VI. Technique
- Lubricate with water soluble lubricant (or Anesthetic jelly)
- Gently insert into nostril
- Leading edge of bevel should be away from septum (away from Kiesselbach's Plexus)
- If results in upside-down Nasal Trumpet, rotate 180 degrees after passing the anterior nare
- Insert along floor of nostril, perpendicular to face
- If resistance occurs
- Try slight tube rotation
- Try other nostril
- Leading edge of bevel should be away from septum (away from Kiesselbach's Plexus)
- Check for respirations following placement
