* Sensitivity is a setting that enables a clinician to tailor the response of the Masimo pulse oximeter to the needs of the particular patient situation. The Max sensitivity mode interprets data even when the signal may be weak, such as during very low perfusion.
† Averaging time is the length of time over which the average of all data points is calculated. Longer averaging times include more historical data, whereas shorter averaging times prioritize newer data.
‡ ARMS 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.
