Introduction: Pulse oximetry is widely used to measure blood oxygens saturation (SpO2) and acclimatization status in order to assess acclimatisation status at altitude and there is evidence suggesting that SpO2 during exercise is more relevant than measurements at rest. But movement, especially of t...
