Respiratory failure & ventilation
The evaluation of a non-invasive respiratory monitor in ards patients in supine and prone position
Authors' conclusion
The RVM is accurate in assessing tidal volume and respiratory rate in prone compared to supine position.
Study context
- Population
- Sedated, paralysed, mechanically ventilated (volume-controlled) ARDS patients scheduled for prone positioning
- Participants
- 40 participants
- Exposure
- Respiratory volume monitor (RVM) measurements in supine vs prone position
- Outcome
- Accuracy of impedance-based non-invasive respiratory volume monitor (RVM) for tidal volume and respiratory rate
Main finding
As reported in the abstract
Tidal volume and respiratory rate, supine vs prone
Bias (limits of agreement)
0.12 bpm
CI −1.4 to 1.6
respiratory rate
Bias (limits of agreement)
20 mL
CI −80 to 120
tidal volume
- No significant difference supine vs prone for tidal volume
- P = 0.795; p = 0.302
- No significant difference supine vs prone for respiratory rate
- P = 0.181; p = 0.604
Observational data: associations, not effects.
