Which adjunct devices can be used during the bag-valve-mask ventilation to improve sealing?

The use of adjunct devices during bag-valve-mask (BVM) ventilation is critical for improving the seal and ensuring effective ventilation, especially in patients with challenging airway anatomies. The correct choice of adjunct devices includes a dual-lumen airway device or a laryngeal mask airway.

Both the dual-lumen airway device and the laryngeal mask airway are designed to create a proper seal in the airway, allowing for more effective transport of air into the lungs. The laryngeal mask airway, in particular, sits above the trachea and forms a seal around the laryngeal inlet, minimizing air leakage during ventilation. Similarly, dual-lumen devices can also provide a secure positioning within the airway, facilitating better oxygenation and ventilation.

These adjuncts offer advantages when direct visualization of the airway is difficult or when traditional methods of securing the airway may fail. With a better seal achieved through these devices, healthcare providers can deliver adequate tidal volumes effectively, which is essential during emergencies, particularly in patients who might exhibit features of airway obstruction or inflammation.

In contrast, options such as an endotracheal tube or an oropharyngeal airway are important airway management tools but do not directly improve the seal during BVM
