use a disposable adhesive sensor that may tolerate more

motion.

• Replace the sensor.

PROBLEM: The SpO

value or the pulse rate changes

rapidly; the pulse amplitude bar is erratic.

CAUSE:

• Excessive patient motion may be making it impossible

for the SpO

function to find a pulse pattern.

• An electrosurgical unit (ESU) may be interfering with

performance.

SOLUTION:

Check the patient.

• If possible, keep the patient still; check whether the

sensor is applied securely and properly, and replace it if

necessary; move the sensor to a new site; use a sensor

that tolerates more motion.

If an ESU is interfering:

• Move the SpO

cable as far from the ESU as possible.

• Plug the Monitor and the ESU into different AC circuits.

• Move the ESU ground pad as close to the surgical site as

possible.

• The sensor may be damp or may need to be replaced

with a new sensor.

PROBLEM: The oxygen saturation measurement does not

correlate with the value calculated from a blood gas

determination.

CAUSE:

• The SpO2 calculation may not have correctly adjusted

for the effects of pH; temperature; CO2; fetal

hemoglobin; or 2,3-DPG.

• Accuracy can be affected by incorrect sensor application

or use; intravascular dyes; bright light; excessive patient

movement; venous pulsations; electrosurgical

interference; and placement of a sensor on an extremity

that has a blood pressure cuff, arterial catheter, or

intravascular line.
