A vascular,pulsatile area (e.g.,fingertip or earlobe)is needed to detect the degree of change in the transmitted light.Factors that affect light transmission (e.g.,sensor movement,fingernail polish)or peripheral arterial pulsations (e.g.,hypotension,anemia)also affect the measurement of SpO?.An awareness of these factors allows for accurate interpretation of abnormal SpO? measurements.Measuring SpO? can be conducted intermittently or continuously to assess ongoing therapies.
