Final answer:
To correctly size the NPA (nasopharyngeal airway), start by selecting the appropriate size based on the distance from the patient's nares to the tragus of the ear. Lubricate the NPA and gently insert it into the nostril, ensuring correct positioning by checking for equal airflow. Secure the NPA in place and consider using a smaller size if needed.
Step-by-step explanation:
How to Correctly Size the NPA (Nasopharyngeal Airway)
- Start by selecting the appropriate size NPA. This can be determined by measuring the distance from the patient's nares to the tragus of the ear, which is the external opening of the ear. The selected size should be approximately two-thirds of this distance.
- Lubricate the NPA with a water-based lubricant.
- Gently insert the NPA into the nostril of the patient. The bevel tip should be pointing upwards, following the curve of the nasal passage.
- Continue inserting until the flange or flared end of the NPA is touching the patient's nostril.
- Ensure that the NPA is correctly positioned by checking for equal airflow through both nostrils.
- Secure the NPA in place with tape or by attaching it to the patient's cheek with a safety pin.
Remember to always follow proper infection control procedures and consider using a smaller-sized NPA if the patient experiences discomfort or resistance during insertion.
