Abstract
A method for detecting the occurrence of a condition in a respiring subject includes the steps of: introducing emitted subject respiratory gases to a gas sensing device; detecting certain species present in the emitted subject respiratory gases with the gas sensing device; and correlating the presence of the species with the occurrence of the condition.
Claims19
A diagnostic method for diagnosis the condition of a patient comprising:
- introducing exhaled respiratory gas of a subject to a gas sensing device having an array of gas sensors,
- detecting certain species in he exhaled respiratory gas with said device and producing a output pattern according to said certain species,
- correlating the output pattern with a plurality of known output patterns, each of said known output patterns corresponding to a different condition of the patient,
- diagnosing a condition of the patient based on said correlation.

A detector for detecting the occurrence of a condition in a respiring subject comprising:
- a gas sensing device including an array of gas sensors responsive to certain species and configured to generate response signals in response to said certain species, said gas sensing device structured to produce an output signal corresponding to said response signals;
- means for introducing respiratory gases exhaled by a subject to said gas sensing device;
- a correlator configured to correlate the output pattern with a plurality of known output patterns, each of said known output patterns corresponding to a different condition of a subject,
- a diagnoser configured to recognize the occurrence of a condition in the respiring subject from the output pattern correlation.
