D. Do not fix the SpO
inaccurate measure of the SpO
E. Excessive ambient light may affect the measuring result. This includes fluorescent lamps, dual
ruby lights, infrared heaters, direct sunlight etc.
F. Strenuous action of the patient or extreme electrosurgical interference may also affect accuracy.
G. Patient cannot use nail enamel or other makeup.
H. Please clean and disinfect the device after operating it according to the User Manual (7.1).

6.3. Clinical Restrictions

A. As the measurement is taken on the basis of arteriole pulse, substantial pulsating blood flow of
the subject is required. For a subject with weak pulse due to shock, low ambient/body
temperature, major bleeding, or use of vascular contracting drugs, the SpO
will decrease. In this case, the measurement will be more sensitive to interference.
B. For those with a substantial amount of staining dilution drugs (such as methylene blue, indigo
green and acid indigo blue), carboxyhemoglobin (COHb), methionine (Me+Hb) or thiosalicylic
hemoglobin, and some with an icterus problem, the SpO
inaccurate.
C. Drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor
blamed for serious errors of SpO
D. As the SpO value serves as a reference value for judgment of anemic anoxia and toxic anoxia,
2
some patients with serious anemia may also report good SpO
