The respiratory calculations provide calculations based upon patient demographic information provided in the fields above. Some calculations require additional patient data, for which fields are provided within the calculation. As with all clinical decision support tools, ultimately use clinical judgement when considering these results.
- Some calculations may have important additional information which can be shown using the question mark icon

- Calculated using ideal body weight
- Low tidal volume uses 6-8 mL/kg1
- Current evidence does not show benefit of intraoperative low tidal volumes for patients without pulmonary injury2
