BBB1LP Breath-by-Breath Respirometry Package

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 includes:

  • Connector.


    Rapid Response O2/CO2 Analyzer

  • Connector.


    Wireless Heart Rate Monitor

  • Connector.


    Pneumotach Spirometer (x6)

  • Connector.


    Logger Pro Software and custom experimental files

  • Connector.


    Lab Quest Mini Data interface x2

  • Connector.


    Flowmeter 40-500ml/min

  • Connector.


    Face masks (2 Large, 2Med)

  • Connector.


    Neoprene face mask holder

  • Connector.


    Nafion RH equilibrator tubing

  • Connector.


    Flow calibration kit, tubing, connectors, drying column, CO2 scrubbing column, pneumotach adaptor, screwdriver, data cables

When running experiments using the Breath by Breath Respirometry Package, the user wears a light-weight face mask (or a breathing tube if preferred) that allows for breath sampling during rest or during exercise on a variety of ergometers. 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.

The BBB1LP-Respirometry Setup experimental file automaticaly calculates and displays all of the breath paramters in the 9 panel Wasserman plots when data logging is complete.

BBB1LP Package can also be used in spirometry only studies where breath flow is measured and various lung paramters are calculated automaticaly
