Operation
Introduction
To operate the Radical-7R 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, Dual Rainbow Cable or a direct cable sensor to the Patient
Cable Connector of the Radical-7R 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. If utilizing a patient cable or Dual Rainbow Cable, 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. If using an Acoustic Respiration sensor, ensure that the patient's neck
area is clean and dry.
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

, RRa, SpMet, SpCO, SpHb, PI, PVI, and pulse rate.
The readings for SpO

, RRa, SpMet, SpCO, SpHb, SpOC, SpHct, PI, PVI, and pulse rate.
NOTE: “- - -” initially shows in the numeric display fields for all the parameters/measurements
when the Radical-7R 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. In the case of SpHb and PVI, the
numeric value will be displayed upon initial stabilization of the number, and the parameter label
will continue to flash for an additional processing period to reach optimal confidence.
