Breath analysis is a promising field with great potential for non-invasive diagnosis of a number of disease states. Analysis of the concentrations of volatile organic compounds (VOCs) in breath with an acceptable accuracy are assessed by means of using analytical techniques with high sensitivity, accuracy, precision, low response time, and low detection limit, which are desirable characteristic...
Changing ocean health and the potential impact on marine mammal health are gaining global attention. Direct health assessments of wild marine mammals, however, is inherently difficult. Breath analysis metabolomics is a very attractive assessment tool due to its noninvasive nature, but it is analytically challenging. It has never been attempted in cetaceans for comprehensive metabolite profiling...
halitosis generally refers to the unpleasant odor of breath irrespective of its origin. oral malodour could result in diverse problems in daily life such as social embarrassment and can adversely affect individuals’ social interactions. though many oral and non-oral sources could give rise to halitosis, it was mainly associated with oral cavity conditions and volatile sulfur compounds –prod...
This paper presents a dual approach to the study of breath sounds in singing, consisting of an acoustic analysis of breath sounds, and development of an automatic breath detection system. Previouswork on automatic breath detection were based on relatively simple features that were postulated to be relevant to the detection. In contrast, this study starts with a detailed acoustic analysis of bre...
The purpose of this review is to highlight the advances in technology and understanding in the field of breath analysis for medical diagnosis. A critical review of the methods of breath collection, treatment, and analysis is given, highlighting the problems facing the field and areas where promising advancement has been made. One particular area of interest is centered around electronic noses, ...
