The MC-214 Metabolic Cart from iWorx is a compact, economical system capable of measuring breath-by-breath oxygen consumption and carbon dioxide production in resting and exercising subjects. Rates of oxygen consumption (VO2) and carbon dioxide production (VCO2), respiratory exchange ratios (RER), basal metabolic rates (BMR), aerobic capacities (VO2max), and more are easily determined using the iWorx LabScribe2 analysis software included in the system. The MC-214 includes:
The iWorx GA-200 CO2 /O2 Gas Analyzer
IX/214 Data Acquisition System with LabScribe2 Software
SP-304 Spirometer with a reusable 300L/min flowhead
Mask and headgear
PT-104 Pulse Plethysmograph for recording heart rates
An optional high capacity, 1000L/min flowhead is available.
The GA-200 Gas Analyzer
The GA-200 CO2 and O2 Gas Analyzer is a high performance analyzer that is capable of measuring breath-by-breath changes in the respiratory gas concentrations because of its rapid response time of 10 milliseconds, which is an effective sampling rate of 100 samples per second. The GA-200 uses laser diode absorption technology to measure oxygen concentrations from 0-100%, and infrared detection to measure carbon dioxide concentrations from 0 to 13%.
The GA-200 has a fluorescent display for programming the unit and observing measurements, a keypad for programming the unit’s operation and calibration, and analog outputs that allow the unit to be easily connected to the IX/214 data recording unit. The unit is calibrated at the factory and is ready to take measurements immediately. Just connect the GA-200 to the recorder and the spirometer and the system is ready to record VO2 and VCO2.
The IX/214 Data Acquisition Unit
The MC-214 system includes the IX/214, which is a rugged, reliable, four-channel data recorder that is engineered to take years of classroom use and abuse. The IX/214 enclosure is constructed from extruded aluminum, with a minimum of student-accessible controls and adjustments. The IX/214 includes a dual-channel biopotential amplifier designed for use on human subjects. Two additional channels accept practically any sensor you are likely to encounter, as well as voltage output of pH meters, spectrophotometers and other laboratory devices. A fully functional built-in stimulator useful for a variety of human and animal labs is also included in the IX/214.
Key Features of the IX/214
The IX/214 carries a three-year unconditional warranty.
Stimulator is built-in to the recording unit.
Intelligent inputs adjust transducer gain automatically.
Software is upgradeable free-of-charge over the web.
Sampling speeds of 1 to 100 kHz continuous and 1 to 100 kHz snapshot.
Electronic design meets or exceeds UL safety standards for lab use and is CE certified.
The LabScribe2 Software
LabScribe 2, the recording software used with IX/214, is easily configured to record the outputs of the GA-200 gas analyzer and the SP-304 spirometer with one click of the computer’s mouse. Through the use of computed functions specifically designed for use with the MC-214, the respiratory volumes and the concentrations of oxygen and carbon dioxide are integrated with each other to provide the VO2 and VCO2 of the subject.
System Requirements for the IX/214
The IX/214 operates on Windows or Macintosh computers via the USB bus, which provides aggregate sampling at 100 kHz continuous, more than fast enough for just about any teaching experiment. Windows computers must have at a minimum a Pentium II or Celeron level 500 MHz computer running Windows 98, ME, 2000, XP or Vista with 512 MB of memory. Macintosh computers must be running OSX 10.3 with 512 MB of memory.
Courseware for the MC-214
The MC-214 metabolic cart is provided with a collection of laboratory exercises that cover the following topics:
Breath-by-breath measurement of VCO2, VO2, and RER in resting and exercising subjects.
Breath-by-breath measurement of BMR in resting and post-exercise subjects.
Breath-by-breath measurement of VO2 max.
Measurements of VCO2, VO2, and RER using a mixing chamber.
Measurement of BMR using a mixing chamber.
