Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual 4-1

Operation

Introduction

To operate the Radical-7 Pulse CO-Oximeter effectively, the instrument must be set up

properly and the operator must:

 Know how the Pulse CO-Oximeter derives its readings (see Section 1, Pulse

CO-Oximetry).

 Be familiar with its controls, components and operation.

 Understand its status and alarm messages (see Section 5, Alarm Identification, System

Messages and Section 6, Troubleshooting).

Basic Operation

GENERAL SETUP AND USE

1. Inspect the Pulse CO-Oximeter case for damage.

2. Connect a patient cable or a direct cable sensor to the Patient Cable Connector of the

Radical-7 Pulse CO-Oximeter. Make sure it is a firm connection and the cable is not

twisted, sliced or frayed.

3. If utilizing the Standalone setup, ensure that the power cord is plugged into the Power

Cable Connector of the Docking Station and into the AC power.

4. Select a sensor that is compatible with the Pulse CO-Oximeter before connecting it to the

patient cable or instrument. See section 8, Sensors and Patient Cables. If using a single

patient adhesive or disposable sensor, check that the emitter (red light) and the detector

are properly aligned. Remove any substances that may interfere with the transmission of

light between the sensor’s light source and detector.

5. Attach the sensor to the patient. Refer to the Directions for Use of the sensor.

6. Connect the sensor to the instrument (or patient cable) with the logos lining up; make sure

it is a firm connection.

7. Press the Power/Standby button to turn the Pulse CO-Oximeter on.

8. Make sure the display window is free of alarm and system failure messages (see Section

5, Alarms and Messages).

9. On the display, verify:

 The high and low alarm limits for SpO

, SpMet, SpCO, SpHb, PI, PVI, and pulse rate.

 The readings for SpO

, SpMet, SpCO, SpHb, SpOC, PI, PVI, and pulse rate.

 The remaining duration for the sensor, if applicable.

NOTE: “- - -” initially shows in the numeric display fields for all the parameters/measurements

when the Radical-7 is turned on. As the system starts monitoring, the numeric display fields

update (refresh). The numeric display fields for the parameters/measurements begin to show

numbers during the refresh cycles even though the numbers have not stabilized; during this

period, the measurement label will flash to indicate that the measurement value is being

processed. When the flashing stops, the number has stabilized (less than 15 seconds for SpO

PI and pulse rate; up to 25 seconds for SpCO and SpMet. In the case of SpHb, the numeric value

will be displayed upon initial stabilization of the number (up to 90 seconds), and the parameter

label will continue to flash for an additional processing period to reach optimal confidence (60

seconds).

In the case of PVI, the numeric value will be displayed upon initial stabilization of the

number (up to 120 seconds), and the parameter label will continue to flash for an additional processing

period to reach optimal confidence (60 seconds).
