Which nare is the NPA specifically designed to be inserted into?

The NPA, or Nasopharyngeal Airway, is specifically designed for insertion into one particular nare based on the anatomy and the preference for right vs. left-handed procedures. The design typically accommodates the natural curvature of the nasal passages, which may favor insertion into the right nare for many practitioners. The anatomical position, ease of access, and reduced likelihood of trauma to the nasal structures are some of the reasons why insertion is often oriented this way.

However, it's important to note that while a specific nare is preferred for insertion, NPAs can technically be inserted into either nare, and the choice may sometimes depend on individual patient anatomy or the practitioner’s preference during an emergency. The other options suggest a more broad or flexible approach, which while applicable in certain circumstances, does not align with the training emphasis on the preferred single nare method as indicated in the question.

Understanding the rationale behind the selection of the right nare can assist paramedics in minimizing complications and maximizing the effectiveness of airway management.
