What device is typically established for an unconscious patient who cannot breathe independently?

The establishment of an endotracheal tube is the proper choice for an unconscious patient who cannot breathe independently because this device allows for the direct access of air into the trachea. In cases where the patient is unable to maintain their airway due to loss of consciousness, an endotracheal tube ensures that ventilation can occur effectively without the risk of aspiration.

An endotracheal tube is inserted through the mouth or nose and into the trachea, providing a secure airway for mechanical ventilation or assisted breathing, which is crucial for survival in the absence of spontaneous respiration. This device is particularly important in emergency situations where immediate airway management is required.

In contrast, while a ventilator is essential for mechanically helping a patient breathe, it relies on an airway being established first, which is why the endotracheal tube is the first step. Oxygen masks provide supplemental oxygen but do not secure the airway, making them unsuitable for unconscious patients who cannot breathe on their own. A CPAP machine is primarily used for patients with obstructive sleep apnea or those who need additional pressure during breathing but is also not designed for securing an airway in an unconscious individual.
