3.3. Clinical restrictions
A. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow of the
testee is required. For a testee 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.
B. 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.
C. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major
factor blamed for serious error of SpO
2
measure.
D. The SpO
2
value serves only as a reference value for judgement of anemic anoxia and toxic
anoxia, some patients with serious anemia may also report good SpO
2
measurement.
