Normal Patient Monitoring
During normal operation, the Rad-57 Display shows oxygen saturation (as % SpO
2
) on the
upper number and Pulse Rate (in beats per minute) on the lower number.
On each model, a 10-LED bar displays the following parameters:
■ Carboxyhemoglobin saturation (%SpCO) and Perfusion Index (PI) on the Rad-57c.
■ Methemoglobin saturation (%SpMet) and Perfusion Index (PI) on the Rad-57m.
■ Carboxyhemoglobin saturation (%SpCO) and Methemoglobin saturation (%SpMet)
on the Rad-57cm. Low Perfusion Index (PI) is displayed with a single LED on this
model or the numeric value may be viewed by pressing the Display button.
The following sections describe the function of the Rad-57 front panel controls during
normal patient monitoring.

Pressing this button will display the numeric SpCO/SpMet value in place of
the SpO
2
/pulse rate numeric value. Pressing this button again will return to
the SpO
2
/pulse rate numeric value.
NOTE: If any parameter breaches its pre-set alarm limit, the Rad-57 will
automatically display the alarming parameter. Pressing Display during an
alarm condition will enable the display of other parameters for 10 seconds. In
the event of a multi-parameter alarm condition, the SpO
2
/ Pulse Rate display
will take priority.
