In the [Oxygenation Calculation] window, you can:
 Change the pressure unit, Hb unit and oxygen content unit by selecting [Press. Unit], [Hb Unit] and [OxyCont
Unit] and then selecting the appropriate settings. The changes take effect automatically.
 Trigger a recording by selecting the [Record] button. The currently displayed oxygenation calculations are
printed out by the recorder.
 Review the previously performed calculations by selecting [Review].
