* ARMS accuracy is a statistical calculation of the difference between device measurements
and reference measurements. Approximately two-thirds of the device measurements fell
b/- ARMS of the reference measurements in a controlled study.
Note:
ARMS is indicative of use with the large adhesive O3
®
Sensor >40kg only for adults and
the pediatric O3
®
Sensor ≥5 kg to <40 kg only for pediatric patients.
[1] Absolute and trending rSO

(ARMS) accuracy were determined by testing on healthy adult
volunteers with light to dark pigmentation in the range of 45% to 85% SavO
2
against 30%
arterial and 70% jugular venous blood oxygen saturations, measured with a laboratory
CO-Oximeter.
[2] Absolute rSO
2
accuracy (ARMS) was determined by testing on pediatric patients ≥5 kg, <40
kg with varying skin pigmentation in the range of 45% to 85% SavO

against 30% arterial and
70% jugular venous blood oxygen saturations, measured with a laboratory CO-Oximeter.
