21 Guardian Early Warning Scoring
303
One complete set of vitals and observations, together with the calculated score(s), is referred to as
a SpotCheck record. Once all the required vitals have been entered or measured, the SpotCheck
record will be automatically stored after the configured freeze time.
If you want to store values before the end of the freeze time, you can select
Store Vitals, to store
the values and close data collection. The
Store Vitals key can also be used to store an incomplete
set of vitals at any time.
If you want to break off the Early Warning Scoring process without storing the SpotCheck record,
use the
Clear VS key.
4 To leave the EWS procedure and return to your standard monitoring screen, select the appropriate
screen from the screen list, or select the
Previous Screen SmartKey (if configured).
WARNING
Alarms: There will be no alarm indications for measurements in the entry screen.
Values: The values shown in the entry screen do not have the same annotation as the measurement
values on other monitor screens. There is no special indication when a value has been manually
entered and no timestamp showing when the value was measured/entered. Be aware that values will
remain visible until the freeze time is at an end, even when the measurement itself is no longer
providing current values.
Understanding Guardian Early Warning Scoring
An early warning score is an assessment aid used to help recognize the early signs of deterioration in
medical patients. There are two basic types of scoring:
• Single Parameter Scoring (SPS) - A score is given for each of the vitals based on the measured/
entered value. Each vital sign has upper and lower thresholds assigned and the score registers the
status as either "inside the thresholds" (normal) or "outside the thresholds" (requires action).
When one of the vitals measured or entered is outside of the thresholds, an action is
recommended.
How does SPS work in Guardian Early Warning Scoring? SPS results in a color-coded circle
displayed next to the measured or entered values. The circle is white for the normal range and red
for outside of the thresholds. As soon as one of the values crosses a threshold, a corresponding
action will be recommended in the action list in the lower part of the screen. If several vitals have
values outside of the thresholds, this will result in a list of actions.
• Modified Early Warning Scoring (MEWS) - A subscore is given for each of the vitals based on
the measured or entered value. When all the required vital signs have been entered or measured,
the subscores are added together to give the MEWS score. Each subscore has a color coding, to
indicate the level of risk associated with it, for example:
Normal White Subscore 0
Observe - at risk Yellow Subscore 1
Warning Orange Subscore 2
Urgent Red Subscore 3
