While breath analysis is most commonly known for its ability to detect alcohol consumption, it has the potential to extend far beyond that use. Breath analysis has the ability to diagnose a wide range of human conditions, and is now being utilized to aid the bottlenose dolphin.

Engineers from the University of California, Davis have developed a device for collecting dolphin breath for analysis. Because invasive techniques such as skin biopsies and blood sampling are difficult to perform on wild dolphins, this device will make it easier to check the health of the marine animals, study their biology, and aid in wildlife conservation.

This from UC Davis:

The researchers designed an insulated tube that traps breath exhaled from a dolphin’s blowhole and freezes it. They analyzed samples to create profiles of the mix of metabolites in breath, established baseline profiles of healthy animals and were able to identify changes in the breath of animals affected by disease or other factors. The researchers concluded that breath analysis could be used to diagnose and monitor problems in marine mammals – and, by extension, in ocean health as well.
