Abstract

BACKGROUND:

The authors performed a prospective study to determine whether breath test analysis using an electronic nose correlates with a clinical pneumonia score.

METHODS:

Exhaled gas was sampled from the expiratory limb of the ventilator in mechanically ventilated surgical intensive care patients and assayed with the electronic nose. Components of a clinical pneumonia score were recorded concurrently.

RESULTS:

The score predicted by the electronic nose showed good correlation with the actual pneumonia score (r = 0.81). Bland Altman analysis showed a mean bias of 0.0 (limits +/- 2.6).

CONCLUSIONS:

The electronic nose is a new biosensor technology that correlates with a clinical pneumonia score.
