◆
Below 0.3 indicates low perfusion . When PI is below 0.3, a question mark (?)
is displayed to the right of the SpO
2
value, indicating that the SpO
2
value
may be inaccurate. Reposition the SpO
2
sensor or find a better site. If low
perfusion persists, choose another method to measure oxygen saturation if
possible.
5. Pulse rate (derived from pleth wave): detected pulsations per minute. Obtain PR
through the SpO
2
or NIBP measurement. When simultaneously measuring NIBP
and SpO
2
, the PR source is from SpO
2
.
NOTE
•
If the message "SpO2 Low Perf." or "SpO2 Weak Pulse" displays, check sensor
application, re-apply or remove the sensor if necessary, to obtain a better
signal.
•
A function tester or SpO
2
simulator can be used to verify the sensor
functions.
•
A function tester or SpO
2
simulator can be used to determine the pulse rate
accuracy.
•
A function tester or SpO
2
simulator cannot be used to assess the accuracy of
an SpO
2
module or an SpO
2
sensor.
7.2 Safety
WARNING
•
Only use SpO
2
sensors specified in this manual. Follow the SpO
2
sensor’s
instructions for use and adhere to all warnings and cautions.
•
When a trend toward patient deoxygenation is indicated, blood samples
should be analyzed by a laboratory co-oximeter to completely understand
the patient’s condition.
•
Prolonged monitoring may increase the risk of undesirable changes in skin
characteristics, such as irritation, reddening, blistering or burns. Inspect the
sensor site every two hours and move the sensor if the skin quality changes.
Change the application site every four hours. For neonates, or patients with
poor peripheral blood circulation or sensitive skin, inspect the sensor site
more frequently.
