C901 LoggerPro  software supplied with the Human Respirometry Package displays breathing frequency, relative breathing pattern, heart rate data as well as O2 and CO2 concentration in the exhaled breath, as they are collected. This enables the user to follow changes in these variables as they occur during the various experimental procedures.  Exhaled air is sub-sampled from a Breath Mixing Bag and pumped through the gas analysis system at a known flow rate. From the  change in O2 and CO2 concentration in the breath mixing bag, VO2, VCO2 and respiratory exchange ratio are calculated. From the average breath flow minute ventilation rate (VE) is also calculated.  During spirometry measurements vital capacity maneuvers can be performed to obtain Flow-Volume Loops and Volume-Time plots.   Calculations of various lung volumes and capacities are done in the software.


  • Versatile, modular, easy to use, gas exchange system for VCO2 and VO2 measurements
  • Includes Spirometry module for lung capacity and volume measurements
  • Easily adaptable to animal respiration measurements with additional accessories


  • Human Respirometry Measurements
  • VO2, VCO2 Measurements During Rest and Mild Exercise
  • Heart Rate Measurements
  • Tidal Lung Volume and Vital Lung Capacity Measurements
  • Minute Ventilation and Breathing Capacity Measurements


Example of experiments with Q-Box HR1LP Human Respirometry Package:

  • Effects of isotonic exercise on VE, VO2, VCO2 and respiratory exchange ratio
  • Effects of hyperventilation and breath holding on respiration and heart rate
  • Effects of re-breathing and increased dead space on respiration and heart rate
  • Effects of diet, caffeine, etc. on metabolism
  • Differences in lung volume and capacity between individuals
  • Simulations of obstructive lung disease and its ettect on Flow-Volume plots
