System Description
HANDHELD FRONT PANEL (CONTINUED)
22
SIGNAL IQ
The Signal IQ shows the acquired signal quality and the timing of the
pulse.
23
8
PERFUSION
INDEX
The Perfusion Index indicates numerically the percentage of
pulsatile signal to non-pulsatile signal (pulse strength).
24
APOD
SENSITIVITY
The sensitivity icon is shown on the Radical-7R display to indicate
if the Radical 7R is set to operate in Normal, Maximum (MAX) or
Adapative Probe Off Detection (APOD) mode. When in normal mode,
this area will appear blank.

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.
26
70
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.

SIQa
MEASUREMENT
DISPLAY
The SIQa Measurement Display shows the confidence level of the
Acoustic Respiration measurement signal quality as a percentage
between 1 and 100.

RESPIRATION
RATE ALARM
LIMITS DISPLAY
The Respiration Rate (RRa) Alarm Limits Display shows the
upper and lower respiration rate alarm limits. When an alarm
limit is exceeded, the respiration rate value and the violated
limit flashes.

RESPIRATION
RATE
MEASUREMENT
DISPLAY
The Respiration Rate Measurement Dsiplay shows the patient's
respiration rate in breaths per minute (bpm). The upper and
lower alarm limits are also displayed next to the respiration rate
measurement.
30
41
SpHct
MEASUREMENT
DISPLAY
The measurement of hematocrit is displayed in units of percentage
SpHct .
31
SIQa
ACOUSTIC (SIQa)
INDICATOR
SIQa displays the confidence level of the measured signal. The
SIQa value ranges from 0-100% with each bar representing 10%.
The bars are colored green unless the SIQa value is in the range 0
> = 10%, in which case the signal bar shall be colored RED.
32
RI
RESPIRATION
INDICATOR
The Respiration Indicator (RI) displays the sound level of the measured
signal. A 10 segment bar graph represents the acoustic signal at the
respiration sensor. RI values range from
0 to 1.
0 - no green bars lit
0 - 0.20 - middle 2 bars lit.
0.20 - 0.40 - middle 4 bars lit
0.40 - 0.60 - middle 6 bars lit
0.60 - 0.80 - middle 8 bars lit
0.80 - 1.00 - all bars lit
