Final answer:
An advanced airway is inserted when basic airway maneuvers fail to maintain a clear and open airway for the patient. This is typically done by healthcare professionals.
Step-by-step explanation:
In medical emergencies, an advanced airway is typically inserted when basic airway maneuvers fail to maintain a clear and open airway for the patient. This usually occurs when the patient is unable to breathe properly or is at risk of losing their airway due to an underlying condition or injury.
It is important to note that inserting an advanced airway should only be done by a trained healthcare professional or paramedic, as it involves more invasive techniques such as endotracheal intubation or supraglottic airway devices.
