In which nostril are most NPAs designed to be placed?

Most nasopharyngeal airways (NPAs) are designed to be placed in the right nostril due to anatomical considerations. The majority of individuals have a more favorable angle and larger passage in the right nostril, making it easier to insert the NPA. The curvature and anatomy of the nasal passages allow for a smoother insertion when using the right nostril, helping to ensure proper placement and function of the airway device.

In practical application and training, this preference is often reinforced, as healthcare providers typically follow this guideline for efficiency and effectiveness in emergency airway management. While NPAs can be inserted into either nostril, the preference for the right nostril emerges from the anatomical architecture and is emphasized to enhance successful airway management in clinical scenarios.
