Using NIV in Patients with Tracheostomy
Yes, a person with a tracheostomy can use non-invasive ventilation (NIV), and in some clinical scenarios, this approach may be preferable to conventional invasive mechanical ventilation through the tracheostomy. 1
Clinical Applications
Scenarios Where NIV Can Be Used with Tracheostomy
During Weaning Process
- NIV can be used in patients with tracheostomy during the weaning process, either:
- Directly connected to the tracheostomy tube
- Via mask after capping the tracheostomy tube 1
- NIV can be used in patients with tracheostomy during the weaning process, either:
Long-term Home Mechanical Ventilation
Post-Extubation Support
- In patients with COPD and neuromuscular disorders
- BTS guidelines recommend NIV-supported extubation in preference to inserting a tracheostomy 3
Advantages of NIV with Tracheostomy
- Portability: NIV devices are typically more portable than conventional ventilators
- Ease of operation: Simpler to use and maintain
- Cost-effective: Lower cost compared to conventional ventilators
- Potential for improved communication: May allow better speech capabilities depending on setup 1
Patient Selection
Good Candidates
- Patients with neuromuscular diseases (e.g., Duchenne muscular dystrophy)
- Patients with chronic obstructive pulmonary disease (COPD)
- Patients in the process of weaning from mechanical ventilation 1, 4
Cautions and Considerations
- Secretion Management: Patients with excessive secretions may require additional airway clearance techniques
- Monitoring Requirements: Regular monitoring of gas exchange is essential, including:
- Oxygen saturation
- End-tidal CO2 levels (at least annually) 3
- Arterial blood gas analysis when indicated
Implementation Approaches
Two Main Methods
Direct Connection to Tracheostomy
- NIV device connected directly to the tracheostomy tube
- Useful for patients who still need the tracheostomy for secretion management
Mask Ventilation with Capped Tracheostomy
- Tracheostomy tube is capped
- NIV provided via mask interface
- Can be a step toward potential decannulation 1
Evidence and Outcomes
Research has shown positive outcomes for using NIV in patients with tracheostomy:
- In one study of 72 cases using NIV via tracheostomy tube, 33 patients were successfully weaned and 24 continued with home mechanical ventilation 1
- In another study of 288 cases using mask ventilation with capped tracheostomy, successful decannulation was achieved in 254 patients 1
- A study of patients with Duchenne muscular dystrophy showed that 24-hour NIV (including daytime mouthpiece ventilation) could be a safe alternative to tracheostomy ventilation 5
Clinical Pitfalls to Avoid
- Inadequate Monitoring: Ensure regular monitoring of oxygen saturation to detect mucus plugs 3
- Ignoring Patient Comfort: Select appropriate interfaces and ventilator settings to ensure patient tolerance
- Overlooking Secretion Management: Patients with tracheostomy often have increased secretions that require management
- Failure to Have Backup Plans: Always have contingency plans for equipment failure or clinical deterioration
Conclusion
NIV can be successfully used in patients with tracheostomy in various clinical scenarios, particularly during weaning and for long-term ventilation in selected patients. The decision should be based on patient-specific factors including underlying diagnosis, secretion management needs, and overall clinical status.
