Compliance Consultants has worked on concept plans and claims
Compliance Consultants has submitted 510(k) applications for pulse
oximeter (oxymeter). These small devices have created an entire
diagnostic facility to patients that were once available only in labs.
They measure and display the oxygen saturation in the blood. These
devices typically use a complex, proprietary red and infrared energy
(660 nm and 880 nm) energy (plethysmograms) beamed onto the
finger. A sensor assembly measures a complex array of reflected red
and infrared energy. Blood reflections are calibrated to yield the
absorption of oxygen. The calibration is computed by a
computerized, sophisticated algorithm. The law of Lambert Beer is
most common foundation for this algorithm. The results are
displayed as oxygen saturation.
