TECHNICAL INFORMATION IN ITALICS BLUE BELOW WAS TAKEN FROM THE WEB:

Metabolic Calibration uses the principle of mass preservation to create known VO2 and VCO2. The principle of mass preservation dictates that the chosen mass flow of CO2 and O2 remains unchanged regardless of the ventilatory dilution (i.e. the minute ventilation that delivers it into the system under calibration).

This top of the line metabolic calibration gas titration device consists of a Mass Flow Controller capable of delivering any set point flow of this gas (~21%CO2, 79%N2) within a range of 0 - 20 liters/min STPD and a Set Point Module (SPM) which enables selection of desired mass flows.

Four switch-selected VO2 settings are 1, 2, 3 and 4 liters per minute of VO2 and VCO2. (Model 17057 has additional 5 and 6 liter settings) The exact value will depend on physical parameters, such as barometric pressure, air temperature and relative humidity. The provided O2CAL.xls spreadsheet software enable precise determination of the selected metabolic rate and the percentage error of the metabolic measurement system being calibrated.

The remaining two positions of the rotary switch correspond to a Zero flow setting and a continuous 10-turn potentiometer-operated selection of any desired mass flow from zero to 4 L/min.

Metabolic Calibration accuracy is +/-1% VO2 & VCO2.

Most flow sensors are typically calibrated with a fixed volume manual syringe, but little is known about the performance of that flow sensor over the whole physiological range.

This device includes a mass flow controller to produce precise Metabolic Calibration gas mixtures to verify VO2 and VCO2. It provides highest accuracy and ease of adjustment.

So how does this affect the accuracy of your ventilation measurements (and ultimately VO2) when you have calibrated the flow sensor at some unknown manual stroke speed, then use the sensor for low-flow pediatric or resting measurements, or high flow VO2max measurements?

What this device can be used for:

Produce an exact, simulated VO2 and VCO2 to verify the overall accuracy of a metabolic measurement system and its software.

Check the accuracy of any flow / volume measurement device.

Simulate breathing at rates from 6 to 80 breaths per minute.

Check the effects of various gas mixtures on a flow sensor.
