The correct measurement of oxygen saturation at high altitude

ConclusionsThe correct pulse oximetric determination of SpO2 at high altitude requires a standardized measurement procedure; the investigator is familiar and trained. Anyway, the measurements have to be done in the continuous mode of the pulse oximeter over a sufficient timeframe (3 SpO2-fluctuation cycles; 2 –3 min). We recommend to record the maximum and the minimum value of the measurement interval and to use a pulse oximeter device with memory function.
