sat 805 Pulse Oximeter
Safety
13
–
The presence of carboxyl (HbCO)-, methaemoglobin, (Hbmet) or diluted dyes or substances
containing dyes in the blood stream can influence the measurements and can lead incorrectly to
higher values.
–
When using the pulse oximeter near equipment, which emits strong electromagnetic signals, (e.g.
mobile telephones, monitors, etc.) the functionality can be reduced.
–
SpO
2
is empirically calibrated to functional arterial oxygen saturation in healthy adult volunteers with
normal levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb). A pulse oximeter cannot
measure elevated levels of COHb or MetHb. Increases in either COHb or MetHb will affect the
accuracy of the SpO
2
measurement.
–
Elevated levels of Methemoglobin (MetHb) will lead to inaccurate SpO
2
measurements.
When elevated levels of MetHb are suspected, laboratory analysis (co-oximetry) of a blood sample
should be performed.
–
Elevated levels of Carboxyhemoglobin (COHb) will lead to inaccurate SpO
2
-measurements. When
elevated levels of COHb are suspected, laboratory analysis (co-oximetry) of a blood sample should be
performed.
–
Elevated levels of Total Bilirubin may lead to inaccurate SpO
2
measurements.
–
Severe anemia may cause erroneous SpO
2
readings.
