Until now, pulse oximeters could only measure and display functional oxygen saturation (SpO2), so when patients had elevated carboxyhemoglobin (from carbon monoxide poisoning) and/or elevated methemoglobin (negative reaction to more than 30 common drugs used in hospitals) the displayed functional oxygen saturation overestimated the actual oxygen saturation value.
