- High PEEP (15 cm H2O) improves V/Q mismatch in ARDS patients with high lung recruitability (R/I ratio ≥0.60) in both supine and prone positions.
- In patients with lower recruitability (R/I ratio <0.60), high PEEP worsens V/Q mismatch in prone position but has no significant effect in supine position.
- The study used Recruitment-to-Inflation (R/I) ratio to assess lung recruitability and measured V/Q mismatch at different PEEP levels in 50 moderate-to-severe ARDS patients.
- Findings suggest PEEP optimization should consider both patient position and lung recruitability to improve oxygenation in ARDS.
