namePerfusion index Blood Postductal Pulse oximetry
descriptionThe perfusion index measures the strength of the pulse at a sensor site and is the ratio of the pulsatile and nonpulsatile components of the pulse oximetry signal. Postductal measurement indicates that the measurements are taken using a pulse oximetry device placed in an anatomical location whose blood supply originates from the aorta after the junction of the aorta with the ductus arteriorsus (usually either the right or left foot).

propertyRatio
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemBld.postductal
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
