Validity and Reliability of the TEEM 100 Portable Metabolic Measurement System

Abstract

This study examined the validity and reliability or consistency of a portable gas analysis system (TEEM 100) used for the measurement of oxygen consumption. Eight males were evaluated at rest and during several work intensities while expired air was collected and analysed in series with the TEEM 100 and a reference collection system (Tissot gasometer and Ametek gas analysers). Subjects were tested on 2 separate days for comparison of 2 TEEM 100 systems. The data revealed that either collection and analysis method was reliable or consistent from day to day. However, significant and unexplained differences were found between methods for expired ventilation, expired gas fractions and the calculated oxygen consumption. These differences became greater at higher flow rates or work intensities. It was concluded that the TEEM 100 is a consistent gas exchange measurement system. Its validity, however, should be viewed with caution.
