Note 1: The claims of SpO
ments taken over the full range. By artificial inducing, get the stable oxygen level to
the range of 70 % to 100 % SpO
ary standard pulse oximeter equipment and the tested equipment at the same time,
to form paired data, which are used for the accuracy analysis.
There are 12 healthy volunteers (male: 6. female: 6; age: 18~50; skin color: black: 2,
light: 8, white: 2) data in the clinical report.
Note 2: Because pulse oximeter equipment measurements are statistically distrib-
uted, only about two-thirds of pulse oximeter equipment measurements can be
expected to fall within ±Arms of the value measured by a CO-OXIMETER.
Note 3: Patient simulator has been used to verify the pulse rate accuracy, it is stated
as the root-mean-square difference between the PR measurement value and the
value set by simulator.
Note 4: Percentage modulation of infrared signal as the indication of pulsating sig-
nal strength, patient simulator has been used to verify its accuracy under conditions
of low perfusion. SpO2 and PR values are different due to low signal conditions,
