One of the primary benefits of an ETT is that it helps maintain the patency of the airway. This is particularly important in patients who are unconscious, sedated, or have suffered a trauma. Without an open airway, these patients cannot breathe and can suffer from hypoxia (low oxygen levels), which can lead to brain damage or death. Endotracheal Tube are also used to provide mechanical ventilation, which is a lifesaving therapy that assists with breathing.
Mechanical ventilation can be used to support patients with respiratory failure, acute lung injury, or other conditions that prevent them from breathing on their own. The ETT is connected to a mechanical ventilator, which delivers air into the lungs and helps remove carbon dioxide. ETTs can also be used to administer medications directly into the lungs. This is particularly useful in patients with severe respiratory distress, where medications need to be delivered quickly and directly to the site of action. Medications such as bronchodilators, steroids, and antibiotics can be given through the ETT.
