ANALOG OUTPUT

The Radical-7 Pulse CO-Oximeter can interface with various analog recording instruments

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

■ 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.

CALIBRATION

For measurement instrument calibration purposes, the analog output signals can be set to

either 0 Volts or 1 Volt in the menu system under Output/Analog Output Mode. Calibrate your

analog recording system to those levels before use.

NURSE CALL

The nurse call feature is available when Radical-7 Pulse CO-Oximeter is operating in its

standalone configuration. The nurse call feature on the Radical-7 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.
