What is the correct procedure for applying a nasopharyngeal airway (NPA)?

The proper procedure for applying a nasopharyngeal airway (NPA) involves several critical steps to ensure effective placement and minimize discomfort or injury. The correct procedure includes getting the device wet to facilitate smooth insertion, which helps reduce friction and trauma to the nasal passages.

Using the right nostril is preferred, as it is often easier to access and can help avoid potential complications with the left nasal passages, especially in cases where nasal injuries or deviations exist. Ensuring that the bevel of the NPA is oriented toward the septum aids in following the natural curvature of the nasal passages, allowing for a more comfortable and effective placement into the nasopharynx.

This procedure is particularly important because proper insertion technique can significantly reduce the risk of complications, such as mucosal damage or improper positioning of the airway, which could obstruct the airway instead of maintaining patency.
