Final answer:
Inserting an NPA involves measuring for a properly sized NPA, lubricating it, and gently inserting it with a twisting motion, ensuring the bevel faces the septum. Correct sizing and consideration of contraindications are essential for safe insertion.
Step-by-step explanation:
To properly insert a Nasopharyngeal Airway (NPA), you must first select an appropriate size. Measure from the patient's nostril to the tip of their earlobe or angle of the jaw. This measurement corresponds to the proper length of the NPA. As for the diameter, it should be approximately the same as the patient's pinky finger. The correct technique involves lubricating the NPA with water-soluble jelly. Then, insert it into the nostril with a gentle twisting motion, following the floor of the nasal cavity to avoid trauma. The bevel should face the septum to prevent complications. Once in place, the NPA should allow for clear air passage without causing pain or damage to the nasal tissues.
When selecting an NPA, it is critical to ensure that it is neither too long nor too wide to avoid injury. It's also important to consider contraindications, such as suspected nasal fractures or coagulopathies. The patient's level of consciousness and gag reflex are also key considerations, as an NPA is better suited for individuals who are semi-conscious or unconscious with an intact gag reflex. Always ensure proper sterilization and follow the protocols specific to your medical setting.
