(First published 24.08.17) Removal of recommendation to adjust patient height to compensate for additional dead space. A logical starting point is setting a %MinVol value that will result in the same minute volume as a previous mode, if applicable.
For example, the %MinVol could be set as follows:
Add 20% if the body temperature exceeds 38.5°C (101.3°F) and 5% per 500 m (1640 ft) above sea level.
In the table shown here below the clinical workflow, you can see recommendations regarding %MinVol changes for various clinical conditions. For more information on adjustment of %MinVol in ASV mode, see your Hamilton Medical ventilator’s Operator’s Manual.
| Condition | %MinVol change | Remarks |
| Normal arterial bloodgas | None | -- |
| High PaCO2 | Increase %MinVol | Pay attention to inspiratory pressures |
| Low PaCO2 | Decrease %MinVol | Pay attention to mean airway pressure and oxygenation status |
| High respiratory drive | Consider increasing %MinVol | Consider sedation, analgesia or other treatments |
| Low Oxygen saturation | None | Consider increasing PEEP and/or Oxygen |
