3.3 Clinical Restrictions
1.
As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow of subject is
required. For a subject with weak pulse due to shock, low ambient/body temperature, major
bleeding, or use of vascular contracting drug, the SpO
2
waveform (PLETH) will decrease. In this case,
the measurement will be more sensitive to interference.
2.
For those with a substantial amount of staining dilution drug (such as methylene blue, indigo green
and acid indigo blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or
thiosalicylic hemoglobin, and some with icterus problem, the SpO
2
determination by this monitor
may be inaccurate.
3.
The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor
blamed for serious error of SpO
2
measure.
4.
As the SpO
2
value serves as a reference value for judgement of anemic anoxia and toxic anoxia,
some patients with serious anemia may also report good SpO
2
measurement.
