What is the correct order of steps in endotracheal intubation?

The correct order of steps in endotracheal intubation reflects a systematic approach to ensure the patient's safety and the effectiveness of the procedure. First, pre-oxygenation is a critical step that maximizes the patient's oxygen reserves before intubation, thereby reducing the risk of hypoxia during the process. Following pre-oxygenation, positioning the patient is essential to facilitate visualization of the airway; generally, this involves placing the patient in the sniffing position, which optimally aligns the oral, pharyngeal, and laryngeal axes.

Next is the use of laryngoscopy, where a laryngoscope is employed to visualize the vocal cords for tube insertion. This part of the procedure is crucial because effective visualization increases the chances of a successful intubation on the first attempt, minimizing trauma and distress for the patient. After visualization, inserting the endotracheal tube comes next; the tube should be carefully threaded through the vocal cords into the trachea. Finally, confirming placement of the tube is vital to ensure that it is correctly placed in the trachea and not in the esophagus, which can lead to serious complications if not identified.

This structured approach not only prioritizes the patient's airway and oxygenation but
