SpO

monitoring procedure
1. Verify that the SpO
2
sensor cable is connected to the monitor.
2. Attach the SpO
2
finger clip sensor to the end of the patient’s index finger, as shown
below. The sensor can be attached to the patient when the monitor is on or off, and
during an NIBP cycle.
Within a few seconds, the pulse amplitude indicator reflects the rate and strength of
the pulse.
Within less than 20 seconds, the SpO
2
window displays the SpO
2
measurement and
a numeric pulse rate value appears in .
To adjust the volume of the SpO
2
pulse tone, see “Changing the volume of the pulse
tone” on page 26.
Caution Some sensors might not work with some patients. If, after 20 seconds,
a properly functioning sensor fails to discern a pulse, do the following:
1. Adjust or reposition the sensor. If the failure continues:
2. Use a different type of sensor.
WARNING Do not use an SpO
2
finger clip sensor and a blood pressure cuff
simultaneously on the same limb. To do so will result in inaccurate pulse rate and
perfusion readings, and could cause erroneous pulse rate alarms.
Note During an SpO
2
measurement, the displayed pulse rate is derived from the SpO
2
sensor. Otherwise, the pulse rate is derived from NIBP.
Detaching the sensor during an SpO
2
measurement triggers an alarm.
If alarms are set for SpO
2
or pulse rate, a condition of no pulse for between 5 and
10 seconds causes an alarm.
If SpO
2
is being measured continuously on a patient over an extended period,
change the location of the sensor at least every three hours or as indicated by
the directions supplied with the sensor.
