Notes
(1)
Unobstructed
path
between
the pulse
oximeter
(Oxxiom) and
the iOS (host) device.
Physical obstacles and indoor room geometry may
drastically reduce the effective wireless range.
(2)
Maximum value. Changes in the measurement site
optical properties, environmental conditions, and
device stand-by operation time affect battery life.
Tests conducted in laboratory conditions have
shown that the battery life may be significantly
shortened depending on the aforementioned
changes.
(3)
± 3.5% is the root-mean-square accuracy and
represents approximately 68% of measurements.
Accuracy evaluated during induced hypoxia studies
with human subjects. The studies followed the
pulse oximetry guidelines of ISO 80601-2-61:2011
applicable sections. Please refer to DEVICE
PERFORMANCE section in this guide for a
detailed description regarding Oxxiom’s SpO2
accuracy evaluation.
