Clinical Assistive Applications (CAA)
The Clinical Assistive Applications (CAA) function integrates some commonly used
clinical guidelines and tools into the monitor. It puts the currently monitoring parameter
measurements together and provides comprehensive analysis results.
CAA is not intended to replace the competent judgment of a clinician. It must be used in
conjunction with observation of clinical signs and symptoms.
15.1 Early Warning Score (EWS)
The Early Warning Scores (EWS) can help you recognize the early sign of deterioration in
patients based on vital signs and clinical observations. Depending on the score
calculated, appropriate recommendations are displayed.
The monitor supports the following scores:
■ MEWS (Modified Early Warning Score)
■
NEWS (National Early Warning Score)
■ NEWS2 (National Early Warning Score 2)
■
Custom Score
There are two types of scoring tools:
■ Total score: A subscore is given for each parameter based on the measured or
entered value. When all the required parameters are entered or measured, the
subscores are added together to calculate the total early warning score. Each
subscore has a color coding to indicate associated level of risk, When the total
score is outside of the thresholds, actions are recommended. MEWS, NEWS and
NEWS2 can give total scores.
■
IPS (individual parameter score): A color-coded score is given for each parameter
based on the measured or entered value. Each parameter has upper and lower
thresholds. When an individual parameter measured or entered is outside of the
thresholds, actions are recommended.
Custom Score is based on user-defined parameters. It can be a total score or an IPS,
depending on the configuation.
MEWS, NEWS and NEWS2 are intended for adult patients only. The patient category
applied to the Custom Score is defined by Mindray Clinical Score Configuration Tool. For
