compact, and lightweight monitor that noninvasively and
continuously monitors arterial blood oxygen saturation
(Sa02) and pulse rate.
8802 and pulse rate information is conveyed both visually
and audibly. A custom high contrast Liquid Crystal Display
(LCD) with Electroluminescent (EL) backlighting indicates
the Sa02, pulse rate, pulse signal strength, and system
messages. The monitor’s tone generator “beeps” with each
pulse beat. The pulse "beep" momentarily changes to a
lower-tone double “beep” when there is a decrease in Sa02.
The 3040G Oximeter has a flexible alarm system with audible
and visual indicators. The high and low alarm limits for
Sa02 and pulse rate are user adjustable. The audible alarm
and pulse "beep" volume can be adjusted or inhibited by the
user.
The 3040G Oximeter operates on power from the AC line or its
internal battery.
Theory of Operation
The 3040G Oximeter determines
two wavelengths of light, one red and one infrared, through
body tissue to a photodetector. Pulse identification is
accomplished by using plethysmographic techniques, and
oxygen saturation measurements are determined using
spectrophotometric oximetry principles. During measurement,
the signal strength resulting from each light source depends
on the color and thickness of the body tissue, the sensor
placement, the intensity of the light sources, and the
absorption of the arterial and venous blood (including the
time varying effects of the pulse) in the body tissues.
The
3040G
Oximeter
processes
these
signals,
separating
the
time
invariant
parameters
(tissue
thickness,
skin
color,
light
intensity,
and
venous
blood)
from
the
time
variant
parameters
(arterial
volume
and
Sa02)
to
identify
the
pulse
and
calculate
oxygen
saturation.
Oxygen
saturation
calculations
can
be
performed
because
blood
saturated
with
oxygen
predictably
absorbs
less
red
light
than
oxygen
depleted
blood.
Since
measurement
of
Sa02
depends
on
a
pulsating
vascular
bed,
any
condition
which
restricts
blood
flow,
such
as
use
of
a
blood
pressure
cuff
or
extremes
in
systemic
vascular
resistance,
may
cause
an
inability
to
determine
accurate
pulse
and
Sa02
readings.

to the AC LINE connector on the 3040G Oximeter and then to a
hospital grade outlet.
Connect the patient cable to the PATIENT CABLE/PROBE
connector on the rear of the 3040G Oximeter.
Refer to Figures 4-9 and choose either the Finger Probe or
the Universal "Y" Probe for use based on application
requirements.
Connect the probe to the Patient Cable.
Caution: Use only Biochem Finger Probe, Catalog No. 3044 or
Universal "Y" Probe, Catalog No. 3043, with the microSpan
3040G Oximeter.
Starting
Press the front panel On/Off key. The 3040G Oximeter
performs a self-test, lights all display legends, and
displays the software revision. The 3040G Oximeter then
enters the monitoring mode.
The 3040G Oximeter defaults to an eight (8) pulse averaging
mode for Sa02 measurement, but four (4) or sixteen (16)
pulse averaging is available. To put the monitor in the 4
pulse averaging mode, press and hold the DOWN arrow key
while turning the monitor on. The number 4 appears for a
moment in the Sa02 portion of the LCD display. To put the
monitor in the 16 pulse averaging mode, press and hold the
UP arrow key while turning the monitor on. The number 16
appears for a moment in the Sa02 portion of the LCD display.
To return the monitor to the 8 pulse averaging mode, turn
the monitor off and on.
The 3040G Oximeter uses an 8 second pulse rate
average in the 4 or 8 pulse Sa02 averaging mode and a
16 second pulse rate average in the 16 pulse Sa02
averaging mode.
Attaching the Sensor
Both the Finger Probe and the Universal "Y" Probes are
reuseable. See the "User's Maintenance" section on page 17
for probe cleaning instructions.
13

Finger Probe Attach the probe to the finger as shown in
Figure 4 so the cable protrudes along the palm of the hand.
Very long finger nails may make positioning of the probe
difficult, resulting in a poor pulse signal. Use the
Universal "Y" Probe, as shown in Figure 6, for patients with
very long finger nails.
Universal "Y" Probe: Attach the probe to the patient as
shown in Figures 5, 6, 8, or 9, using adhesive strips as
necessary. When using the Universal “Y" Probe on the
finger, attach the LED (light source) portion of the sensor
to the finger nail side of the finger.
Ear Probe Attachment: The Universal "Y“ Probe can be
adapted for use as an ear probe with the Ear Clip. The
Universal "Y" Probe is attached to the Ear Clip as shown in
Figure 7. The Ear Clip is then attached to the patient's
ear lobe as shown in Figure 5.
Verifying the Sensor Placement
Once the probe is attached to the patient, allow several
pulse beats for the monitor to stabilize. Observe the pulse
bar graph located on the LCD Display. If the pulse signal
strength is low, the probe position may need adjustment.
Measuring the Pulse Rate and Sa02
After approximately four or five pulse beats, the Pulse Rate
and Sa02 values are displayed.
The pulse “beep” sounds with each pulse beat when the pulse
tone is enabled.
A lower-tone double "beep" sounds when a drop in Sa02 is
detected.

Interpreting the Patient Alarms
When an alarm limit is violated, a two-tone alarm sounds
(when the alarm is not silenced), the red "ALARM" LED
flashes, and the triangular indicator for the violated alarm
limit flashes. The alarms stop when the alarm limit is no
longer violated.
Press the ALARM SILENCE key to silence the alarm for two (2)
minutes. ALARM SILENCED flashes on the display. Press the
ALARM SILENCE key again to end the two minute alarm silence.
Press and hold the ALARM SILENCE key for three (3) seconds
to silence the alarm indefinitely. ALARM SILENCED is
displayed continuously. Press the ALARM SILENCE key again
to end the indefinite alarm silence mode.
LOW PULSE is displayed when the pulse amplitude is low.
A lower-tone double "beep" sounds when a drop in 9802 is
detected.
Adjusting the Audio Volume
Alarms: Use the Up/Down arrow keys to adjust the audio
alarm volume (when not setting the alarm limits and the
alarm is not silenced).
Pulse "Beep": Silence the audio alarms by pressing the
ALARM SILENCE key (be sure ALARM SILENCED is displayed).
Now use the Up/Down arrow keys to set the pulse "beep"
volume (when not setting the alarm limits). BEEP SILENCED
is momentarily displayed when the pulse "beep" volume
reaches off.
