23.5 Oxygenation Calculations
The monitor provides the oxygenation calculation function. The monitor can save the results of up to 10
calculations, which are displayed in groups.
23.5.1 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 automat-
ically taken.
3. Select
Calculate
.
The calculated value greater than the normal upper limit is indicated by an up arrow “
↑
”. The 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.
