Respiratory Gas Analysis
By interrogating the gas exchange occurring in the lungs during breathing we can learn a lot about respiratory processes.
The exchange of gases (O2 & CO2) between the alveoli and blood occurs by simple diffusion: O2 diffusing from the alveoli into the blood and CO2 from the blood into the alveoli. Diffusion requires a concentration gradient. So, the concentration (or pressure) of O2 in the alveoli must be kept at a higher level that in the blood & the concentration (or pressure) of CO2 in the alveoli must be kept at a lower level than in the blood. We do this by breathing - continuously bringing fresh air (with a high percentage of O2 and much smaller fraction of CO2) into the lungs and alveoli.

Integrate with other physiological recording options
In conjunction with our complete system shown below, any device (i.e. ergometer, exercise bike, treadmill) with an analog output (+/- 10V) can be connected to a PowerLab data acquisition system for synchronization of event in LabChart. So you have even more flexibility and can integrate all your data streams in one place.
All of our hardware recommended for human use is backed by the appropriate safety certification standards. More information on safety standards.
