SpO2 -- Using the Pulse Oximeter
The primary use of the device is as a ventilator -- the pulse oximeter operates
only
when the
device is providing ventilation.
The following conditions can affect the pulse oximeter reading:
•
The sensor is too tight.
•
There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp,
or sunlight.
•
A blood pressure cuff is inflated on the same extremity as the one with a SpO2 sensor
attached.
•
The patient has hypotension, severe vascoconstriction, severe anemia, or hypothermia.
•
There is an arterial occlusion proximal to the sensor.
•
The patient is in cardiac arrest or is in shock.
The SpO
2
display is active only when the pulse oximeter is connected. The pulse oximeter is in
standby (and displays
stby
in the parameter window) when
•
No SpO
2
sensor is connected
•
The sensor is off the patient during start up
•
You place the pulse oximeter in standby
Note:
You can place the pulse oximeter in standby only when the probe is disconnected from
the patient. A valid signal automatically brings the pulse oximeter out of standby.
