ZOLL M Series Defibrillator Rev M - Manual (Page 11)

Pulse Oximetry (SpO
2
)
SpO
2
- 9
When positioned properly, the:
• emitter and the detector are vertically aligned
• digit completely covers detector window
• shiny contacts on the sensor are facing up
6. Lift the clear plastic protective cover from the female
end of the patient cable, then plug the sensor cable’s
male connector all the way into the patient cable
connector (see Figure 5).
7. Lower the clear plastic protective cover over the
connection to secure it (see Figure 6).
8. Connect the SpO
2
patient cable to the SpO
2
connector on the back of the M Series unit as shown
in Step 4 of “SpO2 Setup” on page 6.
Ensuring Accurate SpO

Monitoring
The following general points will aid in ensuring oximetry
monitoring success:
• Choose a site that is well perfused and allows for
proper alignment of the light emitter and detector.
• Select a site that has unrestricted blood flow.
• Do not restrict blood flow when securing a sensor
with tape.
• Do not select a site near potential sources of
electrical interference (electrical cords, for
example).
• Do not use a damaged sensor or one with
exposed electrical circuits.
• Ensure that the sensor site is not subject to
excessive motion. Excessive motion may
adversely affect the performance of the sensor.
• Inspect the SpO
2
sensor site at least once every
two (2) hours to ensure adhesion, skin integrity,
and correct alignment of the light emitter and
detector. Should alterations of skin integrity occur,
remove the sensor and reapply at another
recommended site. Avoid application of the sensor
to edematous or fragile tissue.
• Remove and reposition the sensor every eight (8)
hours and, if indicated by circulatory condition or
skin integrity, reapply to a different monitoring site.
• Do not wrap the adhesive too tightly and do not
use additional tape to secure the sensor, as this
can cause venous pulsations that could potentially
lead to inaccurate saturation measurements.
• If the sensor fails to track the pulse consistently,
the sensors may be incorrectly positioned.
Reposition the sensor or choose a different
monitoring site.
• Ensure that the signal strength bar graph indicates
the presence of a strong signal associated with
each heart beat.
• Avoid placing the SpO
2
sensor on any extremity
with an arterial catheter, blood pressure cuff, or
intravascular line.
Checkout Procedure
1. Connect the sensor to the SpO
2
patient cable and
attach the sensor to test subject (yourself).
2. Connect the SpO
2
patient cable to the SpO
2
connector at the back of the M Series unit.
3. Turn the selector switch to MONITOR mode (ON for
AED units, then select “Manual Mode”).
4. With alarms enabled, verify that the patient alarms
are functional by placing the sensor on your finger
and adjusting the high and low limits until:
• a continuous audio tone sounds
• the alarming parameter's value is highlighted and
the alarm bell flashes on the display
5. Disconnect the ECG cable and verify that your pulse
rate is equal to the rate that appears on the M Series
heart rate display.
6. Verify the sensor alarms are functional by removing
the sensor from the sensor site.
• “CHECK SpO2 SENSOR” appears in the
message area of the graphic display.
• a two-beep audio tone sounds.
7. Unplug the sensor from the M Series unit. Make sure:
• “CHECK SpO2 SENSOR” message appears
• a two-beep audio tone sounds.
8. Verify second waveform display:
• Press the Wave2 softkey
• Verify that the plethysmographic waveform
appears and repeats at test subject's (your own)
pulse rate or disappears if originally present.
Cleaning and Reuse of Sensors
Reusable sensors can be cleaned as follows:
1. Disconnect the sensor from the patient cable.
2. Wipe the entire sensor clean with a 70% isopropyl
alcohol pad.
3. Allow the sensor to air dry before returning it to use.
Cleaning and Reuse of Patient Cables
Patient cables can be cleaned as follows:
1. Disconnect the sensor from the patient cable (if
attached).
2. Disconnect the cable from the rear of the M Series
unit.
3. Wipe the cable clean with a 70% isopropyl alcohol
pad.
4. Allow the cable to dry before returning it to use.
