❋1 This device is calibrated to display functional oxygen saturation.
❋2 SpO2 70~100% hypoxia was induced in healthy male and female adult volunteers with light skin and dark
skin. Accuracy was checked in no motion conditions against a laboratory CO-oximeter and an ECG monitor.
Variability distribution at this accuracy was 1SD. 1SD covers 68% of all data.
❋3 SpO2 70~100% hypoxia was induced in healthy male and female adult volunteers with light skin and dark
skin. Accuracy was checked by 1~2cm tapping 2~4 times per second and by 2~3cm irregular tapping 1~5
times per second against a laboratory CO-oximeter and an ECG monitor. Variability distribution at this accu-
racy was 1SD. 1SD covers 68% of all data.
❋4 In a laboratory test, in the range of 70~100% SpO2, accuracy in low perfusion conditions was checked against
the Biotec Index2 Simulator and the Masimo Simulator, both of whose signal strength is 0.02% or more and
permeability 5% or more. Variability distribution at this accuracy was 1SD. 1SD covers 68% of all data.
❋5 The materials accessible to the patient and the user comply with ISO 10993-1.
❋6 All the sensors and patient cables that can be used with this device have been tested and verified by using the
Masimo/MX-1 module pulse oximeter technology.
❋7 Since the measurements taken by the pulse oximetry equipment are statistically distributed, only about two-
thirds of them fall in the accuracy (Arms) range of values obtained with a CO-oximeter.
❋8 Even if the power supply is interrupted due to power failure, disconnection of the power plug, or some other
cause, the preselected settings will be retained in the memory. When the power supply is resumed, the unit
will start operation with the last selected settings.
❋9 The above specifications apply when the sensor and the patient cable specified by Atom are used. For in-
formation on the sensor and the patient cable specified by Atom, contact your local Atom representative.
