The Closed Suction System is a vital tool in medical settings for effectively suctioning sputum or secretions from patients' respiratory tracts. This system maintains a closed environment, minimizing the risk of cross-infection. It consists of suction catheters, suction machines, and closed tubing and containers that prevent sputum leakage during the suctioning process.

1. Gather equipment: suction system, machine, and sterile gloves.
2. Verify the suction machine is functional.
3. Inspect components for damage or contamination.
4. Evaluate child's respiratory status and tolerance.
5. Determine suctioning necessity based on distress or secretions.
6. Position child comfortably (supine or head elevated).
7. Ensure airway is clear and accessible.
8. Wear sterile gloves and maintain a sterile field.
9. Cleanse airway with sterile saline or water.
10. Connect catheter securely to the suction machine.
11. Adjust pressure to pediatric recommended levels.
12. Lubricate catheter with sterile saline.
13. Insert catheter to appropriate depth per instructions.
14. Apply suction while withdrawing slowly and gently.
15. Stop immediately if child shows discomfort.
16. Turn off machine and withdraw catheter.
17. Monitor child for changes in status.

• Do not reuse; do not use expired products.
• Use only under directed nursing staff supervision.
• Maintain strict sterile technique throughout.
• Avoid excessive suctioning to prevent airway trauma.
• Disposal: Dispose in sanitary containers to prevent cross-infection.
• Storage: Store in dark, dry, and clean conditions away from harmful substances.
