Respiratory failure & ventilation
Non-invasive over-distension measurements: data driven vs model-based
Authors' conclusion
The proposed OD offers an efficient, general, real-time measurement of patient-specific lung mechanics, which is more intuitive and robust than SI.
Study context
- Population
- Acute respiratory distress syndrome (ARDS) patients on mechanical ventilation (MV)196 cases
- Participants
- 19 patients
- Comparison
- Non-invasive over-distension measurement vs stress index
- Outcome
- Correlation between OD and SI (R2 and Spearman rs)
Main finding
As reported in the abstract
Overall correlation between OD and SI
R2
0.76
Spearman rs
0.89
Further findings
Correlation by ARDS severity (subgroup)
- Correlation higher considering only moderate and severe ARDS patients
OD safe range calibrated to stress index (SI) safe range (0.95-1.05)
- OD safe range
- 0 ≤ OD ≤ 0.8 cmH2O
- Calibrated by sensitivity and specificity test
