Pulse oximeters cannot be fully relied upon to identify or prevent severe AMS. They can provide vital clues as to whether a person is suffering from a lack of oxygen, especially when they indicate low oxygen levels in the blood. However, when pulse oximeters indicate high oxygen levels in the blood, this is not to say that a person is safe from severe AMS.
Therefore, pulse oximeters should only be used by well-trained professionals who know how to interpret the results, and cannot be used as replacement for other safety measure. With that in mind, pulse oximeters can play a central role in the early identification of clues that could indicate AMS.
