* Oxygen measurements are automatically compensated for changes in barometric pressure.
** An RMS accuracy is a statistical calculation of the difference between device measurements and reference measurements.
Approximately two-thirds of the device measurements fell within +/- ARMS of the reference measurements in a controlled study.
