need an ET tube, as their airway remains intact and they are capable of maintaining their respiratory function without invasive measures.
