What are supraglottic devices designed to do?

Supraglottic devices are specifically designed to create a seal around the glottic inlet, which is the opening to the larynx. This is crucial in airway management, especially in situations where traditional intubation might be difficult or impossible. By sealing around the glottic inlet, these devices ensure that air can be effectively ventilated into the lungs while preventing the aspiration of gastric contents, enhancing patient safety and airway patency.

These devices are often used in emergency scenarios because they provide a relatively quick and effective means of securing an airway without the need for full tracheal intubation. This is particularly valuable in tactical environments where time is of the essence, and the need for effective ventilation is critical.

In contrast, the other options either suggest incorrect functions or functions that are not applicable to supraglottic devices. Secure intubation into the trachea is more specific to endotracheal tubes. Facilitating nasopharyngeal access does not directly pertain to the role of supraglottic devices, as their primary function is not about accessing the nasal passages but rather providing a direct pathway to the airway above the vocal cords. Measuring airway pressure is typically outside the intended use of supraglottic
