Transtracheal Oxygen Therapy: Procedure, Care & Weaning

Transtracheal oxygen delivery involves surgically placing a small catheter directly into the trachea via a neck stoma, bypassing the upper airway.

Process

1. Evaluation: Pulmonary function, airway anatomy, psychosocial readiness.
2. Surgery: Under local/general anesthesia; catheter secured with sutures/foam.
3. Delivery: Humidified O₂ via portable system; flow titrated to saturation.
4. Monitoring: ICU/step-down initially; O₂ sat, secretion management, stoma care.
5. Rehabilitation: Patient/caregiver training (cleaning, suctioning, troubleshooting).
6. Weaning: Gradual reduction as lung function improves.
7. Decannulation: Stoma closes spontaneously after tube removal.

Indicated for severe chronic hypoxemia unresponsive to conventional O₂, or upper airway obstruction. Improves mobility, compliance, quality of life.
