Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual 2-5

System Description

HANDHELD FRONT PANEL (CONTINUED)

SpOC*

MEASUREMENT

DISPLAY

The measurement of total oxygen content is displayed in units of

milliliter per deciliter.

SENSOR 4 Hrs

SENSOR TIME

Sensor Time displays the amount of time remaining (for SpHb

Rainbow Reusable sensors) in the lower, right-hand corner of the

screen. The Sensor Time is displayed in “X” Hrs” or “XX Min.” As the

sensor monitors the patient, the amount of time decreases to “0”.

Once the sensor time shows ”0”, the sensor must be replaced.

The Sensor Time and the Time and Date Indicator show in the

same location when the Time and Date Indicator is set to show on

the screen. Subsequently, the Sensor Time replaces the Time and

Date Indicator for 2 minutes at the following Sensor Times: 4 hours,

2 hours, 1 hour and 0 minutes. Refer to Section 4, Sensor Time

Remaining for additional information. Once the Sensor Time reads 2

minutes, the Sensor Time will continue showing as it decreases to “0”.

TIME AND DATE

INDICATOR

The Time and Date Indicator displays the current time and date. The

time is displayed in 12 or 24 hour format. The date is displayed in dd/

mm/yy or mm/dd/yy format. Select the date and time display formats

in the Clock menu.

PLETH

VARIABILITY

INDEX

PVI is displayed as a percentage. The lower the number, the less vari-

ability there is in the PI over a respiratory cycle.

SIGNAL IQ

The Signal IQ shows the acquired signal quality and the timing of

the pulse. A tall vertical line indicates a high quality signal, while a

short vertical line indicates a low quality signal. The Signal IQ will

be displayed as a single, pulsating bar in the Numbers mode.

PULSE WAVEFORM

DISPLAY

The Pulse Waveform Display shows the acquired plethysmographic

waveform. The plethysmographic waveform is scaled with signal

strength. Signal strength is defined as the relation of arterial pulsatile

signal to the non-pulsatile signal component.

BRIGHTNESS

LEVEL

The Brightness level icon displays when utilizing the Backlight/

Contrast button.

3.00

PERFUSION INDEX

The Perfusion Index indicates numerically the percentage of

pulsatile signal to non-pulsatile signal (pulse strength).

APOD

SENSITIVITY

The sensitivity icon is shown on the Radical-7 display to indicate

if the Radical-7 is set to operate in Normal, Maximum (MAX) or

Adaptive Probe Off Detection (APOD) mode. When in Normal mode,

this area will appear blank.

140

PULSE RATE

ALARM LIMITS

DISPLAY

The Pulse Rate Alarm Limits Display shows the upper and lower

pulse rate alarm limits. When an alarm limit is exceeded, the pulse

rate value and the violated limit flashes.

FastSat

FASTSAT

The FastSat

label is shown on the Radical-7 display whenever the

Radical-7 is set to operate in the FastSat mode.

PULSE RATE

The Pulse Rate Measurement Display shows the patient’s pulse rate

in beats per minute. The upper and lower pulse rate alarm limits are

also displayed next to the pulse rate measurement. The pulse rate is

calculated and the display is updated at a frequency of once per second.

* For instruments that include SpMet, SpCO and SpHb parameters: the SpMet, SpCO, SpHb and SpOC parameters/

measurements will be dimly lit in the display screen if a patient cable is not attached or a non-Rainbow sensor is being used.

NOTE: The Pulse CO-Oximeter display view will be different without the optional SpCO, SpMet and SpHb

parameters/measurements.
