The therm colorimetry may be used to describe the study of how people perceive color and distinguish between colors. Colorimetry can be used to help people with colorblindness.
Pulse oximetry is a non-invasive method for monitoring a person's O 2 saturation. In its most common (transmissive) application mode, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot.ince pulse oximetry only measures the percentage of bound hemoglobin, a falsely high or falsely low reading will occur when hemoglobin binds to something other than oxygen: 1  Hemoglobin has a higher affinity to carbon monoxide than oxygen, and a high reading may occur despite the patient actually being hypoxemic.
