Abstract
A method of detecting cyanide concentration in the cutaneously transpired gas of a patient, allowing for the timely implementation of an appropriate treatment. Where the skin of a patient suffering from cyanide poisoning has been burnt, the present invention provides for a noninvasive means of cyanide treatment. In practice, a material is impregnated with methemoglobin and attached to a patient's skin. A barrier means located between the impregnated material and the patient's skin allows for the transfer of cyanide gas from the patient into the material. However, this barrier means does not allow for the transfer of the methemoglobin from the impregnated material into the patient's skin. The material is monitored for photometric change, and, where a change indicative of cyanide poinsoning is present, appropriate treatment is administered.
