Regulation of Intracuff Pressure by Measurement of the Ratio of Expiratory to Inspiratory Tidal Volumes
Authors' conclusion
Adjustment of the TVe/TVi may be a more effective means of ensuring that the cuff pressure is in the desired range than other conventionally used clinical techniques such as sealing the airway to a CPAP of 20 cmH2O.
Study context
- Population
- Pediatric patients presenting for GA with an endotracheal tube (ETT)median age 12 years
- Participants
- 50 patients
- Exposure
- Cuff inflation by continuous positive airway pressure (CPAP) seal vs tidal volume (TVe)/TVi ratio 1.0, 0.9 and 0.8
- Outcome
- Intracuff pressure
Methodological detailscross-over
- Cross-over
Main finding
As reported in the abstract
Observational data: associations, not effects.
Safety
- Cuff pressures >30 cmH2O — CPAP
- 10 events
- Cuff pressures >30 cmH2O: TVe/TVi 1 2 events
Cuff pressures >30 cmH2O
- No cuff pressures >30 cmH2O with a TVe/TVi ratio of 0.9 or 0.8
