Health Care in One Breath
Respiratory Gas Measurement System for Non-invasive Diagnosis with Pyroelectric Detector
„Please strip to the waist.“ Medical examinations still frequently begin with this sentence. Still. This sentence could very soon be: „Please breathe out strongly.“ For research in the field of respiratory gas measurement systems are making considerable progress. The aim is clear: To make the diagnosis of illnesses easier and painless.
Several pricks in the fingertip or taking a blood sample several times from the vein – the diagnosis of diabetes is mostly accompanied nowadays with the repeated measurement of sugar levels in the blood. But you can smell diabetes. A slightly sweet fruity odour in the breath indicates the presence of this metabolic disease.
Biomarkers as indicators of diseases
Meanwhile this admittedly very vague examination method can be put on a sound footing. This is because a person’s breath resembles a gaseous profile of their state of health. This contains several hundred volatile organic compounds. Many of these compounds (as so-called biomarkers) reliably indicate diseases. The biomarker for diabetes is, for example, acetone, which is a fat reduction product.
