ANALOG OUTPUT
The Radical-7R Pulse CO-Oximeter can interface with various analog recording devices
and/or strip chart recorders through its Analog Output connector located on the back of
the Docking Station. Depending on the configuration of the Output menu, the following
parameters are output continuously on the Analog 1 and Analog 2 channels:
■
SpO
2
■
Pulse
rate
■
Plethysmographic
waveform
■
Signal IQ
The output signals vary from approximately 0 to 1 volt in a linear fashion.
NOTE:
The actual Analog 1 and Analog 2 output voltage that are generated may not
exactly range between 0.0V to 1.0V. A variance of ± 40 mV is acceptable.
NURSE CALL
The nurse call feature is available when Radical-7R Pulse CO-Oximeter is operating in its
standalone configuration. The nurse call feature on the Radical-7R Pulse CO-Oximeter is
based on the relay closing or opening depending on alarm, Low Signal IQ events or both.
For maximum flexibility, either normally open (pin 6) or normally closed (pin 7) signals are
available. Only qualified personnel should connect one of these two signals and common (pin
12) to a hospital’s nurse call system. During an alarm condition, or a Low Signal IQ event,
depending on the configuration of the output menu, the normally open pin will be connected
to the common pin and the normally closed will be disconnected. In addition, the nurse call
polarity can be inverted to accommodate various nurse call station requirements.
The nurse call relays have the following electrical specifications per switch:
PARAMETER
SPECIFICATION
MAX VOLTAGE
100VDC or AC peak
MAX CURRENT

WARNING:
THE NURSE CALL FEATURE IS DISABLED WHEN THE AUDIBLE
ALARMS ARE SILENCED WHILE THE NURSE CALL SETTING IN THE
OUTPUT MENU IS SET TO “ALARMS”.
