BBB1LP Breath-by-Breath Analysis

Qubit’s BBB1LP Breath by Breath Respirometry Package is designed to measure both steady-state and dynamic changes in human metabolic rate under a variety of test conditions. VO2, VCO2, VO2max, resting metabolic rate (RMR), Respiratory Exchange Ratio (RER) and a host of other physiological and pulmonary parameters may be measured on a breath by breath basis using this package.

The Breath-by-Breath Respirometry Package is easy to set up and use, and has all the accuracy of metabolic cart systems which cost many times more. All of the accessories such as face masks, holders, flow calibration kit etc. are supplied with the package.  Inhaled and exhaled breath is analyzed by the rapid response O2/ CO2 analyzer (S147) at a sampling rate of 50 Hz so that the entire breath wave form is displayed graphically in real time. The breath wave form and end-tidal O2 and CO2 are clearly displayed, even during vigorous exercise. All data are collected and displayed graphically.  Data interface and software (compatible with both PC and Macintosh) are supplied with the package.
