Can the Trilogy Ventilator Be Used for Invasive Ventilation Through a Tracheostomy?

Yes, the Trilogy ventilator can be used for invasive ventilation through a tracheostomy. The device is a portable home ventilator that has been successfully utilized for positive pressure ventilation via tracheostomy (PPV-T) in both pediatric and adult populations requiring long-term mechanical ventilation 1.

Evidence Supporting Trilogy Use for Tracheostomy Ventilation

The most direct evidence comes from a 2022 pediatric study documenting that Trilogy 100 and 200 ventilators are routinely utilized in children using home positive pressure ventilation via tracheostomy 1. This study involved 40 children using PPV-T with Trilogy ventilators, confirming its established role as a portable home ventilator (PHV) for invasive ventilation.

Clinical Context and Indications

When Tracheostomy Ventilation Is Appropriate

Invasive mechanical ventilation via tracheostomy should be considered in specific clinical scenarios 2:

  • When noninvasive ventilation fails or is contraindicated
  • Severe bulbar weakness or dysfunction preventing effective NIV use
  • Lack of sufficient oromotor and/or neck control for mouthpiece interfaces
  • Need for higher ventilator pressures in patients with intrinsic lung disease or severe chest wall compliance reductions (e.g., severe scoliosis)
  • Requirement for direct airway suctioning during respiratory infections
  • Patient preference after appropriate education

Advantages of Tracheostomy Ventilation

The guidelines emphasize several benefits 2:

  • More secure ventilator-patient interface
  • Ability to deliver higher pressures when needed
  • Direct airway access for suctioning
  • Facilitates weaning from prolonged ventilation when primary extubation has failed or is likely to fail

Important Caveats and Complications

Risks to Monitor

Tracheostomy ventilation carries significant complications that require vigilance 2:

  • Increased secretion production
  • Impaired swallowing with increased aspiration risk
  • Bypassed airway defenses leading to higher infection risk
  • Risk of airway occlusion by mucus plugs (requires pulse oximetry monitoring)
  • Communication impairment (though speaking valves can help with leaky systems)
  • Cosmetic concerns

Ventilator Settings Considerations

When using any ventilator (including Trilogy) with tracheostomy 2:

  • Compensate for leaks by increasing tidal volume when using smaller tracheostomy tubes with speaking valves
  • Ensure adequate humidification to prevent mucus plugging
  • Regular monitoring of gas exchange with pulse oximetry and end-tidal CO2 when available
  • Individualize settings based on patient comfort, sleep quality, and secretion management

Practical Implementation

Home Mechanical Ventilation Setup

For successful home invasive mechanical ventilation 3:

  • Requires medical stability before discharge
  • Needs suitable home environment
  • Demands adequate caregiver support and training
  • Requires community healthcare support infrastructure
  • Necessitates equipment availability and maintenance
  • Must include end-of-life decision documentation

Transition Protocol

Based on the pediatric experience with Trilogy ventilators 1:

  • Systematic protocol collaborating with patients, physicians, and durable medical equipment companies optimizes transitions
  • Median hospitalization duration for ventilator changes is approximately 2 days (1 day for elective changes)
  • Inpatient ventilator changes allow for safe parameter adjustment and monitoring

Alternative Considerations

Before proceeding to tracheostomy ventilation, the guidelines strongly recommend attempting 2, 4:

  1. Noninvasive ventilation first (BPAP, mouthpiece ventilation)
  2. Optimize NIV parameters through assessment of patient comfort, sleep quality, and gas exchange
  3. Consider mouthpiece ventilation for daytime support in appropriate candidates

Only proceed to tracheostomy when NIV is inadequate, not tolerated, or contraindicated due to bulbar dysfunction, inability to protect airway, or patient preference after thorough education 2.

Bottom Line

The Trilogy ventilator is an established portable home ventilator suitable for invasive ventilation through tracheostomy 1. However, tracheostomy should be reserved for patients who cannot be managed with noninvasive ventilation due to the significant burden of care, complications, and impact on quality of life 2. Patient autonomy must be respected after comprehensive education about both the benefits and substantial burdens of long-term invasive ventilation 2.
