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

(PLETH) will decrease. In this case, the measurement

2.  For those with a substantial amount of staining dilu-

tion drug (such as methylene blue, indigo green and 

acid indigo blue), or carbon monoxide hemoglobin 

(COHb), or methionine (Me+Hb) or thiosalicylic he-

moglobin, and some with icterus problem, the SpO

determination by this monitor may be inaccurate.

3. The drugs like dopamine, procaine, prilocaine, li-

docaine and butacaine may also be a major factor 

blamed for serious error of SpO

 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
