Spo2 normal range by age - Average Oxygen Level by Age

Oxygen saturations should be targeted within the range of 91-95%, when receiving oxygen therapy, in both preterm and term neonates.

Pulse oximetry normal range Normal pulse oximetry value is generally considered to be in the 95-98%.

A microprocessor in pulse oximeters uses this ratio calculated over a series of pulses to determine the SpO2 based on a calibration curve that was generated empirically by measuring R in healthy volunteers whose saturations were altered from 100% to approximately 70%5 Figure 4C.

SpO2 is another oxygen level for any period of time between.
