Choosing graphic displays
During blood parameter measurement in the “operate” mode, the CDI System 550 can
display the patient’s blood gas parameter values in a graphical format. The graph will
show blood parameter values over two selectable time periods, so you can see changes
in a patient’s blood parameters at a glance.
The third screen in setup mode — the graphic display screen — allows you to choose
which parameter values to display in the graphical format. You can specify up to six
groups of three parameters for graphic display — three graphs, each displaying values for
one parameter, can be displayed at one time.
On the graphic display setup screen, here’s how you use the selection and edit keys:
1 Press the and keys to select a group.
2 Press edit.
3 Use the and keys to highlight a particular item within the selected group.
4 Use the + and − or and keys to change the entry for the selected item.
The possible entries are listed in the next table.
Note: Any group can have one or more parameter(s) disabled. Only if all three are
disabled will the group be skipped over in graphics display. If a group has one or two dis-
abled parameters, that one or two will show up as a blank graph in the graphics display.
5 After you’ve selected all three items for a group, press √.
