Q-Box HR1LP Human Respiration

Home Products Q-Box HR1LP Human Respiration

The Q-Box HR1LP Human Respirometry Package allows users to conduct numerous safe, exciting investigations in respiratory and cardiovascular physiology. This package is designed for mixed-expired air analysis for CO2 and O2 exchange. It is simple to set up and operate. The Q-Box HR1LP is ideal for human respirometry research but simple enough for use in teaching undergraduate laboratory courses.

The Q-Box HR1LP Human respirometry Package monitors CO2 and O2 continuously in mixed expired air and calculates changes in VO2 and VCO2.  Spirometry portion of the package provides measurements of breathing frequency, relative breathing pattern and heart rate data  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.

“When purchasing a new gas exchange system for research purposes, I took a chance with Qubit systems; they claimed to produce a competitive system at almost half the price of those of more established companies. I am happy to say that I am entirely happy with my decision. I now have a reliable and versatile system that is just as accurate as the more expensive competition and, because it is modular, can be expanded as my needs evolve. Most importantly, I received outstanding service during all phases of purchase: conception, ordering, installation and continuing help.”
