monitoring is indicated for use when it is beneficial to assess a patient’s
oxygen saturation level.

ence of certain circumstances, such as hemoglobin saturated with compounds
other than oxygen, (such as carbon monoxide), hypothermia, hypovolemia,
patient movement, nail polish and excessive ambient light.
