  • Page 87: Principles Of Operation

    P r i n c i p l e s o f O p e r a t i o n Oximetry Overview The N-550 uses pulse oximetry to measure functional oxygen saturation in the blood. Pulse oximetry works by applying a sensor to a pulsating arteriolar vascular bed, such as a finger or toe.

  • Page 88: Automatic Calibration

    Principles of Operation difference between maximum and minimum absorption (measurements at systole and diastole). By doing so, it focuses on light absorption by pulsatile arterial blood, eliminating the effects of nonpulsatile absorbers such as tissue, bone, and venous blood. There are various matrixes within the OxiSmart XL algorithm. Some are used to assess the severity of conditions presented to the N-550 in measuring SpO and pulse rate.

  • Page 89: Functional Versus Fractional Saturation

    Principles of Operation Functional versus Fractional Saturation This monitor 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.
