text: Because oxyhemoglobin (O2Hb) and carboxy-Hb (COHb) absorb red light (660 nm) similarly and carboxy-Hb (COHb) absorbs very little near-infrared light (940 nm) (see Figure 5 below), the photodiode of standard pulse oximeters – that only emit red and near-infrared light – cannot differentiate between oxyhemoglobin (O2Hb) and carboxy-Hb (COHb).
