[Calculations] QuickKey[Hemodynamic >>].
2. Enter values for calculation.
 For a patient who is being monitored, [HR], [Art mean], [PA mean] and [CVP]
are automatically taken from the currently measured values. If you just have
performed C.O. measurements, [C.O.] is the average of multiple thermodilution
measurements. [Height] and [Weight] are the patient’s height and weight you
have entered. If the monitor does not provide these values, their fields appear
blank.
 For a patient who is not being monitored, confirm the values you have entered.
3. Select the [Calculate] button. The system performs a calculation per the current
settings and displays the calculated values.
 If a calculated value is outside the range, its background will highlight in yellow.
You can select [Range] to view its normal range in the unit field.
 Invalid values are displayed as [---].
In the [Hemodynamic Calculation] window, you can:
 Trigger a recording by selecting the [Record] button. The currently displayed
hemodynamic calculation is printed out by the recorder.
 Review the previously performed calculations by selecting [Review].
