Oxymax-H is Columbus Instruments' non-clinical metabolic monitoring system. The instrument employs the same analytical grade gas sensors employed in the entire Oxymax line. Measurements are made by affixing a mask or canopy to the subject through which a continuous flow of air is drawn. The rate is selected so as to collect all expired gases from the subject. The flow is accurately metered by a precise controller that measures the exact mass of air being transported. A small sample is drawn from the effluent flow, dried, and presented to an electrochemical Oxygen sensor (paramagnetic and zirconia sensors also available) and a single beam non-dispersive Carbon Dioxide sensor. The resulting values are processed by the Oxymax H controlling software for presentation of Oxygen consumption, carbon dioxide production, respiratory exchange ratio, and heat.
Oxymax H may also be employed in situations where the use of a mask may not be suitable; it works equally well with a tent or canopy.
