Background levels of hydrogen cyanide in human breath measured by infrared cavity ring down spectroscopy.


Hydrogen cyanide (HCN) in breath has been suggested as a diagnostic tool for cyanide poisoning and for cyanide-producing bacterial infections. To distinguish elevated levels of breath HCN, baseline data are needed. Background levels of HCN were measured in mixed exhaled air from 40 healthy subjects (26 men, 14 women, age 21-61 years; detection limit: 1.5… (More)
