What is the procedure for endotracheal intubation?

The procedure for endotracheal intubation involves the placement of a tube directly into the trachea, which serves to establish an airway. This is a critical intervention, particularly in medical emergencies or when a patient is unable to breathe adequately on their own. The endotracheal tube provides a clear passage for air to enter the lungs and enables mechanical ventilation if required.

The correct procedure requires careful technique to avoid damaging surrounding tissues and to ensure proper positioning of the tube. Typically, intubation is performed when a patient has compromised airways due to various reasons, such as severe obstruction, respiratory failure, or during surgical procedures that require general anesthesia.

Other options describe different procedures. For instance, inserting a tube through the mouth into the stomach pertains to gastric intubation, which is not related to airway management. Connecting a non-invasive mask to deliver oxygen describes supplemental oxygen therapy rather than a procedure used to secure an airway. Lastly, placing an airway device in the nasal cavity (nasal intubation) is a different approach and not what is designated by endotracheal intubation, which specifically refers to the trachea.
