The main objective of the present study is to develop and test a relatively low cost microcomputer-based metabolic monitoring system that is capable of computing the oxygen consumption and minute ventilation of individuals, while at rest or at work, on an on-line basis. The design, specifications, and merits of the system are given. The software package developed was written in assembly language for the IBM AT personal computer. The experimental evaluation of the microcomputer-based metabolic monitoring system showed that there is a high degree of correlation between computer and manual calculations. The correlation coefficients between manual and computer calculations were 0.9986 and 0.9966 for minute ventilation and oxygen consumption respectively which indicate that the system developed is highly accurate.
