Respiratory failure & ventilation
High‐flow via a tracheostomy tube and speaking valve during weaning from mechanical ventilation and tracheostomy
Authors' conclusion
Current study clinical data and benchtop experiments indicate that HFT-T-OWV was well tolerated and appeared safe.
Study context
- Population
- Tracheostomized patients undergoing weaning attempts at an intensive care rehabilitation center, 2019–2022124 treated with HFT-T-OWV
- Participants
- 128 patients
- Outcome
- Adverse events of HFT-T-OWV
Methodological detailssingle-centre, quality register, benchtop simulation

Observational data: associations, not effects.
Further findings
Main reason for not using HFT-T-OWV
- Partial upper airway obstruction using a one-way valve (OWV)
Benchtop: HFT-T-OWV maximum pressure and pressure support (25-60 L/min flow)
- Maximum pressures
- <4 cmH2 O
- Pressure support
- 0-0.6 cmH2 O
Benchtop: standard OWV with 1-3 L/min supplemental oxygen, simulated airway obstruction
- Pressures
- between 84 and 148 cmH2 O
