Respiratory failure & ventilation
Reverse triggering ? a novel or previously missed phenomenon?
Authors' conclusion
RT has been present in the literature as early as 1997, but most cases were found after the introduction of low tidal volume ventilation in 2000. Following 2013, the number of undetected cases decreased, but RT are still commonly missed.
Study context
- Population
- Published figures with ventilator waveforms expected to display reverse triggering if present, PubMed, EMBASE and Cochrane Central, 1950 to 2017waveforms in 65 papers
- Participants
- 181 participants
- Comparison
- Waveforms published before vs after 2000
- Outcome
- Frequency of undetected reverse triggering (RT) in published waveforms
Methodological detailsexpert waveform labelling
- Expert waveform labelling
Pooled result
As reported in the abstract
RT identified by experts
- 'Possible' reverse triggering (RT) cases
- 21
- 'Definite' RT cases
- 25
- Waveforms prior to 2013 with evidence of RT
- 18.8%
- RT cases attributed to different phenomena
- 54%
- Cases published before vs after 2000
- 1 before vs. 45 after, p = 0.03
Further pooled results
- RT cases attributed to different phenomena decreased after 2013; 'possible' RT remained missed
- 60%
- Earliest RT case described under different terminology
- 1997
