Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Level0 Alert and calm

→RASS0

  • Target：Most ventilated patients are targeted to 0 to −2 (light sedation) unless deeper sedation is indicated.
Level+4 Combative

→RASS+4

  • Target：Most ventilated patients are targeted to 0 to −2 (light sedation) unless deeper sedation is indicated.
