This randomized controlled trial evaluated an electrical impedance tomography (EIT)-guided pulmonary rehabilitation strategy in 92 ICU patients with respiratory failure at a tertiary hospital; 88 completed the study. Compared with conventional pulmonary physical therapy, the EIT-guided group received additional positioning, vibratory sputum clearance, and early mobilization. The intervention group had greater dorsal ventilation share on days 2 and 3, higher PaO₂/FiO₂, shorter ICU stay (6.55 vs. 7.75 days), and lower delirium incidence (25.0% vs. 45.5%). Respiratory rate and oxygen saturation improved over time in both groups, without significant between-group effects.
Key findings
- Dorsal ventilation share was higher with EIT guidance on days 2 and 3, but not significantly different on day 1.
- ICU stay was 6.55 vs. 7.75 days in the experimental and control groups, respectively.
- Delirium incidence was 25.0% vs. 45.5% in the experimental and control groups, respectively.
- PaO₂/FiO₂ was higher in the experimental group; respiratory rate and pulse oxygen saturation showed no significant group or interaction effects.
Why it matters
The findings suggest that using EIT to guide positioning and rehabilitation may help target regional ventilation and may be associated with better oxygenation and ICU outcomes in respiratory failure. The absence of between-group effects for respiratory rate and oxygen saturation indicates that benefits were not uniform across measured respiratory outcomes.
What to keep in mind
The study was conducted at a single tertiary hospital, and 88 of 92 randomized patients completed it. Follow-up assessments were limited to the following three days for several respiratory measures.
