Aconcagua O2 Saturation Readings

Oxymeter. Aconcagua O2 Saturation Readings

On each of Aventuras Patagonicas Expeditions, oxygen saturation readings are taken daily for each client. We use pulse oximeters to daily monitor your acclimatization, by checking your oxygen saturation level. The procedure is harmless and easily done within seconds. This process gives us a tremendous amount of information about your acclimatization process and we have found it essential to the safety of our clients. We have attached below a sample of the readings of one of our Expeditions from last season. O2 saturation and heart rate are giving at each camp.


The first number is the O2 Saturation and the second is heart rate.
