Abstract
A method of detecting and quantifying cyanide concentration in a patient, by monitoring photometric changes resulting from the transformation of methemoglobin to cyanomethemoglobin. The present invention provides for a means of cyanide poisoning assessment in patients using the affinity of methemoglobin for cyanide to assess the photometric changes resulting from methemoglobin converting to cyanomethemoglobin, as an indicator of cyanide concentration in a patient. Appropriate corrective action can then be promptly taken.
