NOTE
• Each sensor requires site-specific application procedures. The quality of the patient’s
pulse oximetry measurements and pulse signals may be adversely affected by certain
environmental factors, by oximetry sensor application errors, and by patient conditions.
Any of these factors can interfere with the ability to detect and display measurements
and may result in a loss-of-pulse condition. If the SpO
2
measurement is questionable,
confirm the patient’s vital signs by alternate means and then check the pulse oximeter
for proper operation.
• Patients with anemia and/or significant concentrations of dysfunctional hemoglobins
(such as carboxyhemoglobin, methemoglobin, and sulphemoglobin) may appear to have
normal saturation values while actually being hypoxic. Further assessment, using
means other than pulse oximetry, is recommended for such patients.
• Poor SpO
2
signal detection is indicated by a low PI (perfusion Index) value, and various
SpO
2
messages.
6.2.3.2. Setup Checklist
• Only one oPOD with pulse oximetry sensor is used
• Correct SpO
2
sensor attachment is selected for each patient size
• The sensor is completely dry after cleaning
• Sensor is positioned correctly to the patient
• SpO
2
parameter is selected
• SpO
2
is selected to be displayed through the Monitor Setup patient parameters menu
6.2.3.3. Testing SpO2 Alarm Functionality
• Place the SpO2 sensor with attachment on a finger and wait for the measurement value
to appear in the SpO2 vital sign display box.
• Remove finger from sensor
• Verify:
1. SpO2 Probe Off or Searching message appears in the alerts message area
2. SpO2 waveform flat lines
3. Alarm tone sounds
This completes the test of the alarm system
6.2.4. Changing SpO
2
settings
6.2.4.1. Sweep Rate
The screen sweep rate setting determines the speed at with the SpO
2
waveform traces moves
across the display. You can change the waveform sweep rate between 25 mm/s and 50 mm/s
by selecting the appropriate setting under the SpO
2
menu.
To adjust the sweep rate follow these steps:
1. Touch the SpO
2
vital sign box
2. Touch “Sweep Rate”
3. Select “25 mm/s” or “50 mm/s”
4. Touch Back button to close the menu
