Respiratory Exchange Ratio (RER) is the ratio between the volume of Carbon Dioxide produced and the volume of Oxygen being used (VCO2 /VO2).
Metabolic function during exercise is most often analyzed by interrogating the gas exchange occurring in the lungs of an exercising subject.
For a typical metabolic study for exercise physiology, the following variables are recorded:
Record multiple
signals at one time
Complete
systems
Mix and match products
for a custom solution
Integrate with wireless
physiological 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.

The simultaneous measurement of respiratory gas concentrations and airflow with our metabolic systems permits the calculation of the following metabolic signals:
Respiratory Exchange Ratio (RER) is the ratio between the volume of Carbon Dioxide produced and the volume of Oxygen being used (VCO2 /VO2).
Spirometry is a non-invasive method of lung function testing, which measures the volumetric flow rate of air inhaled and exhaled. From this respiratory flow signal respiratory volume for a given time frame can be calculated using a simple integral.
The changes in this gas mixture between inhalation and exhalation, combined with a measurement of respiratory flow, can be used to estimate metabolic rate.
Temperature is a useful tool in determining many factors such as subject health or the stability of an experimental preparation. It is also usefulas a calculation factor for comparing measurements taken in different states.
Accurately measure the volume of gas exhaled during respiration.

The comments feature in LabChart is a great way to mark events of special interest during recording, for example increased speed or change in activity. During analysis, you can then use these comments to quickly and easily navigate LabChart Data Files. If you have planned events, you can also preset comments prior to recording.
