Abstract:
A simple, non-invasive, colour-based carbon dioxide (CO2) indicator is described. The indicator provides an indirect response to the rapid, aerobic microbial colonisation of an underlying wound when used in conjunction with an occlusive (i.e. sealed) dressing. The indicator has potential as an early warning indicator of infection in chronic wounds.
