Step-by-step explanation:
In the absence of trauma, secretions, foreign bodies, and edema, basic manual airway maneuvers should always be used. Basic manual airway maneuvers are techniques that can be used to help clear the airway and ensure that the person is able to breathe properly. These maneuvers include techniques like the Heimlich maneuver, which can be used to force an aspirated object out of the respiratory tract.
By using these maneuvers, it helps to ensure that the airway remains open and clear, allowing the person to breathe effectively.
