Changes in the tissue oxygenation index (TOI). (a) indicates the right TOI values: 76.0% (66.4–79.7) just before sedation (baseline value), 74.5% (66.9–79.5) when OAA/S score of 2 was achieved after midazolam administration, and 73.6% (65–79.6) just before the start of treatment in the dementia-negative group; 71.8% (66.4–74.4) just before sedation (baseline value), 71.8% (66.9–74.5) when OAA/S score of 2 was achieved after midazolam administration, and 71.0% (67.8–74.6) just before the start of treatment in the dementia-positive group. (b) indicates the left TOI values: 76.2% (67.1–80.9) just before sedation (baseline value), 75.1% (70.7–80.9) when OAA/S score of 2 was achieved after midazolam administration, and 74.8% (68.6–79.5) just before the start of treatment in the dementia-negative group; 75.3% (71.2–77.3) just before sedation (baseline value), 74.5% (72.4–78.2) when OAA/S score of 2 was achieved after midazolam administration, and 75.5% (74.4–80.6) just before the start of treatment in the dementia-positive group.
