Abstract
A breath testing apparatus is provided to test hydrogen sulfide and other parameters in exhaled breath of a patient. A patient sample input for receiving exhaled breath from a patient is provided, in addition to an atmospheric input for receiving atmospheric air. A valve is coupled to said patient sample input and said atmospheric input, and first and second pathways are provided from said valve to a hydrogen sulfide sensor block and a second sensor block.
