1) Accuracy specifications are based on controlled hypoxia studies with healthy, non-smoking adult volunteers over the specified saturation SpO
range. Pulse oximeter SpO readings were compared to SaO
2
as ± "X" digits. This variation equals ± one standard deviation (± 1 SD), which encompasses 68%of the population. Oxygen saturation accuracy can be
affected by certain environmental and patient physiological conditions, as discussed in the operator's manual for the monitor. Use Nellcor sensors only
with 250cx Series Monitors containing Nellcor oximetry. Consult individual manufacturers for accuracy specifications and compatibility information
of particular instruments and Nellcor sensor models. The volunteer population was composed of healthy men and women recruited from the local
population. The ages ranged from 18 to 50 years old, with variations of skin pigmentations.

3) Applicability: OxiMax MAX-A, MAX-AL, MAX-P, MAX-I, and MAX-N sensors.
4) Information of wavelength range can be especially useful to clinicians performing photodynamic therapy.
NOTE: Because pulse oximeter equipment measurements are statistically distributed, only about two-thirds of pulse oximeter equipment measurements
can be expected to fall within ±
