WebOct 2, 2024 · Methemoglobinemia typically causes the pulse oximeter to report a saturation of ~82-86% (even if the PaO2 is very high). In a hospital, this will be interpreted as “refractory hypoxemia” (saturation in 80s despite 100% FiO2). Patients will be treated with high-dose supplemental oxygen and the ICU may be consulted.
