Artifactual pulse oximetry signals during nonrhythmic motion(i.e., gross arm motion; top panel) and during Parkinsonian tremor (lowerpanel). Solid line denotes Masimo signal extraction technology(SET), aimedat minimizing spurious pulse oximetry readingsdue to motion artifact; dashed line denotes conventional pulse oximetry.Spurious changes in SpO2 were less with MasimoSET than with conventional pulse oximetry.
