17.5 Oxygenation Calculations
The monitor provides the oxygenation calculation function and can save the results of up to 10 calculations,
which are displayed in groups.
17.5.1 Performing Oxygenation Calculations
To perform oxygenation calculations, follow this procedure:
1. Access oxygenation calculation by either of the following ways:
◆ Select the Calculations quick key → Oxygenation tab.
◆ Select the Main Menu quick key → from the Calculations column select Oxygenation.
2. Enter the known values. For a patient who is being monitored, the currently measured values are
automatically entered.
3. Select
Calculate.
A calculated value greater than the normal upper limit is indicated by an up arrow “
↑”. A calculated value
lower than the normal lower limit is indicated by a down arrow “
↓”.
In the
Oxygenation page, you can also perform the following operations:
■ Select Oxycont Unit, Hb Unit, and Pressure Unit. Then corresponding parameter values will be
automatically converted and updated accordingly.
■ Select Range to show the normal range of each parameter.
