The target SpO2 for COPD patients at risk for hypercapnia is 88-92%. An SpO2 of 88% on 2L nasal cannula is at the lower limit, and when combined with altered mental status, it indicates the patient is decompensating despite therapy.
Do not assume a low-normal SpO2 is acceptable if neurological changes are present. Confusion in this context is a hypoxemia emergency, not just a symptom of infection or age.
