Clinical Assistive Applications (only available for the
independent external display)
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 can improve the clinician’s working efficiency. However, it is not directly used for diagnosis and cannot not
replace the clinician’s judgement.

Early Warning Score (EWS)
The Early Warning Score (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
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. Both MEWS, NEWS and NEWS2 can give total scores.
Custom Score is based on user-defined parameters.
MEWS and NEWS and NEWS2 are intended for adult patients only. The patient category of the Custom Score is
defined by the Mindray Clinical Score Configuration Tool. For more information, see
Mindray Clinical Scoring
Config Tool Instruction for Use (P/N: 046-012986-00).
WARNING
•
The EWS scores and recommended actions are for reference only and cannot be directly used for
diagnostic interpretation.
•
EWS cannot be used as an prognosis index. It is not a clinical judgement tool. Clinicians must use
their clinical judgement in conjunction with the EWS tool at all times.
•
MEWS and NEWS are intended for adult patients only. NEWS is not applicable to pregnant woman
and COPD (Chronic Obstructive Pulmonary Disease) patients.
NOTE
•
The EWS scores does not trigger any alarms, and cannot used for continuous monitoring.
