Interfering Substances
Carboxyhemoglobin and methemoglobin may erroneously increase oxygen saturation readings. The
level of increase is approximately equal to the amount of carboxyhemoglobin and/or methemoglobin
present. Dyes, or any substance containing dyes, that change usual arterial pigmentation may cause
erroneous readings.
