WebCarboxyhemoglobin causes pulse oximeters to register artificially high Spo2 values. This is because carboxyhemoglobin absorbs very little light in the infrared range, but as much light as oxyhemoglobin in the red range. Thus, oximeters “see” carboxyhemoglobin as oxyhemoglobin and display the approximate sum of both hemoglobins as Sp o2.
