Which intervention can increase intrabolus pressure while swallowing?

The effortful swallow maneuver is designed specifically to increase intrabolus pressure during swallowing, which enhances the efficiency of the swallow and can help prevent aspiration. By encouraging individuals to exert more effort in their swallowing process, this technique aids in creating a greater pressure within the bolus, thereby facilitating its movement through the esophagus and reducing the risk of a residue remaining in the throat or entering the airway.

The other interventions may have different focuses or outcomes. For example, the Mendelsohn maneuver is primarily aimed at prolonging the swallow duration and improving coordination but doesn't specifically target intrabolus pressure the same way the effortful swallow does. The tongue tether maneuver focuses on stabilizing the tongue, and while it may indirectly affect pressure, it isn’t aimed specifically at enhancing intrabolus pressure. The breath-holding with Valsalva maneuver is primarily used in other contexts, such as increasing the pressure in the thoracic cavity, and does not directly impact the swallowing process in the same targeted manner as the effortful swallow maneuver.

Overall, the effortful swallow maneuver is the most appropriate choice for increasing intrabolus pressure during swallowing due to its design and intended outcomes.
