Safety Information, Warnings, and Cautions
Performance Warnings and Cautions
WARNING: The Early Warning Score (EWS) feature is intended to help clinicians calculate Early Warning Scores based upon established methods.WARNING: The Early Warning Score (EWS) feature is not intended as a definitive clinical assessment of the patient’s condition. The result should be evaluated in conjunction with the patient’s clinical status and confirmed with additional diagnostic tests consistent with each hospital’s policy. Any concern about a patient’s clinical condition should prompt an urgent clinical review, irrespective of EWS.WARNING: Confirm the Early Warning Score (EWS) being used is suitable for the patient type. Certain EWS systems may exclude certain patient types (e.g. Children <16 years, pregnant women) because the physiological response to acute illness can be modified.WARNING: Confirm the Early Warning Score (EWS) being used is suitable for the patient’s condition. Certain EWS systems may be unreliable on patients with certain conditions (e.g. spinal cord injury, tetraplegia, high-level paraplegia) owing to functional disturbances of the autonomic nervous system.Note: The Early Warning Score (EWS) is a static calculation based upon the captured and manually inputted parameter data at the time of the calculation request.
Operation
Early Warning Score (EWS)
The EWS is an optional feature of Rad-97 and must be configured by qualified Masimo personnel only.Rad-97 has the ability to automate Early Warning Score (EWS) calculations based upon published standards such as National Early Warning Score (NEWS)*, Pediatric Early Warning Score (PEWS), or can be customized to match a facility’s protocol.The following information is an example of when Rad-97 is configured with National Early Warning Score (NEWS) calculations.EWS on Rad-97 is aligned with the NEWS system established by the Royal College of Physicians* using seven (7) physiological contributors as the basis of the scoring system.Based on NEWS, each physiological contributor is scored from 0 to 3 according to the mapping from its range to a score (for example, pulse rate from 51 to 90 equates to a 0score). All of the scores are aggregated to provide the NEWS.The EWS feature works by automating established EWS calculations based upon all of the following contributors:
- Oxygen Saturation (SpO2)
- Pulse Rate (PR)
- Respiration Rate (RR)
- Body Temperature (TEMP)
- Systolic Blood Pressure (SYS)
- Level of Consciousness (LOC)
- Supplemental O2 (Sup. O2)
Rad-97 can also be configured** to include the following additional contributors:
- Respiratory Distress (RD)
- Capillary Refill Time (CRT)The EWS calculation can be performed one of two (2) ways:
- EWS Calculation Using Vital Signs Check: When in Vital Signs Check (VSC) Mode, through VSC operation. See EWS Calculation Using Vital Signs Check (VSC) on page 12.
- EWS Calculation Using EMR Push: When connected to Patient SafetyNet and an EMR system, through EMR Push operation. See EWS Calculation Using EMR Push on page 11.For information on how EWS is calculated, see How the EWS is Calculated on page 10.*Royal College of Physicians. National Early Warning Score (NEWS): Standardising the assessment of acute illness severity in the NHS. Report of a working party. London: RCP, 2012.**Configured by authorized personnel only.

How the EWS is CalculatedThe following information is an example of when Rad-97 is configured with National Early Warning Score (NEWS) calculations. Individual EWS contributors are scored in accordance with the guidance provided by NEWS.Note: These scores are a reflection of NEWS standards; they may not be reflective of NEWS if Rad-97 is customized.
| Score/Physiological Parameters | 3* | 2 | 1 | 0 | 1 | 2 | 3* |
| Oxygen Saturation (SEO ) | ≤91 | 92-93 | 94.95≥ | ≥96 | — | — | — |
| Pulse Rate (PR) | ≤40 | — | 41-50 | 51.90 | 91-110 | 111-130 | ≥131 |

* A score of 3 is representative of an extreme variation in a single physiological parameter.
EWS Calculation Using EMR PushEWS Calculation when in Continuous Mode is performed through EMR Push when Rad-97 is connected to Patient SafetyNet and an EMR system and a patient is admitted.For more information about admitting a patient and using EMR push, see Patient Admit/Discharge and EMR Push in the Operator’s Manual, Rad-97™ Pulse CO-Oximeter®.
- To perform an EWS Calculation Using EMR Push, select the EMR Push icon
. - .Manually input any EWS contributors not automatically captured.Note: Automatically captured data cannot be manually adjusted. Manual-entry contributors will be provided with a drop-down or slider to allow data entry.
- Select the Review button. The EWS individual contributor scores (1) and EWS aggregate score (2) are displayed at the top of the EMR Push: Review screen.
- Select the Submit button to send the data to the EMR system. The individual contributor scores and EWS aggregate scores and are sent to the EMR system. Select the Back button to return to the EMR Push screen.
.
EWS Calculation Using Vital Signs Check (VSC)
When Rad-97 is in Vital Signs Check Mode, the EWS Calculation is performed when a Vital Signs Check session is saved or sent. When the Rad-97 is connected to Patient SafetyNet and an EMR system, the VSC session and EWS calculations are sent to the EMR.For more information about Vital Signs Check (VSC) mode and operation, see the Addendum, Rad-97™ Pulse CO-Oximeter® with Vital Signs Check.
- To perform an EWS Calculation, perform a Vital Signs Check. When complete, select the Next button. The EWS individual contributor scores (1) and EWS aggregate score (2) are displayed at the top of the VSC session screen. Scroll to the bottom of the VSC screen and manually input any EWS contributors not automatically captured.Note: Automatically captured data cannot be manually adjusted. Manual-entry contributors will be provided with a drop-down or slider to allow data entry.After selecting dates for additional contributors, they are reflected in the EWS information.
- Select the Save or Send button.• When NOT connected to Patient SafetyNet the Save button is displayed. The individual contributor scores and EWS aggregate score are saved in a session on Rad-97 along with the VSC results. See Sessions in the Addendum, Rad-97™ Pulse CO-Oximeter® with Vital Signs Check.• When connected to Patient SafetyNet the Send button is displayed. The individual contributor scores and EWS aggregate scores are sent to the EMR system along with the VSC results. A session is also saved on Rad-97.
After selecting dates for additional contributors, they are reflected in the EWS information.
EWS Clinical Risk Level Indicators
WARNING: The Early Warning Score (EWS) feature is intended to help clinicians calculate Early Warning Scores based upon established methods.WARNING: The Early Warning Score (EWS) feature is not intended as a definitive assessment of the patient’s condition. The result should be evaluated in conjunction with the patient’s clinical status and confirmed with additional diagnostic tests consistent with each hospital’s policy.Clinical risk levels default to those established by the Royal College of Physicians forNEWS.The aggregate EWS score on Rad-97 provides the following color indicators for different clinical risk levels:
| EWS Score | Clinical Risk | Aggregated Score Color |
| 0 or an aggregate EWS of 1 to 4 | Low | Green |
| Individual parameter score of 3OrAggregate EWS score of 5 to 6 | Medium | Yellow |
| Aggregate EWS of 7 or higher | High | Red |
E IndicatorThe E Indicator appears when a contributor exceeds a user-defined threshold. Thresholds are customized using the Masimo Instrument Configuration Tool (MICT) by authorized personnel. When the contributor threshold is exceeded, the overall EWS score is replaced with an “E” in a red box (see screenshot below). Each contributor can be configured to have an E Indicator.
