Exhaled breath is unique fingerprint

7 posts in this topic

Compounds present in exhaled breath can act as a "fingerprint" for individuals, scientists say.

These "metabolites" represent the waste products of the body's chemistry - but their uniqueness had never been shown.

A study in PLOS ONE suggests they could be as useful to medical diagnosis as those found in urine or blood.

I think a small hand-held device would be handy in an emergency situation when a patient cannot adequately verbalise his/her medical history. Maybe your breath has a chemical signature for any drugs you're taking for, say, a blood disorder or for high blood pressure, etc.

In light of the newer EKG monitors and their ability provide an expeditious and fairly accurate description of a heart rhythm; having a portable breath analysis tool would be a huge advantage for paramedics addressing a medical incident.
