Model 2001 Service Manual Rev. 01
Model 2001 is calibrated to display “functional” saturation. This differs from the “fractional”
saturation value displayed by most co-oximeters.
Functional saturation represents the amount of oxyhemoglobin as a percentage of the
hemoglobin that can be oxygenated. Dysfunctional hemoglobins (COHb and METHb) are not
included in the measurement of functional saturation.
Pulse Rate is calculated by measuring the time interval between the peaks of the infrared light
waveform. The inverse of this measurement is displayed as pulse rate.
Model 2001 must be used in conjunction with SuperBright™ saturation sensors. (An CHECK
SENSOR SITE display message indicates a non-SuperBright™ Sensor may be in use.)
Indications and Usage
The Model 2001 Pulse Oximeter Monitor is intended to be used for monitoring oxygen
saturation and pulse rate in all critical monitoring environments including ventilatory support
and anesthesia. Model 2001 is designed to monitor all patient areas including adult, pediatric
and neonatal.
