Endotracheal intubation is a technique used to treat difficult airways, ensure air circulation of breaths, clear airways and avoid complications. Endotracheal intubation is a difficult technique, requiring highly skilled equipment and doctors, minimizing risks.

Intubation techniques in adults help patients maintain an airway due to trauma, disease or infection that causes acute airway obstruction. This is a difficult technique, but very important in emergency patient resuscitation.

Difficult intubation is when the intubation time is longer than 10 minutes or requires more than three attempts. If not treated promptly, difficult intubation can cause dangerous complications such as severe hypoxia and cardiovascular collapse, leading to cardiac arrest, cerebral ischemia, and death. Below is a flow chart for difficult intubation.
