Suction Catheter Selection Guide: Size, Tip, Material, Length & Safety Features

Step-by-Step Selection

1. Assess patient – Age, condition, secretion type.
2. Determine size (French)
   • Adults: 14–18 Fr
   • Children: 8–12 Fr
   • Infants/neonates: 5–8 Fr
3. Choose tip configuration
   • Round tip – general purpose.
   • Angled (coudé) tip – difficult anatomy.
   • Beveled tip – thicker secretions.
4. Material
   • PVC – common, lightweight, flexible.
   • Polyurethane – softer, less traumatic for long-term use.
   • Silicone elastomer – softest, for sensitive areas/extended intubation.
5. Suction control – Valve/port to regulate suction strength.
6. Length – 15–30 cm standard; longer for deep suctioning.
7. Sterility – Always use sterile catheters.
8. Single-use vs. reusable – Follow manufacturer guidelines.
9. Additional features – Atraumatic tips, depth markings, hydrophilic coatings.
10. Consult a professional if uncertain.
11. Prioritize patient comfort/safety – Minimize trauma, use gentle technique.
