Carboxyhemoglobin/Hemoglobin.total in Arterial blood by Pulse oximetry
COHgb % BldA PulseOx
Definition
- Used to report the carboxyhemoglobin level as a percent of the total hemoglobin using pulse oximetry. Note that conventional pulse oximeters are not used to measure carboxyhemoglobin because they use two wavelengths of light that does not allow distinction between carboxyhemoglobin, methemoglobin, and oxyhemoglobin. However, newer pulse oximeters use multiple wavelengths (e.g., seven, eight or twelve) that allow separate measurement of carboxyhemoglobin. [PMID: 21459480]
