Screening for emphysema via exhaled volatile organic compounds.

Diagnosis by Volatile Organic Compounds in Exhaled Breath from Lung Cancer Patients Using Support Vector Machine Algorithm

Monitoring exhaled breath is a very attractive, noninvasive screening technique for early diagnosis of diseases, especially lung cancer. However, the technique provides insufficient accuracy because the exhaled air has many crucial volatile organic compounds (VOCs) at very low concentrations (ppb level). We analyzed the breath exhaled by lung cancer patients and healthy subjects (controls) usin...

Exhaled biomarkers in lung cancer.

Lung cancer is the leading cause of cancer death. Results of therapeutic interventions are particularly discouraging when the disease is discovered in an advanced stage. Early diagnosis is limited by the fact that the disease usually develops asymptomatically and available screening methods do not fulfil the requirements for reliable discrimination between patients with lung cancer and subjects...

Breath Tests in Respiratory and Critical Care Medicine: From Research to Practice in Current Perspectives

Today, exhaled nitric oxide has been studied the most, and most researches have now focused on asthma. More than a thousand different volatile organic compounds have been observed in low concentrations in normal human breath. Alkanes and methylalkanes, the majority of breath volatile organic compounds, have been increasingly used by physicians as a novel method to diagnose many diseases without...

Exhaled Gas Detection for Medical Diagnosis: Can it be Made a Tool for Self-Screening?

Exhaled gases and volatile compounds have relation with health status of the human body. Detection of these compounds can be used as a non-invasive tool for early diagnosis of diseases such as cancer. If reliable low cost point-of-care devices that can selectively respond to these gases and organic compounds are developed, normal people can use them for routine self-examinations and get an earl...
