The OXY100E measures beat-by-beat, blood oxygen saturation (SpO2) level in a noninvasive fashion. The OXY100E outputs four signals simultaneously:
A: SpO2 value (Ch 1, 2, 3, or 4)
B: Pulse Plethysmogram (Ch 5, 6, 7, or 8)
C: Heart pulse rate (Ch 9, 10, 11, or 12)
D: Module Status ( Ch 13, 14, 15, or 16)
These signals are directed to switchable blocks of different MP input channels. Up to four OXY100E modules can be used with a single MP System. The OXY100E has built-in calibration for a simplified setup procedure. Each OXY100E module requires one of the TSD124 series SpO2 transducers.
The OXY100E operates in accordance to the principles outlined by the Lambert-Beer law; this an empirical relationship that relates the absorption of light to the properties of the material through which the light is traveling.
The OXY100E is a noninvasive instrument which measures blood-oxygen percentage levels. The OXY100E probe incorporates light-emitting diodes (LEDs) which face photodiodes through a translucent part of the subject's body, usually a fingertip or an earlobe. One LED is red, with wavelength of 660 nm, and the other is infrared (approximately 910 nm). Light absorption at these wavelengths is different between oxyhemoglobin and its deoxygenated form. The oxyhemoglobin/deoxyhemoglobin ratio can be calculated via the ratio of the absorption of the red and infrared light. In particular, the OXY100E outputs (as a proportional voltage) the percentage of arterial hemoglobin in the oxyhemoglobin state.
