The following factors can lead to inaccurancy
- continuous motion of the limb
- Abnormal hemoglobin e.g. Fetal hemoglobin, Carboxyhemolgobin, Methemoglobin
- Intravascular contrast or dye
- Poor circulation, e.g. hypovolemic shock, peripheral shutdown, peripheral vascular disease, Raynaud's phenomenon
