In this case, the measurement will be more sensitive to interference.

green or methylene blue), skin pigmentation.
C. The measured value may be normal seemingly for the tester who has anemia or dysfunctional
hemoglobin(such
as
carboxyhaemoglobin
(COHb),
methaemoglobin
(MetHb)
and
sulfhaemoglobin (SuHb)), but the tester may appear hypoxia, it is recommended to perform
further assessment according the clinical situations and symptoms.
D. Pulse oxygen only has a reference meaning for anemia and toxic hypoxia, as some severe
anemia patients still show better pulse oxygen measured valued.
E. Contraindication: no
