    Technical Discussion T e c h n i c a l D i s c u s s i o n Oximetry Overview The N-600x uses pulse oximetry to measure functional oxygen saturation in the blood. Pulse oximetry works by applying an O sensor to a pulsating arteriolar vascular bed, such as a finger or toe.

  • Page 154: Functional Versus Fractional Saturation

    Technical Discussion Functional versus Fractional Saturation The pulse oximeter measures functional saturation -- oxygenated hemoglobin expressed as a percentage of the hemoglobin that can transport oxygen. It does not detect significant amounts of dysfunctional hemoglobin, such as carboxyhemoglobin or methemoglobin. In contrast, hemoximeters such as the IL482 report fractional saturation -- oxygenated hemoglobin expressed as a percentage of all measured hemoglobin, including measured dysfunctional hemoglobins.

  • Page 156: Block Diagram Theory

    Technical Discussion The N-600x uses the information in the O sensor to tailor troubleshooting messages for the clinician. The O sensor contains coding telling the pulse oximeter the type of O sensor being used. When deciding which messages to display, the pulse oximeter determines the O sensor type and recommended patient site for each model.
  • Page 157 Technical Discussion The N-600x contains the Motorola MPC823e PowerPC (823e) microprocessor. As shown in the block diagram above, the 823e provides the bulk of the functionality in the instrument, acting as the “master” controller, while NELL-1A Oximetry Module handles the pulse oximetry functions and the Linear Power Supply (LPS) board microcontroller handles the AC/Battery power management tasks, Communications between the N-600x board and the Nell-1A module takes place over an asynchronous isolated bidirectional serial link.

The Patient Isolated power supply for the N-600x is an isolated switcher which generates +3.3, +5, and +12 volts. The patient is connected to the N-600x via an O sensor and pulse oximetry cable.
