Changing or
Entering an
Input Value
The arrow keys are used to select a parameter and the keypad is used to
enter or change the selected value. With a touchscreen, you can select a
parameter by selecting the touch button in front of the parameter label. A
numeric touchboard will be included in the task window to enter or
change values.
If you enter a value that has more decimal places than allowed for a
particular input, the value you enter will be rounded off after you press
. Numbers 1 to 4 will round the value down and numbers 5 to 9
will round the value up. For example, if you enter 6.55 as an input for a
value where only one decimal place is allowed, 6.6 will be the value used
in the calculation and displayed. If you enter 6.54, 6.5 will be used in the
calculation and displayed.
If you enter a value which cannot be stored, the message Parameter value
input range X: “Y OUT OF RANGE” will appear. The value for X will be
either the upper limit (if the value entered is greater than the upper limit)
or the lower limit (if the value entered is less than the lower limit). Y is
the value you entered. Enter a new value.
Reviewing
Calculations
The Hemodynamics, Ventilation, and Oxygenation Review displays enable
you to review all calculations made in these groups within the last 24
hours (48 hours if a memory extension is purchased and configured).
Calculated parameter values (both indexed and non-indexed) are
presented with the values used to calculate them. The calculation times
are indicated along the top of the display. The normal ranges for the
parameters can also be shown.
Additional calculation or input values are available by using the
key. To select another time column, either use the arrow
keys or the
softkey.
